Favorite Xeric Plant: Lavender

It smells fantastic, looks gorgeous, attracts bees and butterflies and needs little water or care. And on top of that, it’s a useful herb. Truly, I can find no drawback to growing lavender in the arid Southwest. Still, I’ve talked to several people while selling at farmers’ markets who say they had trouble establishing or maintaining lavender. So, here are a few tips, because I wouldn’t mind seeing lavender on every corner of every town.

Where to plant lavender

It’s tempting to plant lavender everywhere in the landscape! But the plant does best in full sun and with plenty of air circulation. So, if you plant lavender on the north side of your house, especially up against the house, it might not do well. You can also plant lavender in containers, but might have to amend soil around the plant after a year or two. Be sure to place the container in full sun and give the container plant a little more water than it would need in the ground — but not too much!

Lavender hedges are a summer stunner. But if you want to plant a row of lavender, be sure to leave plenty of spacing between the plants, and between the lavender and other plants or structures in your garden. It won’t look as full the first year. But by year two, you’ll love how the flower stems nearly touch but the plants have plenty of room. And foremost, plant lavender where you can enjoy the scent and pollinators the plant attracts. And check nurseries soon for a new variety from Sunset called “Meerlo,” which has variegated leaves!

When to plant lavender

Whatever date you think is right for lavender, push it back a week. Seriously, the only real problem we had with some lavender plants occurred when a group of new plants were shipped to us too far ahead of our last frost date. Fearing the plants were becoming rootbound in their small nursery pots, I planted as soon as the frost passed. But the ground and air were still a little too cool, plus the dirt did not drain as well as other spots in our garden. So that meant the new plants would stay wet after rain or watering. The only problem that really affects lavender is root rot. So be sure the ground and temperature have warmed up enough before planting.

Lavender looks and smells pretty close up or from a distance, especially in a breeze.

How to plant lavender

First, make sure the variety of lavender you’re ordered or chosen at a nursery is a perennial in your area. Years ago, I assumed that French lavender (which really is from Spain) would do better in our climate than English lavender. It’s so cool and damp there! But French lavender is not as cold hardy. Most varieties of English lavender, however, can survive U.S. winters. Just check the zone when you buy.

Here’s the trick to success with lavender: Plant it on a small mound. This is a departure from typical attempts to save water by welling around plants. A well can hold water in longer, but lavender wants to take a drink and then dry out. Also, by gathering up a mound of dirt, you give the young roots some nice loose soil.

new lavender plant
This new lavender plant is becoming well established. It’s on a small mound to keep water or snow from pooling around the roots. The next step is to add pebble mulch.

My second tip is to surround your lavender not with organic mulches, but with tiny white pebbles or decomposed granite. Doing so still allows water to penetrate, but gives the plants reflected sun and passive solar heat gain. If you use rocks and have as many weeds as we have, you’ll need to try and get the mulch layer at least three inches high. But leave a border several inches around the new plant on every side so the rocks don’t crowd the lavender base and constrict growth. Water more often than the plant tag says for a few weeks or more, until the plants look settled in their new home. But let new lavender plants dry out a little between watering or rain.

How to care for lavender

So, you have your lavender established. The hard part’s done! All you have to do how is harvest the gorgeous flower stems as the flowers begin to open in summer. In warmer climates, you often get a second bloom. We’ve found that our second bloom in zone 6B is pretty sporadic, even lousy. So it’s really a matter of choice – you can harvest early and enjoy the scent inside your home, or leave the stems on the plant to enjoy its color and share its fragrance with pollinators.

Just be sure to trim the stems off – right at the top of the leaves – at the end of summer or in early fall. Don’t worry if your plant turns a little gray in winter; it should begin to green up along with other perennial plants in spring. As new leaves begin to emerge in spring, trim your plant for shape and health. That means avoiding cutting down into the woody stems. I give mine a nice round shape. So simple.

Our lavender wands and sachets have been popular this year.

That second year, your plant should need little to no watering. I typically give lavender plants some water right after trimming in spring and then only water if we have severe drought.

The stems are easy to dry and place in a vase or use harvested buds to make sachets or potpourri. Lavender is great in homemade gifts and even as an edible.

