Chocolate Flower: You Can Grow That!

The daisy-like flowers of chocolate flower have a chocolate scent!

No, I’m not kidding. There is a flower that grows well in the Southwest that smells like chocolate. It’s like my two favorite things in one pretty package! Chocolate flower (Berlanderia lyrata) casts its rich scent throughout your garden. Be sure to plant it where you can bend over and take a whiff on those occasional days with no breeze. It’s an easy plant to grow and care for.

Native to Dry Areas

No wonder chocolate flower is easy to grow in New Mexico; it is native to dry plains and hills of New Mexico, Arizona, Colorado, Texas and Kansas. It grows best in elevations of 4,000 to 7,000 feet, so Berlanderia thrives in high deserts and intermountain areas like mine.

Because it’s native, and probably because it looks and smells so great, chocolate flower attracts butterflies, bees and birds. And deer leave it alone! Need more reasons to grow chocolate flower? It reseeds naturally, but not aggressively, so one plant can turn into a few or more, depending on lots of conditions and where you plant the first one. Another great feature of this native is that it will reseed more naturally if planted near rocks or gravel mulch. The rocks “trap” the seeds when they blow in the wind.

Caring for Chocolate Flower

You can plant chocolate flower in nearly any type of soil, but it probably will do best if the soil drains well. Be sure to place it where it will receive plenty of sun – up to all day – and where its mature height (about a foot to 15 inches tall, and up to two feet wide) will work without overcrowding. Give it a little more water the first year, and then chocolate flower should grow and bloom with mostly rain only. Each spring, trim off dead flower stalks and some of the foliage if necessary to keep the plant base about three inches high.

unopened and spent blooms of chocolate flower plant
I first had trouble telling spent blooms from new ones for deadheading. Unopened blossoms have a pretty green and papery look. The circled one is a spent, dyring up bloom for deadheading or seed collection.

Chocolate flower is a perennial in zones 4 through 11, although ask for the variety best for your area. For example, High Country Gardens has introduced a new Mora County mix of B. lyrata that is particularly cold hardy (Mora County is a mountain and high plain area just northeast of Santa Fe). Deadheading, or removing spent blooms, keeps Berlanderia blooming.

I love the shape, color and scent of chocolate flower. When it and desert zinnia bloom at the same time, it’s a color explosion.

Enjoy Growing Chocolate Flower

Chocolate flower is in the daisy family, a relative of the sunflower and others, so it makes a nice cutting flower as part of an arrangement. You can bring that soft chocolate scent inside! I love the color of the flower buds – they look like a sage green paper flower. Its growth habit is bright and colorful but just wild enough to fit in a natural looking, xeric landscape. Leave some of the drying flower heads on your chocolate flower at the end of the season if you want it to reseed in your garden. Then watch in spring. If conditions are right, you might see a few new crowns of chocolate flower with the distinctive leaf pattern.

See how this chocolate flower grows up against the rocks. You will learn to recognize the leaf shape.

It’s a good thing chocolate flower can spread, because you can’t move it. The plant has a tap root (which helps its drought tolerance) that doesn’t survive division or transplanting. Otherwise, chocolate flower is a perfect, sunny perennial for a xeric garden.

Gardening Basics

My mantra is “Gardening Should be Fun.” Taking the pressure off makes it more fun. In other words, your garden doesn’t have to look like the cover of a magazine or top Pinterest pages for you to enjoy the process and the results.

So, if you are a new gardener or have a friend or relative who wants to grow plants and doesn’t know where to start, you can watch my online course with the basic terms and concepts. I developed the course for Southwest Gardening Blog, where I am one of four gardeners/authors.

The online class  only is available through February 28, so be sure to sign up soon. You can watch it whenever it is convenient and as often as you like. Have fun with plants!

The Root of the Matter

 

sprout roots cross section

It’s easy to spot possible problems with a plant’s leaves, stems or flowers. Those are the parts we enjoy seeing every day in our garden. But what about the parts that lie beneath the surface of your garden or container?

We can forget all about the roots when enjoying a plant’s shape and color. But some of the toughest tricks to gardening involve root care – watering enough but not too much; soil drainage to allow roots to gather water but not sit in them; ability for roots to take up oxygen, and ability of roots to grow outward to support the plant you see above ground. How do you know your plant’s roots are healthy and why is it important?

Roots Affect Plant Health

The way roots grow, and their health, have a profound effect on the size a plant reaches, its vigor, and how it responds to watering or other care you give the plant. The main function of these leafless, underground stems is to absorb moisture and nutrients from the soil around them. The roots store the plant’s food to keep it nourished and alive. Roots also help stabilize a plant in the soil or potting mix and physically support the plant’s main stem or trunk.

A carrot is a taproot.

