I just discovered this delicate, early bloomer in the past few years when friends suggested Love-in-a-Mist (Nigella damascene) seeds from our local iris farm. The foliage looks much like fennel or dill as seedlings sprout, and nigella also is called fennel flower.
Nigella Is Versatile
We grew multicolored love in a mist in our rock garden. Tim threw the seeds out in fall and by mid-spring, we had fine fern-like leaves popping up from between the rocks. Although Nigella does best in damp sandy soil, ours grew out from under rocks that make up the walls of our xeric garden. The rocks likely held moisture longer than a spot in the open might have. The rocks also trapped the tiny seeds so fewer blew away. Plus, nigella can tolerate dry conditions.
But then we tried another approach – we bought a packet of Bridal Veil (Heirloom White Nigella) seeds from Renee’s Garden and sowed them in early summer in a blank spot of our vegetable garden. This soil is far better in quality, and the seeds received consistent drip watering. The flowers were taller and stunningly white, with maroon to black centers. The plants reproduce from seeds, assuming some seedheads are left on plants at the end of the season.
Sow in Fall or Spring
Although most instructions for growing nigella say to sow in spring, you can sow them in fall in areas with mild winters. They need full sun and grow in zones 2 through 10. That worked well for us last year, but this winter has been dry and consistently colder, so I’m anxious to see how many reseeded in our gardens. The bridal veil flowers in our vegetable garden bloomed later in the year, but were planted later. Sowing the seeds a few weeks apart in spring and fall can help ensure constant blooming of nigella in summer.
Use as a Cut Flower
You can cut nigella blooms for flower arrangements, and even better, cut some of the seedheads. If you cut the flowers to enjoy indoors, leave a few blossoms on the plant so they can dry and drop seeds for the next year. If you get too many, thin them out while small. Enjoy the seedheads after flowering by cutting their stems just after flowers fade, and hang them upside down away from direct sun.
Nigella is easy to grow and a great addition to any xeric garden!
When we write about gardening and post on social media, garden writers usually choose bright, pretty pink flowers or robust tomatoes as our subjects. Yet, many plant lovers can enjoy flowers and also get a kick out of growing edgier plants.
I live with one such plant lover. In fact, he loves spines and poisonous seeds so much that our daughter and son-in-law gave him Amy Stewart’s book Wicked Plants, The Weed That Killed Lincoln’s Mother & Other Botanical Atrocities (Algonquin Books, 2009) for Christmas last year. He likes to read it right before nodding off at night…
I thought I’d share with you some of Stewart’s insights into wicked plants, and list several that thrive in our entryway or rock garden.
Datura and Nightshades
Several deadly plants make up the nightshade, or Solanaceae, family. The one we grow every year (it comes back with a vengeance) is Jimson weed, or Datura stramonium. The entire plant is somewhat poisonous, but the real danger lies in the seeds inside the fruit pod that remains after the flowers fade.
I admit I love the flowers and watching hummingbird moths feed off the blooms, which open at dusk. According to Stewart, Jamestown colonists found out the hard way about the toxic alkaloids in Jimson weed. In fact, the name has evolved from its original moniker of “Jamestown weed.” The Jimson weed is the dry cousin of other toxic nightshades and grows naturally in some of the worst conditions of the desert Southwest.
Castor bean (Ricinus communis) is a member of the Euphorbiaceae family. It’s known for the ricin in the plant’s beans. Eating only a few of the seeds can kill a person. Like the Jimson weed, the toxic beans grow on an otherwise gorgeous plant. In full sun, we’ve had them shoot from seed to 10 feet tall in a summer growing season. The large leaves of the plants we’ve grown turn a dark bronze color. Also like the Jimson weed, the fruit can explode when dried out and scatter the toxic seeds. if you decide to plant this potentially deadly ornamental, you must remain vigilant about cutting off the fruit. I don’t have photos of our castor beans, probably because I keep a distance. But here is a link to more information and some excellent images of the plant and beans.
The spinier and spikier, the better for our sunny hallway. Relatives of the castor bean in the spurge family include the lovely Crown of Thorns (Euphorbia milii). It also has a sticky, white sap called latex that can irritate the skin. I can’t imagine any animal chomping on the thorny branches, but I’ve seen deer eat rose branches, so it’s good to make sure dogs don’t eat the euphorbia. Euphorbias also include poinsettias, which are not truly poisonous, but can cause irritation if the toxins from leaves contact your eyes or stomach problems if children or pets eat the leaves.