Late Summer Garden Problems? Don’t Give Up

It would be fun to see a chart of gardener enthusiasm from May through September. My guess is that it would look something like this:

summer-garden-dont-give-up (11 of 1)

After all, gardening can take time and effort, and summer vacations, heat, family time or work all interfere. It’s easy to get discouraged when bugs and weeds take over and plants don’t look their best. This morning, I had to water for the first time in weeks following a period of regular rain. It took all the effort I could muster, especially since most of our time is spent controlling insects and weeding, usually the same spots over and over again.

low-water southwest garden midsummer
Some people might see a lush low-water garden. I see weeds that need pulling, flowers that need deadheading, beds that need mulching and even a bird bath that needs water!

Then I came inside and remembered: So maybe the horn worm stripped about a fifth of the leaves from one of our tomatoes? At least we finally got control. The plant doesn’t look its best, but the tomatoes are ripening. If we don’t get as many as planned, I can live with that. I can’t just let the plant go, which wastes all of the time, attention and water put into getting it this far.

Staying positive can be tough, but here are seven tips for getting past midsummer doldrums in the garden:

Don’t consider problems as failures. Plants naturally begin to decline and leaves yellow in midsummer. Vegetables and some ornamentals are annuals, after all, and go through a seasonal life cycle. Plus, your plant is putting more energy into fruit or flower production than forming perfect green leaves. And you really can’t control the weather, but only help your plant through rough periods such as drought.

We nearly pulled this tomato up because the leaves have looked awful since an early heat wave. But we're getting some gorgeous roma tomatoes!

Take some photos and share them. You might see brown leaves on a fading green bean plant, but others might see how high the plant has gotten. A close-up of the bean or bloom, along with blooms on flowering ornamentals, focuses your own attention on the beauty that you’re nourishing. Likewise, a photo of your entire garden compared to how it looked two months ago should represent the pride of the work you and nature accomplished.

Change your routine. Although it’s always best to water in the morning, sometimes it’s more fun to go out to breakfast first. Spending time in the garden still is important, especially as plants get crowded, which gives insects more places to hide. If it’s too much to water before work, add a timer to a drip system. Spend time pulling weeds and checking for insects in evening just before the light fades. Or make it a family activity a few days a week.

Share your harvest. Everybody gets tired of zucchini. I love harvesting fresh vegetables early in the season, but my enthusiasm tends to wane when every plant is at peak production. I’m more jazzed this year because we’re selling most of our crops at a farmers’ market. Home gardeners can share with colleagues, neighbors, family members or food pantries. Your enthusiasm is sure to rise when work friends comment on how delicious your fresh cucumbers taste.

Take a tip from nature. Often, birds spend more time in the garden as flowers seed out and fade. The birds don’t care if the plant is a little leggy or faded. They still appreciate the seeds, especially if they’re migrating. Really, would you rather be trapped indoors in winter than out here tending your garden? Picture fewer weeds next spring because you got to the ones in the garden now before they seeded out. You can save yourself some time next year by keeping up now.

Keep notes and plan strategies. Gladiolas deer resistant? I think not. I’ve grown some gladiolas as this year’s splurge in terms of water because they are a perfect cut flower. And yes, I should have cut some stalks and brought them inside before last night. The newest flowers and buds are gone, thanks to a deer with discriminating taste who left the fading flowers alone. I’ll have to change where I grow the bulbs next year or keep up with deterrent sprays and methods. I’m looking into doing a better job with trap crops for insect control. And we’ll choose the plants for our microfarm that do the best in our typical conditions (if there is such a thing) and that people like to purchase the most. Plan now, while problems are fresh in your memory, for fall and spring planting.

Scrutinize social media posts. Obviously, don’t ignore everything on social media. But anyone who posts photos of perfect plants and huge flowers isn’t including photos of the plants they had to pull up because of disease or the really weedy area of their garden. It’s especially important to ignore posts like “How to Yield 300 Tomatoes From One Plant.” First, that’s just to get you to click through. Why compare yourself, and besides, do you really need 300 tomatoes? Lastly, it’s probably not the best advice around. Look for real, solid and credible information and set realistic expectations for yourself and your plants.

Finally, enjoy reading a book in the shade after you’ve worked in the garden, maybe while munching a fresh cucumber. It will be more relaxing!

 

Diagnose and Prevent Drought Stress in Plants

A droopy, wilting plant. It’s a gardener’s instinct to automatically assume: It needs water. And sometimes, that’s a good instinct. But low-water plants just as easily can be killed by kindness as by neglect.

gladiola
Gladiolas like an inch of water a week, but not too much water.