Types of Roots

There are various types of roots, although most root systems branch out under the soil. You might have heard of a taproot, which is a primary root that grows straight down into the soil and develops few to no root branches. Picture a carrot. The part we eat actually is a taproot. That’s the good kind, but a taproot can be a problem for gardeners. Some trees, such as pecans, grow deep taproots. This makes them much more difficult to dig up and transplant.

Some roots have lateral, or secondary, roots that branch off from an existing root. This happens with fibrous roots because their primary root eventually stops lengthening. Fibrous roots are lighter and smaller in diameter because they have less cell activity than standard roots.

One of the biggest problems with roots is restriction of their growth. This is easy to see when you lift a new plant out of its nursery pot. Some have roots circling in the shape of the container; the roots received good nutrition from the potting mix and plenty of water from garden center staff, but had nowhere to go. When planting, always dig a hole larger than the root ball – up to three times as large for trees and shrubs. And loosen the soil around the outer edges of the hole. If the ground is compacted and dense, roots will have to work harder to spread.

wilting zucchini plant from disturbed roots
This zucchini looks bad. Because I ripped its roots when I moved the pot.

A second problem is underwatering (especially a tree) or watering in brief, shallow periods instead of long, deep soaks. Short watering doesn’t penetrate very deeply, so the roots grow close to the surface. And that can bring on other problems, including damage from lawnmowers or foot traffic. But with less frequent and deeper watering, roots grow downward as they seek moisture.

Roots as Plant and People Food

For plants, the structure and quantity of roots help determine how much water and nutrition the plant takes in. That’s why it is so important to water a plant more in its first season or year of growth than it will need later. The extra water helps those roots take hold and grow so they can store food for the plant.

Beet roots and leaves are edible.

 

Aside from carrots, potatoes, sweet potatoes, radishes and beets are among common roots people eat. The mature root – a tuberous root in the case of a potato or sweet potato – holds lots of nutrition.

One final tip – buying a plant that has roots wrapped around inside the pot (rootbound) can make for more challenges when you plant it. You should tease or slice the roots near the outer bottom to help stimulate new growth. But if a plant’s roots are brown or dry, move on to another plant.

 

 

 

 

 

 

 

Protecting Plants in Your Garden

In this dry year, I feel like our plants are under a triple threat from drought, strong winds and unusual heat for this early in summer. I’ve decided the drought and lack of plant growth on our land and the forest near us has caused insects and larger critters to eat more (and different) plants than usual because they’re hungry or thirsty.

gopher spruge-santolina-thread-grass-rock-garden
Some plants manage in heat and wind, like this gopher spurge, santolina and thread grass.

At any rate, we’re spending way more time watering, covering or doing damage control than we’ve ever had to do in previous years. Here are a few plant attackers and some ideas for fighting them:

jimson-weed-datura-plant-with-blooms
Datura, or jimson weed, thrives in dry heat.

Drought. The first protection is to choose native drought-tolerant plants. A few of ours, namely the santolinas and Datura (jimson weed) have thrived despite no supplemental watering. For the first time in five years, we’re having to water other plants in our rock garden typically immune to short periods of drought. And the rain barrel is running low.

pecan-mulch-lily
We placed a thin layer of pecan bark mulch around these plants last spring. It helps them in cold, heat and drought.

As with ornamental plants, water edibles like tomatoes early in the day and in consistent amounts. They shouldn’t remain wet, but a little moisture in the soil helps them fight dry, windy and hot conditions. Mulching around as many plants as you can (save a few that don’t like wet roots, such as lavender and rosemary) can help them stay damp longer. Finally, remember plants recently moved or planted after purchasing from a nursery need extra water during dry, hot conditions their first year or so.

fabric-covers-vegetables
We have shade cloth that we can lift over our tomato plants when the heat peaks and row cover over basil and strawberry beds.

Heat. Mulching also cools the ground above a plant’s roots, helping the plant get through blazing heat. Sometimes watering is all you can do to protect a plant in record heat. But if the plant is in a container, scoot it into an area that’s slightly shadier or has shade during the time of day when your heat typically peaks. We have been covering our tomato plants with shade cloth this year soon after temperatures soar above 90 degrees. In the past, we’ve had problems with blossoms and fruit set when temperatures soared. Prevention also helps for heat. It’s wise to plant as close as possible to the recommended date for your area. This year, we were traveling and planted later than normal, so our plants had less time to toughen up before heat struck and we paid for that.

lawn-chairs-over-plants
Planting late or having record heat might mean adding shade protection for new plants. Be sure to secure light objects like these “repurposed shading materials” to keep them from blowing onto your plant or away!

Insects. Some plants are just more susceptible to insects than others. And when it’s this hot and dry, all plants are more vulnerable to bugs and the diseases they can transmit. Keeping an eye on your plants, even with a stroll through your yard or garden after dinner, can help you spot problems. Keeping plants watered and free of as much stress as possible also helps.

basil-leaves
The leaves are the “fruit” of a basil plant. We have to take extra care to protect ours.