Stewart includes larkspur among her “Dreadful Bouquet” flowers. Larkspur is a member of the Delphinium family, and sometimes, the names are interchangeable. Plains larkspur plants are found throughout high plains of New Mexico, Colorado and Wyoming. The plant has dangerous levels of alkaloids in seeds, flowers, sap and leaves and can lead to death in cattle who consume the plains flowers at and after flowering. I love the early spring blooms of larkspur, which reseed between rocks in our garden and took over most of a bed last year. I’ve never seen deer damage, and as long as I wear gloves when handling the plant and avoid taking bites of it, I’m good.
Oleanders are popular shrubs and hedges in warmer Southwest climates (zones 8 through 10). They have long, slender leaves and colorful flowers. Because the plants grow quickly and need little care, they’re popular choices in landscapes. The plant’s sticky sap carries several toxins, including oleandrin, which can cause nausea and vomiting and affect heartbeat. People have been known to commit suicide by eating the plant, but the main concern is to keep curious children away, since it takes eating less to make them seriously ill. It’s too cold here to grow oleander, but we have a beautiful cousin of the plant that has a similar milky sap, a Desert Rose (Adenium), that we keep as a houseplant in winter.
The poppy (Papaveraceae) is a favorite Southwest plant. Many species of poppies have toxins that can hurt animals. After all, Papaver Somniferum is the plant that supplies opium. The opium poppy is illegal to grow, but seldom regulated, says Stewart. That’s largely because of how many plants it would take to supply an individual with enough opium to maintain a habit. Our poppies have spiky leaves that distinguish them from the smoother foliage of an opium poppy.
Other Common but Wicked Plants
Stewart’s book breaks down dangerous plants by plant families and other categories, such as phototoxic plants. These have sap that can burn the skin when exposed to light and include the rinds of limes and other citrus fruits.
One of our favorite summer annuals is Lobelia, which also is called Indian tobacco because some ingredients in the plants cause effects similar to nicotine. In small amounts, lobelia can’t hurt you, but it can be toxic in large doses if used as an herbal remedy. I also love, love, the red bird of paradise, another warm climate ornamental shrub. But Even sweet peas and tulips have toxins in various parts of the plants or bulbs.
The bottom line is this: All gardeners should use caution when choosing plants for their home or garden to make sure curious pets and children are safe (this is an extensive list of both, and toxicity ratings, from California Poison Control). On the other hand, growing a spiny or dangerous plant can appeal to adults and older children, and be a great introduction into plant care and the gardening bug!
As winter drags on, birds need lots of energy and shelter from the elements and predators. The best bird habitats mix shelter, water, natural seeds and nest-building material as spring approaches. Native plants offer many of these benefits, and the more varied a landscape, the more bird-friendly it is. For example, birds in our garden “stage” their visits to feeders or the ground by moving between the thorniest rose bushes and higher trees.
Here are five plants or plant types that make birds safer and happier when temperatures drop without adding a lot to your work, or to summer watering requirements.
Replacing at least some of your turf with native grasses and other native plants helps birds and uses less water. We purposefully leave our native grasses (mostly buffalo and blue grama) long as it dies back in fall to increase shots at reseeding and filling in bare spots. The seeds also provide food for ground-hopping birds, additional food caches for jays to hide the raw peanuts we put out, and dried grass stalks for nests before the grass greens in summer.
Switchgrass, big bluestem and muhly grasses all provide seeds and nesting materials for birds. Karl Foerster feather reed grass (Calamagrostis acutiflora “Karl Foerster”) attracts birds and is a beautiful winter plant, with tall seed stalks that blow in the breeze. There are hundreds of species of the grass, and it grows in zones 5 through 9. Its water requirements are a little higher than some native grasses, but if you plant Karl Foerster grass in a rain garden or low spot, it will get more water naturally and won’t be hurt by the damp soil.
Barberry (Berberus) is a hardy shrub with small thorns along its branches. Depending on the variety you choose, you’ll enjoy deep red or pinkish foliage. The shrubs grow in zones 3 through 8 and retain their leaves in winter in most conditions. Fragrant yellow flowers emerge in spring, and the prickly branches provide good cover for small birds. You can plant several barberries a few feet closer together than recommended to create an attractive, bird-friendly hedge.
