Spring has come early to New Mexico this year. We’re been breaking records for high temperatures. That’s been so nice and has really improved my mood. I’ll even consider it lucky, since we have lots to accomplish before summer.
Of course, our average last frost is around May 10, and April 15 in Albuquerque. So I fear all of the pretty flowers on the fruit trees will freeze at the worst possible time. Or that my impatience with cleaning up and lightly pruning xeric perennials will backfire. I choose to remain optimistic.
Enjoy these green (and a few other colors) early spring finds. Just click on any thumbnail to start the slide show.
Growing with organic methods is smart for lots of reasons, both personal and environmental. Although there are plenty of strategies gardeners and homeowners can use to save water with ornamentals, such as planting native and xeric plants, it’s a little tougher with vegetable gardening.
Tomatoes, for example, need consistent watering! But growing tomatoes organically can conserve water. Here are five ways how:
Organic soil retains water better. Anyone can improve their soil’s water retention by up to 5 percent by adding organic matter. It also helps to avoid use of chemicals and pesticides. Using pesticides and chemical fertilizers in gardens can throw off the natural balance of the soil, making it less able to retain moisture around plant roots and making fewer nutrients available for plants. On the contrary, planting cover crops in the fall and use of compost or other organic matter help restore valuable soil nutrients. Organic matter also helps soil structure for water infiltration and retention. Healthy soil can respond better to drought conditions.
Organic growing protects water supplies. By avoiding chemical pesticides and fertilizers, gardeners also protect the water supply. Pesticide chemicals can remain in the soil for years; some are more toxic than others and break down in the soil more slowly. The chemicals from these products can run off into bodies of water, such as rivers. And eventually, they can seep into groundwater. That might seem a distant concern to some urban gardeners, but those of us using wells live right above available water. The more chemicals that run into water supplies, the less safe drinking water is available.
Use of mulch reduces evaporation. A layer of appropriate mulch above the ground around a plant helps reduce ground-to-air evaporation, making the soil take longer to dry out. The mulch also helps cools plant roots. Using organic mulches such as bark, nut shells, compost and others adds organic matter to the soil slowly over time for an added bonus.
Organic methods can minimize erosion. Traditional gardening and farming uses rototilling and deep plowing to turn the soil before each growing season. Plowing deeply and turning the soil over can disrupt soil microorganisms, harm soil health, and place looser soils on top, where they’re subject to erosion from water and wind (think Dust Bowl). No-till methods help control erosion and build soil structure. The soils, in turn, better retain water. This can be a problem if the soil drains poorly, but a definite help in low-water regions. Not tilling involves building up beds with organic matter, much like nature does as plants drop leaves that decompose. If you want to work organic matter in, it’s best to grab a shovel. A broadfork is the best tool for breaking up compacted soil.
Growing organically creates healthier plants. Healthy soil is the foundation needed to grow healthy food. When soil has good nutrients and structure, it supports root growth and uptake of nutrients, improving plant health. Plants that are not healthy are more vulnerable to insect and disease damage. The plant might not use water as it should when it’s stressed, and the gardener certainly guesses that if a plant looks bad, it needs water. So, keeping plants healthy saves the extra water the plant needs or gardener applies in times of stress. And healthy plants keep on going, so you don’t waste water on establishing a plant that later dies from poor conditions.
Native plants should be the mantra of every xeric gardener. Let’s first review what makes a plant native and why native plants are so beneficial.
What is a Native Plant?
A native plant grows naturally in a particular region or location. To be termed “native,” a plant must have had no human intervention when it first set down roots. That doesn’t mean you can’t plant natives, just that the original plants were, well, original to a region and not introduced. The benefits of choosing native plants are many, including:
Water savings. Plants native to a region and climate should need less water from gardeners in prairies and mountains, relying mostly on Mother Nature alone. Even in areas where drought is less of a concern, native plants should get by on typical rainfall with little supplemental watering after the first year or so.