Others, like basil, are favorites of lots of insects. Since the leaves the insects attack are the part of the plant we eat, I keep my basil covered with a light row cover cloth that lets in air, sunlight and some water, but keeps out as many leaf eaters as possible.

basil-leaf-damage
Some tiny beetles still snuck under the basil cover and damaged early leaves.

Other critters. The tender leaves and ground-level placement of seedlings are also more vulnerable to attack. I’ve seen the leaves of new cucumbers or flowers decimated by grasshoppers and more often, by snails. The slimy acrobats even climb up into containers and eat plants as soon as they come up. We use egg shells as the best deterrent we can find, but there also are snail baits for bad infestations.

fencing-lathe-ground
Gopher fencing below, deer fence above. But the squirrel got in.

Below-ground fencing can deter gophers and other underground tunnelers, but that requires fencing a few feet underground around all plants. We reserve that fun task for our vegetable garden only. Then, despite those efforts, a squirrel has come through the fence and made giant holes in our garden. He has not damaged any plants yet, but I have a feeling it’s coming. We have had some luck spraying Animal Stopper small animal repellent around some plants to deter squirrels.

deer-garden-snow
I could tell this deer was eyeing my rose bushes. Not so bad in winter, but they ate all the plant’s blooms in May and June. Notice the 5-gallon buckets around other plants for warmth and some deer deterrent.

Our deer are grazing much longer into summer this year and have destroyed all the bloom stalks on our native and hybrid roses. You have to be pretty desperate to eat something that thorny on a regular basis. We’ve had some luck with Animal Stopper deer spray, but the only way to ensure deer stay off plants is to fence them out.

shade-structure-cloth-tomatoes
My husband rigged PVC pipe on one side of our tomato bed to hold shade cloth. You can find lots of ideas for inexpensive plant protection from neighbors and social media.

Look to your neighbors, master gardeners and landscapers for more local strategies to help you keep plants alive during rough patches. And practice patience.

 

Santolina: You Can Grow That!

gray-santolina-yellow-blooms
The bright yellow blooms and silvery foliage of gray santollina.

Santolina is an herb said to be used in folk medicine to make a tea that expelled intestinal worms or was used as an eye wash. The plant repels insects, and placing leaves in sachets is said to repel moths.

We grow santolina (also known as lavender cotton) in our rock garden for its evergreen appearance, yellow button-like flowers and drought tolerance. It’s not native to North America, but does very well in our dry Southwest soil.

gray-santolina-foliage
The silvery-green, almost lacy foliage of gray santolina up close.

Gray santolina (Santolina chamaecyparissus) produces bright yellow flowers in summer. The plant has few matches for attractive gray-green foliage and its ability to spread as a groundcover. Our large one has been a cover for a litter of cottontails and is now spreading slowly over a rock wall.

gray-santolina-pruned-rock-garden
New growth on a gray santolina (right after spring pruning) cascading down a rock wall.

Another variety, green santolina (S. virens or S. rosmarinifolia) has lemon-colored button flowers that contrast with its deeper green foliage. Both types of santolina have an aroma, and some people find the bloom aroma offensive. Most varieties of the shrubby groundcover grow in zones 5 through 9 and need only moderate water. Learn more about santolina varieties from Cornell University.

lemon-colored-blooms-green-santolina
I love the lemondrop look of the green santolina flowers.

Caring for Santolina Plants

The plants prefer full sun, but our largest santolina blooms each summer even though it now gets lots of afternoon shade from a nearby tree. Place the plant in well-draining soil. When temperatures reach 90 degrees, water your santolina every few weeks if you get no rain. Otherwise, it needs water only monthly or less.

green-santolina-before-gopher-spurge
Even before blooming, green santolina is a nice companion for the light green foliage of gopher spurge.

Prune (really, shear) santolina shrubs in early spring to shape and remove dead flower stems. Every two to three years, give the plant a harder prune down to about 6 inches above the ground to keep the plant from getting leggy. You also can sheer dying flower stalks after the first bloom for the chance of a second summer flowering.

green-santolina-not-pruned-enough
I did not prune this plant low enough a few years ago, and it is a little leggy and less rounded. Still, it has an attractive, natural shape.

The plant is evergreen or semi-evergreen in some climates. Santolina does best with no fertilizing. How easy is that? And you can take cuttings or divide larger portions of the plant in fall, although the transplants might succumb to cold, so if you can warm them the first winter, even better.

Whether you grow santolina for its herbal properties or appearance, you can grow that!

 

5 Easy Plants for Xeric Gardens

Xeric plants are smart, easy-care choices simply because they need little watering once established. Still, I’m sure some people avoid trying new plants, or opt for mostly gravel, to lessen time needed caring for ornamental plants.

desert-zinnia-chimenea-pot-with-lobelia
Desert zinnia adorns this low-water rock garden.