For example, several problems with tomato fruits are caused by too much water, or especially irregular watering. Plants, like people, need some regular hydration. You wouldn’t avoid drinking water for five days and then gulp down a liter, right? One reason drip systems are effective is the consistency (assuming you set a timer) of the amount of water they deliver, along with the slow rate of flow and the fact that they water the soil/roots and not a plant’s leaves. The delivery and slow flow help retain more moisture and nutrients around the roots.

What’s the prognosis?

There are reasons other than drought stress that cause plants to wilt, including problems with the roots. That’s why plants you’ve just transplanted from seed or a nursery container tend to wilt for a few days or weeks. The roots suffer some damage when taken from a pot and replanted. Understand that this is part of the natural course of the plant’s life and help it through without stressing too much (meaning you, not the plant). Even though a plant is waterwise, it still needs extra water until the roots heal and begin to grow, more efficiently pulling water into the plant. If the ground is dry at root level, the roots can’t do their work. Plants that are overwatered sometimes wilt, too, further complicating the “diagnosis.”

tomato branch broke water
After our first heavy rain, I accidentally brushed against a branch of this currant tomato.It peeled off; the brown leaves are likely from that damage, not from lack of water!

Speaking of, most gardeners jump to the worst possible scenario when determining a plant problem. Although disease is a possibility, look not only for symptoms of a particular wilt or fungal disease, but also for possible causes. Do you have evidence of bugs that might have damaged leaves or carried a disease to your plant? Is the plant getting enough air circulation? Is water running off and away from the plant? Has it just been super hot for several days?

incipient wilt
Incipient wilt on a squash. Still not the best scenario and a signal to check our soil, but it’s temporary.

The best way to distinguish drought stress from other causes of wilt is by looking at and feeling the soil. Damp soil means the plant has water available; adding water at this point likely won’t help. You should feel an inch or two below the surface. One way is to stick your finger in the dirt to about the first knuckle joint.

Prevent plant stress

When a plant needs water, it’s more susceptible to damage from bugs and diseases. Pests attack the weak. You can prevent plant stress from underwatering by:

  • Checking the soil as mentioned above; see if there is water for the plant.
  • Looking for signs of underwatering. These usually include leaves turning yellow and brown, and even falling off. Typically, drought stress begins with lower leaves.
  • Thinking about the plant’s environment and how it might have changed. Is it windy and hot or muggy and cool in the evenings? Did you last water a plant in the afternoon out of necessity instead of your usual morning routine?
hot day on plant
Not much you can do about these weather conditions within a week or so of placing new plants in your landscape. Water consistently in the morning and shade plants if practical.
  • Using a meter or records when in doubt. We have an inexpensive moisture meter for our farm area. If nothing else, it helps confirm or deny my suspicions about the need to water and gives me a basis for comparing soils or drip rates around certain plants. Keeping records of watering, fertilizing and other activities can help manage and diagnose plant problems.
water meter to check moisture
Geraniums like to dry a little between watering. An inexpensive meter might not be the most accurate tool, but can help a home gardener check soil moisture.
  • It’s always better to water before a plant wilts, and not to wait until wilting occurs. Although plant roots need to seek water, they also have to find it! When no water is available in the soil around them, plants can begin reacting with wilt, slowed growth or flower and fruit production, and other signs.
xeric bush spirea
Blue mist spirea is a low-water plant. If the leaves have spots, it’s more likely getting too much water than not enough.
  • Finally, remember there is no hard and fast rule on watering. Much of the advice I see comes from areas that are more humid, cooler, less windy, and at lower altitude than our conditions here in New Mexico. Having said that, you can create conditions that help plants retain moisture, mostly by ensuring healthy soil and mulching. Containers need a little more frequent watering because they dry out faster than the ground. Water container and landscape plants slowly so the moisture drips instead of flooding down. You probably only need to add water to a container when the top few inches of soil are dry.

 

 

Six Money-saving Tips for Home Gardeners

Getting started gardening requires some upfront investment, but you can have a nice garden or lawn and stay on budget with a few simple tips. Here are some ideas we use to save money:

Gardening might cost a little to get started, but not if you reuse and repurpose. Perennial plants last, and some re-seed year after year.

Repurpose containers. Sure, I partly mean to re-use the same pots year after year. But I also mean to look for found objects and turn them into containers. Buckets and pails make great containers, for example. Just drill one or more holes in the bottom for drainage. Old metal baskets also look really cool for hanging plants. But they will need lining with moss or cocoa fibers to help control water. Choose your material based on how much water you want to remain in the basket.