Convenience. Less watering means less time, in addition to the natural and financial resource savings! Native plants should be easier to maintain as well.
Helping pollinators. As natural areas such as forests and prairies disappear, usually because of development, bees and butterflies have fewer plants they can rely on for the energy they need. Planting natives helps them find nearby food sources. Attracting pollinators always is a good thing – they help tomatoes and other vegetable plants fruit, and your garden improves their habitat. Regardless of the many “right” reasons, you and your family can enjoy watching bees, butterflies and birds as the pollinators enjoy the buffet.
Better chance for success. Native plants are adaptable, so if you plant the right plant in the right location and follow care instructions, watering a little more than recommended in the first season or so, your job is easy after that.
Native Plant Resources
Now that I’ve convinced you to go native, where do you find native and pollinator plants for your region? Here are six resources:
Your local nursery, as in locally owned. You’ll find more knowledgeable staff on average here than at big box stores (such as Walmart or Home Depot). Local nurseries tend to grow and sell plants native to your area, and usually can answer your questions, even with some specifics on microclimates in your region. Catalogs that sell to your region or zone also can be helpful, especially in identifying pollinators (typically with an icon of a bee, butterfly or hummingbird).
Apps, especially from local sources. There are some great plant apps or mobile-friendly sites, including GrowIt! And Plants Map. For example, GrowIt! has a search feature for plants within a set radius of your location. As long as there are other members near you, it can be a big help. Plants Map includes communities, resources and individuals in its collections. A search could bring up your nearby botanical garden or private collections. Local apps from trusted sources such as extension offices are great for spotting natives. I use Southwest Plant Selector app, listed on my Resources page. In the future, watch for Leafsnap, a collective effort to offer visual recognition software to help you identify plants, much like a printed field guide.
USDA Plant Database. The Department of Agriculture has a database from which visitors can search plants by scientific or common name, and filter by state. It also has a state plants checklist (that looks like HTML code, unfortunately). This site is not sexy, but the best part about it is that once you find a plant you’re considering, a map comes up that indicates whether a plant is native to your state (green fill). It includes a lot of scientific information, but most plants have several photos to help verify identification and if you click on “legal status,” you can learn whether the plant is considered endangered or classified as a noxious weed in your state.
Native plant societies. The North American Native Plant Society has lots of information on natives, including a database searchable by type of habitat and this list of state plant societies. Those state groups with websites or newsletters can be excellent sources, and most offer inexpensive membership.
Friends, family and neighbors. If you see a plant you like, one full or butterflies, or remember a favorite from childhood, ask around. Even if a plant is not native, but seems to do well in your neighborhood, you can ask the homeowner or a local landscape designer about ease of care and hardiness.
Native Seed Resources
Growing natives and pollinator plants from seeds is less expensive, but can require a little more time and water initially. Here are a few sources for information on gathering or buying native seeds:
Xerces Society- In addition to pollinator plant lists for the United States (that unfortunately appear to exclude New Mexico, Arizona, Colorado and some other Western states), the society has a seed mix calculator to help with restoration efforts of prairies, etc., with native pollinator plants.
The North American Native Plant Society also has a seed exchange for members and information on collecting seeds from native plants.
Native Seeds/SEARCH is the top source for Southwestern native seeds. Their vault contains native crop seeds for low desert and high desert regions, along with wildflower seeds. It’s a wonderful combination of conservation and native seed resources.
Check out the Resources page for more information on buying seeds and plants native to your region.
Often on this site, I talk about how to keep gardening simple, fun and useful. And although xeriscaping can be tricky and drought even tougher to endure when starting out as a gardener, there are plenty of strategies to help gardeners succeed, or at least enjoy the process.
To help Southwest gardeners — and all people jumping into gardening — I try to follow a few important rules:
Here’s how I look at it: We all started out new to this hobby at some point, whether it was in childhood or following an education in horticulture. Yet we’ve had nursery people talk down to us when we ask a question, and I cringe every time I see a tweet or pin titled “You’re Doing _____ Wrong,” or “5 Mistakes to Avoid With ____.”