I’ve got five great options for Southwest gardeners, each hardy in our zone 6B garden and during summer heat. Although all are not technically xeric, they can thrive with little to no watering other than rain. Mostly, these plants need very little care, so try something new this year!

Yarrow

moonshine-yarrow-blooms-leaves
Moonshine yarrow is easy to care for, transplant and grow in low-water gardens.

Yarrow (Achillea sp). Yarrow is an herb, and a close relative of chamomile. Yarrow is said to aid digestion or heal wounds when applied as a pulp. Take a look at the scientific name (ever heard of Achilles and his heel?) and you can see how many years people have used yarrow for medicinal purposes. Achilles is said to have applied yarrow tinctures to heal and prevent wounds.

moonshine-yarrow-blooms-closeup
Here’s a closer look at yarrow blooms. Pollinators love them as landing pads.

I grow yarrow because it’s pretty, attracts pollinators, and is one of the easiest perennials to maintain. Technically, yarrow needs a little more water than other low-water plants when summer temperatures hover at 90 degrees and higher, but our plants have made it through many seasons with one spring watering and natural rain after that. They’re hardy in zones 5 through 8. You can cut the spent blooms off to encourage more flowering. But for easy care, leave them on the plant, especially in cooler regions. or cut them back all at once for a second bloom in warmer climates. When trimming, you’ll probably see some tiny flowers close to the leaves that should shoot up and open. We’ve transplanted several yarrow plants with no trouble.

Ornamental Grasses

In windy areas, ornamental grasses stun in the garden. We often place them as single plants in a grouping of others, but I love the look of a row or grouping of the same grass in the landscape. Even those that aren’t native tend to need less water than some plants, since they don’t truly flower, but can produce lovely stalks topped with seeds. And you can mix textures, colors and heights for landscape interest. There are so many choices!

karl-forester-feather-reed-grass
Karl Foerster Feather Reed Grass (Calamagrostis acutiflora Karl Foerster) in our dry river bed in midsummer.

Even those grasses that aren’t native need little care and use little water. A few (like Silky threadgrass) can spread, but you only need to pull or dig up the tiny starts in early spring to control where they grow. We like to add one annual such as Purple Fountain Grass (Pennisetum secateum ‘Rubrum’) each year for color pop, but our other grasses make it through winter.

purple-fountain-grass-seeds
The flower stalks of Purple Fountain Grass.

Just check to see average zones. For example, the Purple Fountain Grass can overwinter in zones 8 through 11. And ask whether your favorite is a warm-season or cool-season grass; that helps you know when to plant it and whether it will survive winter or need a little shade in the heat of summer. All you have to do is shear back the foliage each spring as the grass begins to green at the base. So, so easy.

Prairie Zinnia

desert-zinnia-blooms-foliage
Prairie or desert zinnia spreads easily in sunny, dry locations.

Prairie or desert zinnia (Zinnia grandiflora), is an easy and attractive groundcover with sunny yellow flowers that grows in zones 4 through 9. The plant is native to New Mexico, Arizona and parts of southern Colorado, so it’s hardy in Southwestern soils and survives drought. Ours were already in our garden, and I have heard that the plant can be a little challenging to get started. My guess is excited gardeners plant the zinnias too soon, before soils have warmed. Ours cascade down a rock wall, coming up each year in little soil, but plenty of warmth from the rocks. The rocky soil also drains well, which likely helps keep the plants healthy and spreading at just the right rate (not invasive). The foliage browns in winter, but is so small it doesn’t look messy. All I do each year is put on my gloves and gently pull away the dead foliage when I see it greening up at the bottom. Once you do that, the plants get the sun they need and begin growing and flowering.

Gopher Spurge

closeup-gopher-spurge-stalk
The foliage stalks of gopher spurge are attractive all year long.

Gopher spurges (Euphorbia rigida) are among few plants that handle extreme cold (down to -20 degrees) and the high heat of zone 11. The plant is called gopher spurge because it has been said to repeal gophers, but I’m not sure there is any proof of that, or anything at all that truly repels the underground destroyers. I can say that ours have survived, save some deer chomping. The stalks that were eaten succumbed to cold, but I just cut them off at the base of the plant.

euphorbia-blooms-yellow-red
Gopher spurge blooms early in our zone 6B xeric garden. This is in March.

Otherwise, our gopher spurge has grown nearly a foot in one year and was among the earliest flowering plants in our spring garden. We also have a Euphorbia ‘Ascot Rainbow’ we bought locally last year, and the foliage alone is beautiful. This newer plant also has survived winter and is beginning to bud out. All you have to do is cut off stems after the seeds ripen; new stalks will come up and you can enjoy the silver-green or colorful rainbow foliage all year. Gopher spurge and many other Euphorbias are succulents, so they’re lovers of sun, heat and low water.