When re-using pots from previous years, be sure to empty dirt out in the fall and wash the container then and/or before planting again in the spring.

Grow food. Save money and even water by incorporating food into your landscape. Fruit trees double as shade trees as they mature, which can lower energy costs. Growing just one or two vegetables that you purchase regularly at the grocery store can save money on your food bill with the minimal investment of a plant and soil.

Use household or found items. Whether for garden art and interest, staking a plant or shading a new transplant, don’t be afraid to get creative with items you already have. A garden should be a retreat for you and your family and reflect your taste and comfort. I’m not suggesting you place eyesores in your front lawn, but household and kitchen items can be really useful in the garden. We re-use buckets and pieces of fencing to warm plants or keep deer off. Lots of kitchen items are touted for garden uses. Eggshells might not stop snails altogether, but the crunchy shells might cause them to detour at least. Coffee grounds have some use, but see this handout for a scientific look at their effectiveness.  At the very least, add them to your compost.

These new plants wilted from the heat yesterday, so we got out the lawn chairs. I know it looks funny, but it's in the back yard and temporary. The chairs give filtered shade, but allow air to circulate. And I put a few yard staples in them to keep the wind from blowing them away (or onto the plants).

The chairs give filtered shade, but allow air to circulate. And I put a few yard staples in them to keep the wind from blowing them away (or onto the plants).

Compost. Worms really love coffee grounds, and if you decide to start creating vermicompost (worm castings), hold on to the coffee grounds and newspapers! Making your own garden compost (without housing worms) is another easy and inexpensive garden improvement. Check online for plenty of plans and ideas for homemade compost bins or buckets. Just be sure to also research what can and can’t go into the pile (I keep a cheat sheet near the sink) and how to keep the compost fresh, damp and turned.

This compost bin is right by the garden, and we have a wooden one closer to the kitchen.

Save seeds or divide plants. Saving seeds from spent flowers is a great money saver for next year. You can keep seeds in simple zipped plastic bags, as long as you store them in a cool, dark spot. If saving seeds for vegetables, you’ll have better luck if you only save seeds from heirloom varieties, or purchase a new packet every few years. Seeds do not cost much at all. We divide or move plants to fill empty spots in our garden, and you can likely find a friend, neighbor or coworker willing to trade your iris bulbs for his daylilies.

Choose perennials. Perennial plants come back year after year; their life span depends on the plant and conditions (such as a really hard freeze). Perennials cost a little more from a nursery, but since they return, you save money the following year. That’s assuming that you water the plant a little more heavily than its instructions say until it seems well established in your garden and place it in the right conditions (zone, sun, etc.). Just ask for a little help from local nursery staff or experienced gardeners; they love telling you about their favorite plants.

You can fill a few bare spots with annuals, especially from seed, and including annual herbs for your kitchen or flowers you can cut and use for arrangements. All it takes is a little planning and ingenuity to grow what you love and on a budget.

Mix Up Your Garden Palette

Our low-water garden has lots of yellow. Maybe that’s true everywhere. And it’s a bright, happy color. But we like a little more variety, and it’s easy to add pops of color a little at a time, or with annual plants. Here are a few tips for finding plants of many colors.

yellow blooms
Yellow flowers like the ones on this chocolate flower plant (Berlandiera lyrata) are gorgeous, but I like to mix it up.

When the butterfly bush blooms, we’ll have deep purple, red, and yellow. I’m adding a few low annuals to the front corner, which is closest to the patio.

Find flowers by color

Although you’re used to a favorite flower blooming in a particular color, there likely are hybrids with colors you hadn’t considered. For example, we think of sunflowers as bright yellow, but I love the cinnamon varieties. I’ve got some seeds in again, in the hopes that bugs and deer leave them alone.

larkspur pink lilac
Larkspur grow wild in our garden, and although most are a deep violet, we also have lilac, white and pink flowers.

One way to find flowers in complementary colors is by using apps and online databases. For example, the LadyBird Johnson Wildflowercenter’s database includes bloom color, along with native states and sun and moisture requirements in its combination search. For a simpler search, try a list like the one maintained by ProFlowers, which lists flowers by color next to illustrations and a brief description. Just beware that national lists of flowers often include varieties that do poorly in some zones or soils or need more water than those in a xeric garden. Be sure to read the descriptions or do a little research before making your final decision. You can also try apps that either have pictures shared by posters or plant identification. If you can find a local or regional app, even better.