I’ve also seen fellow master gardeners try so hard to show what they’ve learned that they are condescending when talking to new gardeners on social media or in person. That’s really the opposite of the concept; master gardeners are trained to help.
To that end, I recently wrote an article for Green Profit Magazine about how folks in the industry can talk to the level of all gardeners and potential gardeners. The article includes some helpful sources who recognize that helping gardeners succeed beats telling them what they’re doing wrong.
If someone kindly explains something to me that I already know, it wastes a little bit of my time, but I appreciate the effort. But when someone makes me feel stupid because of a question or error, I simply stop frequenting their business or acquaintance.
So, if you already garden and want to recruit a neighbor, daughter or friend into the hobby or you communicate with gardeners, help people with kindness, example, simplicity and patience.
It’s warming up outside (finally!) and lots of Southwest homeowners will be planning changes or additions to their xeric and edible gardens.
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).
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.
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.
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.
I tend to hibernate in winter, and emerge only on days that are sunny (common), not windy (rare) and warmer than normal for this time of year (sporadic). I get why animals do the same, and I love the thought that I’m helping them get through winter in some small way.
Here are a few ideas for helping area birds and wildlife with your landscape:
Deer have their own diet, thank you
Animal lovers feel empathy for wildlife when severe weather hits, leading to cold and scarcity of plants the animals browse. Unfortunately, tourists in mountain communities appear to be more interested in taking selfies with wildlife. We live near a resort town, where small herds of deer and elk (and bears) live in or enter populated areas. I’ve seen tourists pull over and feed deer. I don’t even want to know what they are feeding the animals. It’s also likely that some people in wildlife areas put out feeders to attract deer. But I don’t agree with that for several reasons.
Ups and downs of feeders
First, deer take time to adjust to new foods, many of which are not easily digested by wild animals. The kitchen scraps or Doritos from a car window can do more harm than good. Even if a homeowner sets out a feeder with pellets designed for the deer diet, doing so changes browsing and movement patterns and makes it easier for predators to find and prey on herds. The deer also can depend on humans or compete more for concentrated food sources, which means the weak ones lose out at a feeder. In open areas with natural food sources, the fawns and young bucks can find nearby sources when kicked off the favored spots.
We live in a residential area with large lots and our deer are not as used to people as those a few miles up the road. I like it that way, and instead of feeding them, we leave our grass longer in fall to help with their browsing (and we believe it helps improve native grass coverage the next spring). We also do our best not to bother the herd by walking slowly and away from them if possible when sharing space outdoors. That also means teaching our dogs to ignore them.
I have wondered and worried why deer don’t come around when we have a blanket of snow on the ground, but I thought it might be too difficult to get to the food below. That is true, and deer know to fatten up and live off reserves, staying close to their trees up higher for shelter. Coming down to graze through a layer or snow would take more energy than the payoff. Other wildlife shelter ideas are piles of dead tree limbs away from the house and in protected areas, along with fencing that is easy for deer and elk to enter.
Feeding birds in winter
We do supplement birds’ diets in winter, and although I will continue doing so, I see some evidence of the same problems that can occur at deer feeders. First, hawks and kestrels come right into the garden, hunting near the feeders. They would help me and themselves more by finding some yummy mice to eat instead. Second, we see some feeder competition at times, but we have several different feeders/types of food, and for the most part, the birds all play well together. Placing feeders at different spots and filling them with different energy sources can support more types of birds, especially during migration.
Natural food and shelter
Of course, natural food sources are great for birds too. But by late winter, the stores of berries, nuts, and seeds on flowers, trees and bushes has dwindled. As I wrote about this time last year, birds need extra food in winter to gather energy to fight cold. And many, such as juncos, must replenish that energy daily in cold weather.