Coreopsis

It’s the year of the Coreopsis! And I’m so glad. The native flowering plant is so versatile. It looks beautiful in rock gardens or more formal landscapes. Just place coreopsis in well-draining soil and most perennial varieties should be hardy from zones 4 through 9. Sometimes called tickseed, coreopsis comes in several varieties and deer seem to ignore the plants. Because the native plants tend to come  up along ditch banks or other disturbed areas they tend to easily grow in any Southwest garden conditions. The bright yellow blooms of Lanceleaf and Grandiflora coreopsis are common, and breeders have grown new varieties of Coreopsis with color variations.

lanceleaf-coreopsis-sterntaler-blooms
Tickseed (Coreopsis lanceolata Sterntaler) blooms all summer with a little deadheading or shearing.

Deadheading flowers as they dry up will keep them blooming, but if you find deadheading takes too much time, wait until a good flush of blooms has begun to die back and shear the flower stalks off all at once; you should get more blooms.

Hooked on Worm Castings

My husband’s got worms and I couldn’t be more thrilled. Because his worms eat food scraps and produce a nectar-like waste product – worm castings.

worms in feeding tray
Our worms have produced rich compost — and more worms!

With vermicomposting, he’s producing a soil amendment (humus) full of more than 60 micronutrients and trace minerals to gently and naturally support plant growth. Worm castings are the excrement left by worms, and the worm tower he uses for vermicomposting makes it easy to feed the worms and harvest their castings.

Benefits of Worm Castings

  • Castings hold all sorts of live micronutrients that help plants better absorb nutrients from soil, especially soil with low or high pH.
  • The worm castings can help repel some pests such as white flies and aphids; an enzyme in the castings is offensive to pests.
  • Feeding worms food scraps reduces and recycles garbage throughout the year.
  • Worm castings do not stink!

How a Worm Bin Works

worm-factory-bin
A Nature’s Footprint Worm Factory has trays with levels to feed worms and make compost.

Tim purchased a Worm Factory from Nature’s Footprint a few years ago. He keeps it in a corner of the garage for easy access and protection. Vermicomposting works with upward migration. The worms move up to eat, and gravity sends moisture and castings to the bottom. Adding food at the top every so often (when worms are actively eating the last food you added and are moving to the top tray) keeps the worms continuously fed and reproducing. The worms eat paper, fruit and vegetable scraps, bread, coffee grounds and eggshells, along with other scraps. The bedding added to each level eventually breaks down into castings as well.

worm-bin-food-tray
The food tray with bedding sits on top and worms move up to eat.

The resulting compost is thick, dark and crumbly. Its ready to use as soon as you harvest. Some of the best uses are to mix the castings in with garden soil as an amendment or to top dress container plants. We added castings to some of our vegetable starts last year a few weeks after planting, just loosely scratching the castings into the soil around the plants. It takes less worm compost to improve soil than regular compost.  Finally, use worm castings to make compost tea.

worm-castings-harvest-to-bucket
We now have nearly 3 gallons of worm compost in this bucket. A fitted lid keeps it airtight.

A Few Tips

Keep the tower warm in winter. You might have to either move a worm bin or give it some heat. There are insulators made for bins. Tim hangs a lamp over the bin and sets a timer so the lamp warms the bin at night. Even if production slows, the worms are warm enough, and the food does not freeze.

worm-bin-under-light
Tim keeps the worm bin inside the garage with a light on a timer for winter warmth.

You’ll have more success if you break the food scraps into manageable sizes, about the size you get when running a peeler over a carrot.

Be sure to check instructions for worm type. Red wigglers (Elsenia festida) eat and reproduce better than most, but you can use European nightcrawlers (E. Hortensis), which work well in our tower.

harvesting-worm-castings
Once he emptied this layer of worm castings, he placed the empty tray on the bottom of the bin.

Store your worm castings in an airtight container and they’ll continue to break down. Just let the castings dry a little before sealing. They can be damp but not wet.

The leachate, or liquid that runs down, can be toxic. Don‘t use it if it smells bad or on edibles. Be sure to dilute it with a ratio of about 10 parts water to one part leachate.

If you’re looking for a way to get kids involved in gardening, worms are it! What fun kids can have helping care for the worms and seeing how they help a family grow food or pretty flowers for mom. It’s also a great way to teach responsibility if kids are charged with prepping scraps or bedding and feeding worms.

sifting-compost-worms
We returned worms still in the castings tray to the food tray and sifted out large bits of food or paper, leaving a rich compost.

If you can’t spend the money on a worm bin or tower, you can find information on making your own or vermicomposting directly into a garden bed.