Wander around a nursery

If you feel a national list might isn’t giving you enough choices for your area, visit a locally owned nursery. Although they’ll carry some annual varieties that aren’t perfect for the community’s climate, they also carry plenty of knowledge and tend to feature plants that are native or adapted to local growing. If you do find a few annuals either at a local or chain nursery, limiting the number to a few pots or a corner of a bed uses less water, time and money than basing your garden color plan on annuals. Most nurseries separate perennials and annuals to help shoppers.

Bringing home the plants from our local nursery. I got a few annuals to add more red, white and black to our garden. And sometimes, the foliage adds lots of color, like with my new barberry.

Make notes as you pass homes and businesses

If you’re walking to a restaurant in town one night and spot a flower with a color you love or know would add variety to your garden, take a photo of the plant and a close-up of the flower. This will help you compare what you saw (and photos work much better than memory) with identification apps, databases and local gardening books. Including the entire plant in the photo helps you remember the type of foliage, height and spread of the flowering ornamental.

Color really is a matter of personal choice, and with the recent National Pollinator Week in mind, I try to choose a few new plants for their ability to attract bees, butterflies or birds. For example, studies have shown that bees gather more nectar from purple or violet flowers than from any other color.

Keep it simple and choose what you like, but remember not all plants bloom at the same time, so your color variety might be seasonal or in stages. That’s great too though, so you and the pollinators can enjoy some new blooms every few weeks.

Bees really go nuts in cactus blooms.

Favorite Xeric Plant: Gaura

Some call it a butterfly plant. That’s because gaura has delicate, swirly flowers at the ends of long stalks that resemble butterflies. In fact, one variety of gaura (G. lindheimeri) is called ‘Whirling Butterflies.’ It has white flowers; ‘Siskiyou Pink’ blooms have an earthy pink tone. And in 2014, Gaura ‘Sparkle White’ was an All-America Selections National Winner.

Typically, eight stamens jut out from the delicate flower up long stems. No wonder gauras bring butterflies to mind.

We’re fortunate enough to have wild or native gauras (G. coccinea) in our garden. They appear on their own in late spring and bloom as temperatures warm. They’re a little more like a weed, partly because of the places they tend to appear, and partly because they have a higher foliage-to-flower ratio. Still, I’ll take them, and so will the bees!

Drought tolerant gaura

Native gauras appear along roadsides and other dry areas. Many of ours come up through rocks in the garden wall. You don’t have to read a plant tag to know that a plant growing robustly in rocks needs little to no water. We’ve had some trouble with gaura from nurseries, and I believe the reason is that the soil we chose was compacted and holding too much water. Still, if you plant a new gaura, it will need watering until healthy and established. A drip system can give the plant a slow drink.

Easy care

Once you’ve chosen a sandy or loamy soil for your plant, place it where it can get full sun. By the second year, you won’t have to water except maybe once in spring or in severe drought. I really love to place the white flowers where I can see them from a window or patio. It’s also a great plant for breezy areas, holding up to wind, which causes the flowers to “dance.” Most gauras reach about 2.5 to 3 feet tall; the native  varieties are a little shorter.

gaura against rocks
Gauras look terrific in rock gardens and natural designs.

Cut G. lindheimeri back in early spring about halfway down the foliage to keep it bushy, full and not too leggy. I let the native gauras go to seed so they pop up again the next year. You can try the same with nursery varieties; the plant might self-sow if seedheads remain in autumn. The only pests that bother gauras are flea beetles and gardeners who overwater them, especially if the plants are in heavy soil.

Versatile plant

Gauras are hardy in zones 5 through 8. In colder zones, the plant can be damaged if wet when temperatures dip to more than -15 Fahrenheit. Gaura is considered a perennial in those zones, but tends not to last as long as some hardy perennials.

gaura and gaillardia
These volunteer, or native, gauras popped up with volunteer gaillardias. I love the combination.

The gaura can fit into nearly any landscape design. Even before blooming, its slightly mottled leaves provide garden interest. I love to see it against a slightly taller plant with larger, bolder flowers (which also can support the gaura stems as the plant matures). Gaura also is perfect near steps, garden paths and walls. Although gaura fits perfectly in a natural xeric design, its delicate flowers can work in a cottage garden plan, provided it’s not overwatered or has really good drainage. Native gaura foliage and shape is not as stunning, but nonetheless a fun re-seeder in a naturalized xeric garden.