Plants also provide shelter, and placing both shelter and food sources at various heights and spots in your garden offers some protection. Here are some bird-friendly plants:
Flowers for seeds, including sunflowers, Echinacea (coneflower), coreopsis, salvias, and many native grasses and annuals. Milkweed (Asclepias) not only helps Monarch butterflies, but attracts plenty of insects that birds eat.
Fruiting vines and shrubs such as Virginia creeper (Pathenocissus quinqefolia), wild grapes, elderberry (Sambucus) and serviceberry (Amalanchier utahensis Koehne, or Utah serviceberry),
Native trees for fruits, nuts and shelter. Birds need a high place to land when escaping or looking for predators. Evergreens such as arborvitae (Thuja occidentalis) and all spruces offer dense shelter from the elements for landing or nesting.
These plants also can provide winter interest for homeowners’ gardens and can feed birds through fall and early winter in some cases.
I’ll admit that part of my willingness to also spend the money on bird seed is selfish. It’s nice to watch the bird show from our window when the plants are dormant and I’m stuck inside. But I also like to think that the shelter and food our place provides help ease the burden for these and other creatures.
Each year various societies present plant awards, but those of us who garden in the West and Southwest await the group of Plant Select top performers. Plant Select, which is a nonprofit joint effort of Colorado State University in Ft. Collins, the Denver Botanic Gardens and professional horticulturalists, lists five top performers at various elevations.
First, a word about why the work of Plant Select and other regional groups is so important. As I said, there are plenty of awards and lots of information in the gardening world. But, for the most part, plants emphasized by magazines and bloggers are great for East Coast and Southeastern region gardeners. It’s different in the high plains and intermountain areas of the country, where altitude, wind, and heat and cold extremes (in a single day and by season) affect plant health. And let’s not forget the water issue.
Plant Select evaluates plant performance in 53 locations throughout five Western states. Here are some of the 2016 Top Performers. See the entire list at Plant Select.
Grand Winner: Blonde Ambition Grama Grass
Blonde Ambition grama (Bouteloua gracilis ‘Blonde Ambition’ PP22,048) was introduced by New Mexico’s David Salman of High Country Gardens (American Meadows). Blue grama is a perfect low-water native grass grazed on by cattle on our Southwest ranches. Salman introduced the blonde ornamental variety in 2011, and this is the second year it has been Plant Select’s grand winner. Beginning in July, chartreuse blooms (seedheads) appear on upright stems, turning to the blonde color as they age. Watching those seedheads wave in winter winds provides xeric gardeners some year-round interest in their landscapes. Although Blonde Ambition can spread by seed, the seedlings are easily pulled up. The grass is hardy in zones 4 through 9 and deer resistant.
Top Performer at 3,000 to 5,500 Feet Elevation
Blonde Ambition also tops the list of lower elevation garden performers in the region. Number 2 on the list is a tree I’ve never grown, but want to learn more about since it also topped the list for gardens at my altitude (6,300 feet). The Hot Wings Tatarian maple (Acer tataricum ‘Gar ann’PP15,023) has bright red samaras, or fruit made of paper tissue, that bloom all summer. It’s also known for its reddish-purple fall color. The Tartarian maple is a relatively small tree, maturing to nearly 18 feet high and wide, and gets by with full sun and moderate to dry water needs. The only drawback for me is that it is not deer resistant, but I could see this gorgeous tree in any suburban garden from 3,000 to 7,000 feet in elevation and in zones 4 through 10. We still might try it, but we’ll have to fence the tree until it reaches a mature height and keep lower limbs pruned.
Top Performer at 5,501 to 7,000 Feet elevation
Although the Hot Wings maple topped the list of performers at this elevation, I would like to give a nod to No. 2 on the list – Turkish veronica (Veronica liwanensis). Veronica is an excellent low-water groundcover. Veronica is evergreen, so it covers portions of our rock garden all year long. In summer, the groundcover blooms. Turkish veronica has cobalt blue flowers above waxy leaves. It only reaches about 2 inches in height, but can spread to 18 inches wide. Although veronica is a xeric plant, its leaves look better with a little extra water in the heat of summer. Turkish veronica is hardy in zones 3 through 10 and deer resistant. The top 5 Plant Select performers at this elevation also include Blonde Ambition, Apache plume and a catmint called Little Trudy (Nepeta ‘Psfike’ PP18,904).