Boxwood (Buxus) normally isn’t considered a low-water plant, and I’ve seen countless examples of boxwood to form formal hedges and designs in other areas of the country. It is an easy plant to shape, and makes such a good hedge because its evergreen foliage is so dense. That’s also why birds love boxwood. Although boxwood might look a little formal for a native rock garden, we use ours as a foundation plant near our front door, where we want a more landscaped effect. Since it’s also on the north side of the house, I’m sure birds hide under the bush for cover. The boxwood’s protected, mostly shady location and slow growth habit help the shrub stay healthy with less water than it might need in a sunny spot.
Pyracantha shrubs produce berries in late fall to feed birds as temperatures drop. Also a thorny bush (sometimes called Firethorn), pyracanthas provide safe shelter for birds. What I love about the shrub is the diverse ways you can use it in a Southwest landscape. Leave it to grow naturally (maybe with some shoot trimming after rainy summers) or shape it like a hedge. We had several growing along a distant fence and Tim moved one to the front of the house. The pyracantha transplanted without a blink and just a few scratches. We leave the remaining two out in the yard in their natural state and shape the one in front of the house. I get to see the berries from my kitchen window and saw a Stellar jay eating them this past fall.
Many native shrubs attract birds in winter. Berries, seeds and bushy cover all support wildlife. Ask your local nursery or master gardeners for the best low-water plants in your Southwest zone.
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.
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.
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.
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.
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.
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.
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!
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.
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!
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.
Gardeners in New Mexico, Arizona, Texas and surrounding Southwestern states face unique challenges. And though climate, zone and even drought conditions can vary from one area of each state to the next, we have some common issues:
Even when our regions are not officially in a state of drought, Southwest gardeners know water is a precious resource that we must protect all year.
Weather extremes are pretty common, especially where mountains meet foothills or plains.
Our states’ populations are highly rural. Although we’ve got plenty of large cities, rural gardeners live long distances from the services and products easy to come by in urban settings. So, sometimes we just have to get creative.
Heat is a major concern when growing throughout most of the Southwest.
But help is on the way, and I’m honored to be a part of a team offering a new source for Southwest gardening, along with Ann McCormick of Ft. Worth, Texas; Noelle Johnson of Phoenix; and Jacqueline Soule of Tucson. We want to make Southwest gardening fun and easier for our friends, neighbors and clients.
Join us as we offer information, ideas and sharing specific to gardening in the Southwest on our new blog, Southwest Gardening.
The new year is almost upon us, but gardeners don’t have to wait until spring to dream, plan and even shop for new plants.
You can take some time in winter to plan your garden. Doing so usually cheers my mood and makes me feel like I’m getting something done, even if I can’t do much outside. Here are a few tips for Southwest gardeners for winter planning and shopping.
Check Out New Plant Introductions
Each year, breeders offer new plants adaptable to conditions or resistant to diseases. Many independent testing organizations and growers conduct trials to see how plants fare in harsh conditions such as heat or drought. A favorite regional source is Plant Select in Colorado. The nonprofit organization tests and creates plants for the Rocky Mountains. You can search or browse their plant selections for zone, soil type, sun exposure, water needs and other characteristics. A new 2017 selection is the Sungari redbead cotoneaster (Cotoneaster racemiflorus var. soongoricus). The shrub is a hardy plant and fall stunner in a xeriscape.
All-America Selections also releases trial information on ornamental plants and vegetables each year. Although some of the plants are not suited for New Mexico gardens, AAS includes regional winners for the Mountain/Southwest region. For example, its 2018 winners include Mexican Sunrise Hungarian Pepper F1. This past summer, I sowed 2017 national winner Dianthus Interspecific Supra Pink F1 seeds in a garden bed and the plant bloomed well into fall. You can find AAS winners at retailers that carry national brands such as Bonnie and Burpee plants or seeds (Johnny’s selected Seeds or Territorial Seed Company).
Regional growers and local nurseries often carry new plant introductions. Typically, you can learn about new plants by subscribing to the company’s newsletter or by following them on social media. High Country Gardens (whose chief horticulturalist, David Salman, is from New Mexico) recently released a list of new plants the company offers in 2018.
Finally, the Sunset Western Garden Collection is designed specifically for Western gardeners. Sunset lists a collection of waterwise plants, but you might have to do some research to find out where to buy the plants you spot there.