 

 

Purslane and Portulaca

I’ve grown to accept that some invasive plants (aka: weeds) are not so bad. I’m still on the fence with purslane (Portulaca oleracea), a prostrate spreading succulent that can take over entire flower beds.

portulaca flower
Ornamental portulaca from the same family as purslane. Note the ornamental’s thinner, needle-like leaves.

Weed or edible?

Purslane can grow in pavement, between rocks, and in moist conditions. It spreads from seed or from pieces of stems. And a purslane can have more than 50,000 seeds per plant. It re-roots after being hoed. That’s a weed, right? Still, many value purslane because it is edible. But in my mind, if the plant interferes with the objectives in managing a lawn or garden, it’s a weed. And since mats of purslane suck moisture and nutrients from soil and even shade soil from sun as they spread, they’re pretty much weeds in my book. That’s especially true in a vegetable garden, where I don’t want a weed competing for precious water.

purslane weed
Purslane taking over a rock garden. It’s best to pull it up before it gets this big, whether you eat it or throw it out.

Purslane was grown in India originally and provided nutrition and reported health benefits. Those who eat purslane have described its taste as lemony or similar to spinach. And the plant tastes best if “harvested” while its fleshy leaves still are young. So one way to eradicate common purslane where you don’t like it is to follow the philosophy “If you can’t beat ‘em, eat ‘em.”

You can spot common purslane as a small seedling with reddish-tinged leaves that form flat against the ground and spread out like spokes in a wheel. Pull it up before it sets seed to avoid having an entire bed full of the weed the next year. Not sure a weed is purslane? Check out these photos of seedlings and other stages of purslane from Missouri State University.

Ornamental value

Even common purslane can be pretty. The fleshy leaves contrast nicely with tiny, usually orange, flowers. And I bought one years ago before I knew better. I paid for that, because the plant came back with a vengeance, choking out other plants in a tiny rock garden. So if you choose to actually plant purslane as an edible, just beware that you’re introducing the seeds to your landscape.

heat loving drought tolerant portulaca
Portulaca is a great container plant. Use one color or mix many. The plant spreads and cascades slightly over the edge.

A better alternative is an ornamental portulaca such as P. grandiflora. You can tell an ornamental portulaca from a purslane by its leaves. Ornamental portulaca, often called moss rose, has more needle-like leaves than purslane foliage. The flowers also are showier, often looking either like a cactus bloom or a tiny carnation or rose. The best part? They love sun and heat, are highly drought tolerant, and will spread in warm climates to make an interesting groundcover. They’re also a perfect container plant, especially if you buy a mix of colors, which warm-climate nurseries usually carry. Both purslane and portulaca bloom in the morning after the sun has been up a few hours, and close later in the day.

Portulaca just planted in the ground. I hope they will cascade over these rocks and pavers and re-seed next year.

Caring for portulacas

Portulaca is an annual, but can re-seed. Although not nearly as invasive as its purslane relative, an ornamental portulaca often pops up somewhere in the landscape. But to me, it’s a happy surprise. The easy-care, drought tolerant annual is welcome in our garden any time temperatures begin to warm up in early summer.

Portulaca actually do better with sun and heat, but who would have thought it would be 40 degrees F in mid-May? I can’t wait for these containers at the back of our garden to fill in.

Portulaca will keep blooming and spreading into fall, provided you do one thing: pinch off spent blooms. If you let most of the faded blooms remain on the stem, the plant can become leggy, plus it won’t bloom as often. The equivalent of deadheading this annual is so simple; just pinch the blooms off into your hand after they have closed up and begun to look withered. If the flower resists, wait a day. You’ll soon recognize the difference between a bud and a spent bloom.

This portulaca re-seeded in some soil we repurposed for one of Tim’s cacti. It just goes to show how little water they need! You can see the bloom stages really well in this photo. A tiny dried-up flower peeks from behind the bloom; it’s ready to pinch off! Two new buds are a little lower on either side of the stem. And a faded bloom, nearly ready to pinch, lies at the lower right.

And if you want to pinch your portulaca while eating a salad with purslane leaves, that’s up to you. Just be armed with new recipes to cook up all of your purslane in years that follow.

Not Just Another Iris Farm

Yesterday, I joined two friends on a perfect trip to the nearby Hondo Iris Farm, on Hwy 70 about 20 miles east of Ruidoso. Each year, it’s such a joy to see the irises in full bloom around Mother’s Day and to wish that I could purchase nearly every color and type of iris I see.