10 More Gardening Terms Explained

Last fall, I listed and defined 10 gardening terms that you’ll see often in books and blogs about gardening. I’ve got 10 more to cover just before gardeners start buying new seeds and plants and planning their 2018 gardens.

gardening basics
Gardening can be easy, and knowing what terms experts use can help you have success.

10. Zone

A zone is the climate-related gardening region in which you live. The most common designation that likely appears on your plant tags or care information is the USDA hardiness zone. It’s based mainly on how cold your lowest lows fall in winter. A zone in the Southwest can match one on the East coast, but other conditions such as temperature extremes in the day, soil makeup, wind or humidity also can affect how well a plant grows. New Mexico has 10 variations of the USDA zones, from the mountains’ 4b (slightly warmer than 4a) to 9a along the southern Rio Grande valley. Learn more about USDA and Sunset zones here.

mountains of new mexico
In the Sacramento Mountains outside Ruidoso, N.M, we saw some plants we can grow in the valley below, but the zones change rapidly.

9. Root-bound

Plants for sale or that you’ve placed in a container can become root-bound. This means the roots couldn’t spread outward as the plant grew, so they began circling the container borders and might be poking out of drainage holes on the bottom. Most plants grow poorly and can even die when this happens, but see this article about house plants that like crowded root conditions. If a root-bound plant for sale looks otherwise healthy, you can take a chance on it. Break up the roots with your fingers and spread the roots out when you plant in the ground or in a larger container. Be sure to check for signs of circling roots on indoor and outdoor container plants.

adenuim in pot
This gorgeous adenium can handle being root bound and does best when not planted too deeply.

8. Heirloom

When we sell tomatoes at market, we get plenty of requests for heirloom varieties. These grow from older, more pure seed lines handed down for generations. They’re often some of the tastiest and most nutritious vegetables you can find. Ambitious gardeners prefer heirlooms so they can save their own seeds for planting the next year. However, they might not resist disease as well as a tomato variety bred to do so, and heirloom varieties like Brandywine don’t do well in shorter growing seasons like ours. Still, every gardener should try an heirloom flower or vegetable at some point to enjoy the benefits of the carefully selected qualities bred into the plants.

Blue Lake green bean heirloom
We’ve continued to plant Blue Lake heirloom beans every year. The plants do well and the beans are crisp and delicious.

7. Hybrid

When breeders create hybrids of any plant, they control the results by selecting favored qualities of both plants and cross-pollinate them to produce a new plant with the best of each. The careful controlling of the process by breeders can take years of care. Hybrids give us vegetables resistant to diseases, with richer colors or flavors or that produce in shorter growing seasons. Hybrids are not the same as GMOs; genetically modified plants are developed by altering DNA in a lab.

6. Crown

This is the part of any plant where the roots and stem join. See this demonstration for placing the crown at the right depth from Fox Hill Gardens. This is important because the crown should be just about soil level when planting most plants. Be sure to check instructions that come with individual plants, especially roses and trees, about depth of planting and whether to mulch to help protect the crown.

5. Seed start

A seed start is the small plant, or seedling, you grow from a seed. New gardeners can be confused about whether they can plant a seed directly in the ground (direct sow, below) or whether the plant will do better started indoors under grow lights and then transplanted into the garden at the appropriate time. You can save money starting seeds, and basil and zinnias are two easy annual plants to start from seed. Others, such as cucumbers, don’t transplant well. This article from Gardener’s Supply Company has great advice on starting seeds, which can help save money on new plants each spring.

Last spring’s seed starts under grow lights. We started herbs, vegetables, and perennial and annual flowers.
snapdragons
Check out these snapdragons grown from that flat of flower starts. And they lasted into fall, at least until deer ate them.

4. Direct sow

This means to place seeds directly into the ground in the garden or in a container. Carrots, lettuce and green beans are easy vegetables to grow from direct sowing. Just follow the directions on the packet about seeding time, planting depth and spacing. You might have to thin your seedlings later. One positive: if you plant too soon or too deeply, seeds cost so little you can often try again!

3. Determinate

The tomato terms determinate and indeterminate have caused me plenty of confusion in years past. I don’t know why I have such a hard time remembering them. Determinate varieties grow to a set mature size and produce most of the fruit within a few weeks. Then it’s done. Determinates also are called bush varieties.

indeterminate tomato in container
Often, determinate, or bushy, tomatoes do best in containers. But we also grow indeterminates, which need cages for support.

2. Indeterminate

These tomatoes continue growing until hit by frost, and sometimes are called vining tomatoes. They produce fruit steadily through the growing season, depending on weather conditions, etc. They can grow out of control if not staked. I’m planning to remember the difference by noting that indeterminate implies the plant does what it wants. But I wish someone would invent a better set of words!

plant growth habit
Varying growth habit adds interest to a xeric garden.