Top Performer in Gardens Higher than 7,000 Feet
Fernbush (Chamaebatiaria millefolium) topped the list for higher elevations. The Western native shrub is xeric once established and grows more upright with less water. It can look more formal with rounded pruning in early winter. Deadheading spent flowers also makes the plant look neater, and should be pleasant considering that the foliage has a honey-like scent. The sweet scent also deters deer. Fernbush can grow to nearly 5 feet high and wide; less water keeps it more compact. The plant thrives in full or partial sun in zones 4B through 8.
These are only a few of the top performers in the Plant Select list. Check out their site for more on current and past top performers, new plant introductions for the region and where to buy plants for High Plains and Intermountain gardens.
Succulents are low-care starter plants for anyone easing into gardening or short on space. Best of all, they’re typically the lowest water users of the plant world. It’s often said that cacti and succulents thrive on neglect. Although that might be true when it comes to maintenance such as trimming or fertilizing, cacti and succulents do need a little attention and consistent, light watering.
The common characteristic of succulents is that they have adapted to surviving with little water. Cacti are tough, and about the only thing that will kill them (other than being munched or trampled by wildlife) is overwatering. In general, about once a week is perfect. Set a date every Saturday morning, for instance, to water and check on indoor succulents. The best way to water container succulents is by making two trips – water your succulents once with a slow, steady stream. Don’t give them so much water that it runs out the bottom of the container, but give them enough to soak in past the surface. Then come back and give them a second drink, which makes for a deeper and more even watering.
The best watering for outdoor succulents is through a steady drip. How much depends on conditions, just like with other plants. When heat is extreme, cacti and succulents need a little more water. When it rains, you can skip watering altogether. If you bring cacti indoors for winter, they need a little more water in a hot, dry and sunny room.
Transplanting and Repotting
Have you ever seen a photo of an avocado pit in a glass with roots sprouting from the pit? Like most plants, lots of water encourages roots to grow. The same goes when placing most new plants in the ground or a new container—extra, deep watering helps roots establish. But that’s not true of succulents. They need time to heal before you water. In fact, taking a cutting from a cactus to grow a new plant (propagating) means letting the cutting rest and dry before putting in soil!
If you want a mixed arrangement indoors or out, try to make sure your cactus or succulent receives only the water it needs. In the landscape, you can mound the dirt under the plant slightly so that water drains to nearby plants with higher water needs or have a dedicated drip for the succulent that emits less water. Avoid spray irrigation, especially on succulents. In container arrangements, keep your cactus in a small plastic container half-buried in the container’s soil. This helps the gardener pour more water to flowers around the cactus than directly on it, which helps keep the cactus soil from getting soggy.
Do a Little Research
All cacti are succulents, but not all succulents are in the cactus (Cactaceae) family. In general, succulents are known for their fleshy leaves that hold water. Their leaves usually are small as well – leaving less surface for transpiration, which is the plant equivalent of evaporation.
Just like with trees or flowers, every type of cactus and succulent is a little different. For example, Adenium, commonly called desert rose, is a gorgeous succulent member of the Apocyanaceae family, the same one that includes oleanders. Knowing that helps: First, the only true pest of adenium is an oleander caterpillar. Second, although technically a succulent, when the plant is in full leaf and flower season, it needs a lot of energy (sun and water) and can be treated more like a tropical plant. But adeniums drop their leaves in winter, even in indoor containers. When they go dormant, they need little to no water.
In fact, that’s true of nearly all cacti and succulents – they need more water (and some fertilizer) during their growing/flowering periods and just enough to get by when dormant. Most will flower and grow in spring, fall and cooler parts of summer. High summer heat can make them dormant as a survival tactic.