Order and Review Seed Catalogs
Growing plants from seed takes a little more work, but can save you money. And some plants do better grown directly in the ground (cucumbers and squash come to mind). Even though you’ll have more success and save water by growing plants suited to your region, it’s fun to shop for rare or unusual annuals for containers or other special spots in your garden. It’s much less expensive to buy seeds for plants that probably won’t make it through the winter.
Most seed companies ship catalogs for free to anyone who requests them and I’ve been receiving mine since before the holidays. In addition, you can find online versions of most seed catalogs. Flipping through catalogs can give you great ideas about new or unusual plants or even inspire where to plant them or ideas for companion plants for a particular flower or shrub.
Read and Research
Catalogs are one source of plant ideas, but local and regional gardening books and blogs should be your go-to sources. Combining information on plants featured in your favorite gardening books with catalogs and new introductions can help you begin planning and shopping.
In your research, look for ideas such as drought-tolerant plants for easy care, plants for birds and pollinators, or colors and textures you long to add to your garden. Think about herbs and vegetables your family loves and see if you can grow a variety within your space or time constraints. And always read books and websites with a critical eye for credible information and plants most likely to grow in your zone, soil type, sun exposure or water availability.
If you don’t have a good gardening book specific to your state or zone, find out if your local master gardeners have published a plant or gardening guide. And check out my Resources page for books and links on gardening in New Mexico, xeric gardening and other topics.
Shop Locally and Online
Some gardeners prefer to touch and see plants in person, at least to decide on colors or shapes they like. Just beware that some chain stores offer plants each year that aren’t suited to your region or at least offer fewer plants tested for Southwest and xeric gardens. For example, no retailers in New Mexico offer Plant Select products, but High Country Gardens sells Plant Select through its catalog and online store. Shopping, or at least researching, online also can save time. Many online catalogs have search filters. You might be able to search by plant name, bloom color, bloom time or average temperatures and rainfall.
Many online nurseries let you order now and then ship your plants at the best possible time in spring for your zone. So, there’s really no reason you can’t get a head start. Happy plant shopping!
Jokes circulate on social media this time of year about New Mexico traditions, such as adding green chile to stuffing. And all year long when faced with the difficult choice of red or green chile to top your burrito, eggs and just about anything else, New Mexico diners take the easy but delicious way out, selecting “Christmas” for both red and green, please.
So, we have delicious food, but a few other traditions make the holidays in New Mexico special.
You can hang pretty icicle lights, but a row of luminarias casts a beautiful, flickering light along a path. Made from brown paper bags filled with sand and a small candle, the tradition of lighting luminarias dates back at least 300 years. The meaning of the lights was to welcome the Christ child.
Of course, even something as peaceful as a luminaria is not without controversy. The literal translation of the word is “bonfire,” which is not the intent! Another word for the lights is farolitos, but most agree this stands for the candle placed inside the bag.
Regardless, luminarias are an easy addition to holiday décor. You simply fold down the tops of the bags, fill each with a couple of inches of sand and then place your candle in the middle of the sand. We light them on Christmas Eve. Learn more about luminarias and see some great photos at Visit Albuquerque.
Although not limited to the holidays, red chile ristras are a classic and organic way to celebrate the season in New Mexico. Our dry climate is perfect for chile crops in the warmer, southern portion of the state (like Hatch, of course!). Traditionally, red chile pods are dried in the sun for storage and use later.
Ritras, or a string of red chile pods, are said to bring good luck, and typically hang on a front porch. They’re the perfect color for adding to holiday décor, and you can even find wreaths made with red chile pods.
More About New Mexican Food
Sorry, I have to return to holiday food for a minute. Posole is a favorite holiday meal in New Mexico. Made with hominy, pork, herbs and spices, posole is a hearty soup and meal in itself. We usually flavor ours with red chile. You can cook the pods with the posole or add red chile as you serve.
Queso is a well-known and simple dish for holiday gatherings. Our favorite queso recipe actually comes from neighboring Texas. It’s from Texas Cowboy Cooking by Tom Perini of Perini Ranch Steakhouse in Buffalo Gap, Texas.
And what’s a holiday gathering without tamales? I’ve never tried to make them, because I hear it’s a lot of work. But nothing beats authentic, homemade tamales wrapped in corn husks and steamed to perfection. Then you top them with red, green, or… Christmas!
Top it all off with a few biscochitos and pinon coffee. Here’s my post on the delicious anise-laced cookies from a few years ago.