1. Habit

Basically, a plant’s habit refers to the direction it grows, such as upright, mounded or prostrate (spreading low along the ground). It also refers to terms such as shrub vs tree. A shrub, for example, grows to only about 15 feet high and has multiple stems in the ground, whereas a tree usually has a single trunk and greater height. This handout from the University of Colorado shows growth habit shapes and definitions.

 

 

10 Fall Chores in the Garden

As fall temperatures drop, there’s still plenty to do in the Southwest garden. In most areas of New Mexico, freeze hits by mid- to late October. But plenty of sunny days hit in fall here so gardeners can get outside and take care of these chores before winter arrives:

Raking up gorgeous fall leaves is just one fall chore outdoors.

1. Harvest

If you still have any vegetables ripening, better harvest them now. Tomatoes and winter squashes can finish ripening inside. If you haven’t harvested and dried herbs, now is the time to trim them back and get them ready for use in the kitchen. Some vegetables, such as kale and carrots, can stay in the ground a while. You can preserve some vegetables with help from extension office publications or other credible sources that address flavor and safety of canned or frozen foods. Finally, I like to pick flowers still blooming and place them in a vase inside, just to make me feel better about the season ending.

2. Clean

There is some debate about what to leave in the garden and what to throw out. You definitely want to throw out any weeds or diseased plant cuttings. Compost healthy cuttings. We even laid some carrots that were too big for our taste out on tree stumps for deer and other critters to eat. It’s personal preference to leave some debris on the ground to naturally compost in place. But if the debris hides unwanted bugs or spores, it’s not a good idea. I usually clean up most plant debris and then use straw or leaves for composting.

3. Preserve Bulbs and Seeds

Check a local gardening book or online to find out how to dig up and overwinter bulbs that can’t handle cold temperatures in your area. In zone 6B in New Mexico, we leave iris, daylily and allium bulbs or corms and should dig up gladiolas and dahlias. Usually, the bulbs just need to be kept cool and dry. You also can preserve seeds from flowers and herbs such as dill or cilantro for cooking or replanting.

These gladiola flowers added color and attracted pollinators (but were safe from deer) in our vegetable garden. I’ll dig them up soon to winter them over inside.

4. Leave Some Seeds

Not all flowering plants need fall trimming of spent seed heads. Many can make it through winter and wait for summer trims. And birds love dried up seeds on sunflowers, cosmos and other flowering annuals. Plus, by leaving the seeds on, you increase the chance that some native grasses or flowers will reseed.

5. Evaluate Plant Placement

As you clean up and assess how plants look at the end of their growing season, you can evaluate plant placement. For example, some of our green beans did not fare as well as last year. I believe the spot I planted them in this year got more late summer shade from a neighbor’s tree than I anticipated based on early summer sun. Some plants might have grown too large for their spot or get too much water from runoff. Take some notes and consult local sources so you still have time to decide whether you can move them this fall. Or plan where they’ll go in spring, especially before buying new plants!

6. Mulch

In New Mexico, we mulch for two reasons: to conserve water and cool roots in summer and to warm roots during cold winter. I typically mulch as part of fall cleanup and near the time of the first freeze. Most plants that are native and appropriate for your garden can get by without mulch, but it helps protect tender plants from hard freezes in winter. Mulching needs to be a few inches thick to insulate and to cut down on weeds.

7. Protect Plants

Some of my gladiola bulbs came back and rebloomed without being dug up. But I mulched them pretty heavily with leaves. In addition to mulching, you can put buckets around plants to help keep them warm, especially in winter wind, or to keep deer from destroying them (adding a “lid” made of chicken wire or similar material that lets in sun and moisture but not curious critters). Plants in containers that are tender or annual in your area need to come inside, We move outside containers against a south-facing wall for warmth and to protect against wind.

8. Empty Containers

It’s time to empty all those containers with edibles and annuals that are dying back. You’ll need fresh potting soil next year and it’s better to store containers empty. We empty soil from our containers (unless the plant had a disease) into garden beds and large stock tank containers that need soil. You can also save potting mix in plastic sealed containers, but it should be mixed with fresh potting soil and compost when replanted in the spring.

9. Amend Soil

If you have new garden beds or some that need better soil, fall is a good time to improve soil health. Adding some compost gives it a chance to break down, as does covering beds with leaves that fall from trees. And it makes the spring preparation easier. There are many ways to amend bad soil, such as planting cover crops before frost or having a soil test so you know how to better balance pH in your growing beds. But gardeners learn to tell when soil is compacted. It’s hard to go wrong adding a little organic matter in fall.

10. Enjoy Time Outside!

Fall is a favorite season for a reason. Cool nights and warm days make it hard to stay inside, even when there are few chores to do. And enjoying even the final flower blooms before frost arrives is part of the reason you work hard to make your lawn and garden look nice.