But I considered as we walked around yesterday that the Hondo Iris Farm is more than a striking display of irises. It’s a local botanical garden, shop, nursery and perfect place for a picnic! My friends brought delicious food and we ate on a lower picnic table closer to the valley. A group of ladies gathered for their own spring picnic at a table right next to the rows of iris.

The Hondo Valley runs along the Hondo River (Rio Hondo), which begins where the Rio Ruidoso and Rio Bonito rivers merge. The Rio Hondo runs nearly 80 miles, where it feeds the Pecos River just outside Roswell. The valley is bordered by mountains and has witnessed the history of Native Americans, homesteaders, Billy the Kid and lawmen, and was once a rich farming area with large apple orchards.

Pruning Xeric Plants

The best part of early spring is watching growth appear on plants that have been dormant all winter. And since we can’t plant vegetables until after the last frost, I need something to do in the garden on nice spring days. We had two of those this weekend, and we got busy pruning our xeric garden and front beds.

Pruning woody lavender requires only some shaping and removal of stalks as or after they bloom.

Pruning can be scary for new or hesitant gardeners. I’ve often hated to cut off any of the new spring growth that’s already begun. But I have to remind myself that cutting a plant back saves water. Here’s why: The plant’s roots can only provide so much water and nutrients. If gardeners leave too many branches above ground, the roots struggle to feed every branch, leaf or flower all the way to the end of the plant. It’s like filling a bowl of cereal with milk. The more cereal in the bowl, the more milk is necessary to coat or soak the cereal (sorry, but I love food analogies).

This butterfly bush looks like mostly sticks right now, but it’s loaded with new growth at the bottom.

I’m still having to remind myself that by cutting a plant further down, I actually help it grow more vigorously than if I merely trim it a little bit. The mature plant regrows to a size that matches its established root system. We cut several plants nearly to the ground, including Russian sage (Perovskia atriplicifolia) and butterfly bush (Buddleia). I have yet to kill a plant from vigorous pruning. A few times (like with forsythia), I pruned at the wrong time and it affected shape or flowering. But you can always correct shape and learn from your mistakes.

Here’s last year’s butterfly bush (to the right and center) after a similar prune last year. It shoots up to six to eight feet tall.

Around here, Tim typically trims the trees and I handle shrubs. I start with roses as soon as any new growth appears, and your local master gardeners most likely recommend a window of time that’s best for roses and other common plants in your area.

Here are a few pruning tips for plants that grow in the arid high desert and intermountain regions:

  • In early spring, prune plants that flower in summer. Those that bloom in spring (like forsythia, clematis, flowering quince and dogwood) do best if pruned after they flower. They form buds in the fall, and spring pruning removes the flowers. The same goes for spring-flowering bulbs, such as iris, although they shouldn’t be pruned immediately, but when stalks and leaves begin fading or turning brown. In this case, the plant above ground gives energy back to the bulb underground.
forsythia blooms
Our forsythias are loaded with spring blooms; I pruned them last summer.
  • Nearly all trees should be trimmed in winter, while dormant.
  • Some gardeners prefer to prune in fall for a more manicured look during winter. We don’t do that for a few reasons. One is that a late warm period can cause the plants to grow again, and they need to begin storing energy for winter; a heavy late pruning can make the plant more vulnerable to cold. The other reason is that birds feed on the flower heads all fall and winter. And the spent blooms and stalks look fine in a natural, xeric design.
yarrow blooms

  • Many plants only need to have their dead stalks removed. For example, yarrow and Angelita daisies have stalks that rise above the foliage. You can use trimmers or sharp shears to remove spent stalks.

Here’s what the yarrow looked like a few days ago. It was ready to lose the dried flower stalks.

The pruned yarrow is now ready to put energy toward developing new flower stalks.
  • It’s best to avoid cutting into the woody, feeder branches of plants such as lavender and rosemary. Trim them for shaping only, and harvest ends of rosemary or cut lavender flower stalks for drying and other uses.
  • The more center and crossing canes or branches you can remove, the better. If you have a native rose that is seriously overgrown or pruned poorly, consider cutting it to the ground once, just to reinvigorate the plant and let it return to a more natural shape. It might take a year or two to get the plant into the shape you like.