It’s easy to research cacti and succulents in regional garden books and online, using reputable and regional sources when possible.
Although most cacti and succulents grow more slowly than typical garden or house plants, they can outgrow their pots. In addition, succulents grown in pots and watered from a tap can have problems when minerals from the water build up in the soil. That’s a second reason to repot. You can avoid the mineral build-up by using rainwater for cacti and succulents instead of tap. Be sure your plant is in a container that drains well. That means drilling holes in the bottom of any containers that lack them and filling them with planting medium only (no rock or other filtering materials at the bottom).
Of course, soil, location or zone and other factors affect the health and water needs of cacti and succulent. But most adapt to soil and environmental conditions.
Gardeners can adapt to – and enjoy – caring for succulents. Check out our Pinterest page on cacti and succulents for more information and photos.
Need to ease into saving water in the lawn? Or just ease into gardening? As you think about next spring and ideas for improving both the look and sustainability of your lawn or garden, consider adding easy-care plants that need little to no watering. Here are five ideas:
Rosemary (Rosmarinus officinalis). The woody, herbal rosemary is near the top of my list of favorite xeric plants. The only problem you can have with rosemary is if it receives too much water (or snowpack in winter). Otherwise, try a creeping rosemary near a rock or low garden wall. The stems will grow over the surface and you can trim it in spring just to keep it clean and healthy. I’ve seen bushier varieties shaped into small hedges. And man, what a great-smelling hedge! Finally, be sure to plant a rosemary near your kitchen so you can head out and clip cuttings for cooking use anytime of year (at least in zones 8 through 10). We have rosemary plants that come back each year here in zone 6B. They’re near the house in a rock garden, which helps warm them up. Plant rosemary in full sun and only water occasionally after its first season in the garden. Rosemary plants also reward you with tiny lavender-colored flowers in summer. And although I love the taste of rosemary, deer leave them alone. Bonus!
Barberry (Berberis). Barberry comes in several varieties that do well in plenty of sun (or partial shade) and low water. Berberis x ‘Tara’ Emerald Carousel is a type that grows well in alkaline soils, the kind we have here in New Mexico. Depending on the variety, barberry grows a little wider than high. Some Japanese barberries can grow tall – up to 10 feet – so consider that when selecting a plant. Barberry leaves change color with the season, and I’ve seen lime, orange and deep red varieties; they’re all stunning. Several plants along a wall can form a hedge in front of a house or fence. We like the spiky red foliage for its color and texture in our garden and deer usually avoid the plants. Barberries might need a little more water in the first year or so than some plants listed here. After that, they can handle periods of near drought or drought. All you have to do is prune them once or twice a year to keep the shape or size you like. Be sure to wear gloves!
Yarrow (Achillea). Yarrow is considered an herb, but I grow it for its easy care and stunning colors, which include white, yellow and red varieties. Moonshine yarrow has bright yellow flower clusters that you can cut for arrangements. I also pressed a few this year. This truly is one of the easiest plants to grow. Each spring, you simply cut off the dead flower stalks and clean up the plant. By mid-summer, you’ll have color. I even tried trimming spent flowers off one of our yarrow plants this year to see if that would force a second bloom sooner. But the ones I didn’t trim had more blooms in the second wave of flowers than the one I trimmed. Lesson learned. After the initial spring trimming, just leave yarrow alone. The plant also spreads but not invasively, so consider that when placing it in a design. We dug up one that was too close to another plant and transplanted it near our farm to attract butterflies and bees. It needs a little more water when first planted or transplanted. After that, it can get by with no water in all but the most severe droughts and survives winters down to zone 3.