Five Easy Foods to Grow at Home

It’s warming up outside (finally!) and lots of Southwest homeowners will be planning changes or additions to their xeric and edible gardens.

easy grow vegetables
Three easy vegetables to grow at home: cucumbers, tomatoes and green beans.

1. Small tomatoes – cocktail, cherry, grape
Pros: Tomatoes are by far the best crop to grow at home to enjoy the flavor and quality of the fruit. Small tomatoes ripen in most climates, and if you plant in succession (such as one plant every two weeks), you can enjoy them all summer in moderate climates. Colorful cherry tomato varieties look terrific roasted or in salads. And these smaller tomato varieties can grow right on your patio in a container (minimum about 12 inches).
Cons: Heirloom tomatoes are  pretty and often large, plus great for slicing to add to sandwiches and green chile cheeseburgers. But unless you live in a warmer zone (Las Cruces, Deming and lower elevations of Arizona), or have a greenhouse, it can be tough to grow large heirloom tomatoes. At zone 6B, we have a relatively short growing period.

Care: Tomatoes need sun and heat; larger fruit seldom ripens completely if temperatures drop or clouds roll in at the end of the summer. It’s possible to keep tomato plants going, and we probably could have grown larger varieties last year. Look for short-season varieties. Water tomatoes consistently for best results, using a timed drip system when possible and a routine for hand watering containers.

2. Cucumbers
Pros: When you grow your own cucumbers, they’re fresher, tastier and lack the wax coating applied to commercial cucumbers. They’re easy to grow and typically produce for months each summer. You can find burpless, slicing and pickling varieties. Cucumber flowers are bright and pretty, so the plant can look great mixed in with ornamentals.
Cons: A cucumber plant needs lots of space, and should have a trellis or similar structure for climbing. You can grow one in a container, as long as you have something for the plant to climb on or around or choose a bush variety (they take 2 to 3 feet of space vs. 6 feet for vine plants).

Cucumbers can grow on patios if given a place to climb.

Care: Plant cucumber seeds directly in the ground based on seed packet instructions for your zone. Cucumbers don’t transplant well and don’t germinate well until the ground and air are warm enough. Learn when to harvest for best flavor and smaller seeds, usually before the fruit gets larger than its stated size. Give them full sun and well-drained soil.

3. Green beans
Pros: Green beans come in bush or pole (climbing) varieties, along with filet shape, are super easy to grow and are pretty plants. Snap beans (with an edible pod), shelling beans, and dry beans are all choices for home gardeners. You can find purple beans and other colors to liven up the kitchen garden and your dinner plate. Green beans grow well in a range of zones.
Cons: Beans can produce! Although you can freeze or can extras, you can become overwhelmed by the harvest. Plant beans several weeks apart to extend the season and grow only what you need. And be sure to provide stakes, tee pees or fencing for pole beans.

Green bean plant
Green beans have delicate white flowers and are fun to harvest.

Care: Sow seeds directly in the ground in full sun when possible and after the soil warms. Beans need well-drained soil and regular moisture. There is no need to soak bean seeds before planting; the plants germinate quickly and soaking can damage bean seeds. Beans do best when temperatures are not too high (above 90 degrees F) or too cool.

4. Snap peas
Pros: Snap peas are my new favorite vegetable to eat right off the vine. Sugar snaps are delicious raw and a great addition to salads, vegetable trays or stir fry. You can start pea plants earlier than green beans, as soon as soil temperatures warm to about 45 degrees F. The peas grow best in cool weather, which makes them perfect for early spring and late summer planting. The flowers are pretty and delicate, and the leaves are more attractive than larger green bean foliage.
Cons: Sugar snaps have annoying strings along the entire pod, but you can find stringless varieties. The plants need more water than some vegetables.

Sugar snap pea seeds go right in the ground in spring.

Care: If using a drip system for your kitchen garden, add a few extra emitters or more pressure for your peas. Vining varieties do best if supported by a trellis or other structure. Mulching around the base of the plants helps keep them cool and moist.

5. Carrots
Pros: Every child (and adult) should get to pull and taste a fresh carrot to get hooked on vegetables. Carrots do well in cool weather, and are one of the first crops you can plant in spring (about 3 weeks before your last frost). Often, you can keep them going well into fall or winter with the help of a row cover fabric or similar method to warm the ground slightly. Carrots come in a rainbow of colors or several sizes and shapes of typical orange roots.
Cons: Carrots require thinning to grow best, and it’s hard to pull up any of your many seedlings. But thinning helps – this is a root crop and you want the root to have plenty of room beneath the soil. If your soil is too compacted, the carrots won’t grow well.

Care: Keep seeds evenly moist and be sure to thin when leaves reach a couple of inches high. Until ready to harvest, keep the crowns covered with soil. Harvest carrots when the top of the root, or crown, is under an inch in diameter, depending on the variety.