I’m gradually cleaning up this native rose. Last year, it bloomed so pretty in mid-April. This year, I pruned it more severely, but it’s taking on new growth.
  • Some plants do better with a second cutting right after they bloom so you can enjoy another summer show of color. An example is catmint (Nepeta). Shearing off about one-third of the plant at the top gives it energy to regrow flowers. Of course, many annuals, such as California poppies (Eschscholzia californica) or blanket flowers (Gaillardia) bloom best if you deadhead them, or remove spent blooms, throughout the summer.
Our catmint was already blooming and attracting bees by the time I got to it. But it's so forgiving (and at times invasive here). I pruned off dried stalks and shaped the plants for a wilder look around the path's rock border.

  • We usually give our xeric plants a good soaking right after trimming them to help them through the shock and stimulate growth. But that’s the only time we water almost all of our established xeric plants.
dogwood and catmint
Best of both seasons. The dogwood still has its winter red, but plants like catmint are blooming.

Five Low-water Plants for Use in the Home

It’s one thing to enjoy the look or scent of a plant and its flowers; it’s a bonus when the plant rewards the gardener with other uses. And to me, any plant that attracts pollinators and people is a useful one. Some plants do more, however, doubling as edible, decorative or medicinal plants for the home. Here are five plants with home uses that also survive low-water or drought conditions once established.

Bees, butterflies, and most people love lavender. And deer don’t like them, so we can grow them anywhere we like.

Lavender

Lavender (lavandula) seems to be tops on any plant list I compose. I’ve yet to meet anyone who doesn’t care for the scent, and bees and butterflies flock to the flower stems. And the flowers – you can cut them for arrangements, dry them to make gifts and even use buds in recipes. Lavender is touted for its soothing qualities for skin and stress, as well as its aroma. The plants are easy to care for in a low-water garden. Simply give them well-draining soil so the roots dry between rain or watering. Harvest the first flush of flower stalks and you’ll likely have another bloom in late summer. Otherwise, trim only to shape in spring.

Lavender buds are easy to harvest once dry. They’re perfect for sachets and soaps as easy homemade gifts.

Thyme

Another favorite low-water herb is thyme. Just touching it gives your hand a salty, earthy scent. You can cut entire stalks in the fall for drying, or cut a fresh sprig for flavoring poultry. It’s an excellent herb for flavoring vegetables with strong flavors, such as cabbage. Tiny purple flowers emerge on longer stems that haven’t been harvested, attracting bees and adding delicate color to a xeric garden. German thyme is hardy in zones 5 through 9, but lemon thyme needs a little more heat (zones 7 through 9). Just give thyme plenty of sun and well-drained soil and it will spread, creating a low bushy appearance in the garden.

Thyme is a perfect xeric evergreen and a yummy herb. Last fall, I dried thyme, oregano and sage stalks for use in the kitchen.

Sea holly

Sea holly (Eryngium amethystinum) has a thistle-like appearance to me. The drought-tolerant flower is a perfect choice for rock gardens, or even sandy beach gardens. That’s because it loves hot, dry conditions. Big Blue reaches heights or nearly three feet. The stunning silver-blue flowers are spiny in texture. Use sea holly indoors by cutting a few flower stalks to include in arrangements. Not many other cut flowers have their color, texture or unique look. Sea holly grows in zones 2 through 10.

Aloe vera

Got sunburn? Fresh gel from your own aloe vera plant (Aloe barbadensis) can provide soothing relief for burns and skin rashes. Of course, sunburns are more likely to occur in areas where you can grow aloe vera plants outside, like Maui, where we used aloe to soothe our tourist “color.” So, it’s an outside plant only in about zone 10B, or where night temperatures go no lower than 40 degrees F. Aloe vera also needs well-draining, even dry soil. The plant stores water in its fleshy leaves, which makes the well-known gel. If you’re in most zones, you can grow aloe vera as a houseplant and summer outdoor visitor. When you need to extract gel, you can use simple kitchen items. Here’s an article explaining how to get gel from aloe leaves.

Pineapple guava

Growing nut and fruit trees for shade and food is a smart xeric gardening strategy. Of course, you have to pick the right tree or shrub. The pineapple guava (Feijoa or Acca sellowiana) is an excellent example of a tree that bears juicy, full fruits but with less water than some fruit trees. These aren’t like truly tropical guavas, but have a taste that resembles a mix of pear and pineapple. The plant is drought tolerant but a little more water ensures late summer to fall fruit. And even if they don’t fruit much, the gorgeous white and red flowers look good enough to eat. It’s too cold in New Mexico, but southern California gardeners can enjoy the plant and its fruit. In fact, we spotted a guava in the lawn of a Pasadena home. I was too busy being jealous to take a photo. Here’s a photo and more information on the plant from Monrovia.