Four-wing saltbush (Atriplex canescens). Native Americans used many parts of the native four-wing saltbush, including leaves and boiled roots, for food or medicine. It’s also useful to wildlife, grazed by deer and antelope. The name for the bush comes from the four paper-like wings that surround its seeds. There’s no real care needed for saltbush, especially in a natural garden, but you can trim it as desired. When saltbush flowers, it takes on an attractive two-tone effect. The native plant is easy to grow in any soil, and can pop up around roadways in New Mexico. Ours grows far from the garden along a fence. We don’t know if the former owners planted it or if it came up from seed. If you’re worried about it spreading, just learn to recognize the plant’s needle-like leaves and pull up any small plants in your garden or yard.
Jupiter’s beard (Centrathus ruber ‘Coccineus’). At first glance, Jupiter’s beard (also called red valerian) doesn’t look like much. The flowers rise above thin, pointed, pale-green leaves. So it’s a lot of foliage mixed in with small, coral-pink flowers. But these flowers pack a punch! They’ll bring bees and hummingbirds to your garden all summer. And they grow best in dry, hot conditions. Still, red valerian can survive frost down to zone 3, or about -30 degrees F. All you have to do is give Jupiter’s beard a sunny spot and water regularly the first spring and summer. Then you can pretty much leave it alone. We water once in spring, depending on rain. You can cut back old leaves and stalks in spring to give energy to new growth. The plant reaches about 2 feet high and wide.
Winter has come late this year, and that’s alright with me. But we’re sure to face a hard freeze soon and it’s time to protect some plants.
The first line of defense, of course, is to choose plants that are hardy down to your average low winter temperature. These plants might look dead in winter, but they come back as spring warms the air and ground. We can’t control the weather, however, so when exceptions to your typical low hit or you really want a plant on the border for your temperatures, you can help that prized plant make it through the winter. Here are a few tips:
Planning ahead helps. When placing a new plant in your landscape, be sure to consider its winter hardiness when you plant. Placing it in a warm microclimate, such as against a south-facing wall or fence, can keep the plant a few degrees warmer when temperatures dive on winter nights.
Mulching over bulbs or around the roots of perennials and even trees can help the ground retain heat. I use raked-up leaves and sometimes straw. In addition, I use rock mulch around xeric plants. The rocks absorb and reflect heat.
Sadly, we can’t all afford or find space for an actual greenhouse. You can buy or create mini-greenhouses around a few plants. Ours only need a small boost, so we often use 5-gallon buckets with the bottom cut out. We sometimes top them with wire for deer protection or cloth for extra warmth. Glass adds even more warmth and a cloche, French for “bell,” is a glass jar that can cover individual plants. There are lots of ideas online for constructing mini-greenhouses out of plastic and wood or PVC pipe, but you’ll need to remove anything that airtight as soon as the temperature warms back up following a freeze. Otherwise, condensation forms inside; the water drops refreeze and actually can damage your tender plant.
A sheet or blanket wrapped around an entire plant helps protect it from freeze on the occasional cold night. Again, this is a temporary fix. If you have an entire section of plants that need protection, it’s better to rig a system with hoops or sticks and fabric row cover. If leaving the cloth on the entire winter, be sure to use a landscape fabric that allows sun and water through. I like to open these on warm, sunny days.
Plants need to head into winter in a healthy state. That includes keeping them watered (at a reduced rate) if you haven’t received precipitation recently. Cold, windy air dries plants out and stresses them. There is no need to prune most perennials before winter. It’s best to let them die off naturally, feeding birds with seeds. You’ll trim trees while they’re dormant in winter. When freeze threatens, you can water the mulch around the plant, but avoid hitting the leaves and branches. The water in the mulch helps hold heat in. I’ve also seen suggestions of placing used plastic bottles filled with warm water around the mulch to conduct some heat during a freeze.
Bring plants inside
No greenhouse? How about the house? My largest geranium loves the sun from our bathroom window, and the humidity likely helps as well. We have so many plants to bring inside that some have to live in the garage, where it can get chilly but hasn’t gotten below freezing. If you want to invest some money, you can buy grow lights for plants that need more sun than available in your home or garage space. Spray the plants off and let them dry a bit before carrying them inside. This helps reduce the chance that bugs tag along for the ride.