Winter has come late to New Mexico this year, and that’s OK with me. The problem is even when it’s sunny in winter, we have fewer projects we can do so we feel productive and in touch with the soil and plants. So I thought about a few ideas to lighten my winter doldrums and decided to share them.
One: Take a drive or hike, or some combination.
As soon as fall hit and gardening slowed down, we began to visit spots we seldom get to see during the growing season. We drove up nearby mountains and about an hour away to a walk among stunning petroglyphs. My mood improves from endorphins and simply being outside. And we always see a few native plants we’d like to identify, even if they’re at the end of their growing season.
Two: Grow a winter-blooming indoor plant.
Aside from the pretty holiday mascot, the poinsettia, you can grow a Christmas cactus or amaryllis. I received a beautiful gift of paperwhites (Narcissus) in a clear glass bowl one year. One of these days, I’ll try to force my own. And if you have a warm, sunny window, why not bring in a few of your potted plants? Geraniums can continue flowering in the right conditions, and we brought a shade-loving container with coleus and begonias inside. They might get leggy before the winter’s up, but they make me feel more in touch with summer.
Three. Feed birds and other critters.
Leaving the garden a little messy might seem like a bad idea, and it is tough to watch the demise of your favorite stalks and flowers. But birds continue to feed off the seeds of many plants or seeds spread in fall and early winter winds. Once the seeds fade, birds need a little extra help to get through cold winter nights. We hang suet and a sunflower seed feeder and set out raw peanuts for the jays. I want to keep the birds coming so I have something fun to look at from my window when the sky is gray and the garden mostly brown.
Four. Start a project, like a bee house or raised bed.
Last winter, we replaced the door on our shed, completely revamped a large garden path, created a dry river bed, and took on lots of other fun projects. In fact, we took on so many that we have to come up with some new ones this year. But vegetable gardens might need new or improved fencing or other design and maintenance. Putting in a new paver path or dry river bed are projects that come to mind. You can build a raised bed or make a bee house or butterfly waterer (puddling pool). Or you can repot some of those succulents and other houseplants you tend to neglect in summer.
Five. Make and give garden-related gifts.
Some winter projects turn into gifts for family, friends or co-workers. I don’t have a perfect crafting style, but I know people appreciate gifts from the heart, time and garden. We’ve made lavender sachets, pressed flower arrangements and outdoor lights. You can even pot up some plants in homemade containers.
And on a snowy, cold and dark winter day, spend a little time by the fire drinking an herbal tea and reading a gardening book, magazine or catalog. You can relax, plan and dream!
In the arid Southwest, most plants don’t like an abundance of rainfall. Xeric plants such as lavender or rosemary can be damaged or die from too much moisture in the crown or roots. Sometimes, the location a homeowner places a plant affects watering and alters the plant’s ability to thrive as as it should for the zone in which the gardener lives.
Other times, conditions change. That’s what happened in an area near the foundation of our home when we expanded our back patio. We found that excess water from the patio and rain barrel near the edge redirected water during rains. During monsoon season, a blue mist spirea (Cayopteris) and cotoneaster began to show signs of overwatering.
We needed to divert some water away from the two bushes and recognized the importance of either collecting or directing rainfall. We couldn’t afford a large rain cistern, but we had one natural resource in abundance—rocks. So we built a dry river bed, also called a dry creek bed or dry stream. The project was a way to change up the landscape and divert extra water down to our lawn.
Step 1: Move plants
The first step in our project was to move the plants. We divided the spirea and kept the largest portion to replant; we transplanted two smaller sections on a ditch bank back in our orchard. We ended up removing the cotoneaster, which was beginning to overgrow a path we us regularly and had large areas of rusted, dying foliage.
Step 2: Design hills and valleys; test
We next built up a small hill or berm as a new spot for the blue mist spirea and a new cotoneaster bush. This would allow us to control the plants’ watering better. We dug and scraped a river-like trough to help water drain down and toward the grass. It didn’t take much depth to get water from the patio to the grassy area below. Getting the depth and flow right took some trial and error with a garden hose to simulate the rain and made a few adjustments where water backed up.
Step 3: Add rocks
We already had a pile or two of rocks we’ve dug up. And there is no shortage around here. The first step was to cut and lay down black weed barrier, followed by large rocks along the top and side of the dry river to hold the fabric, direct water and add a decorative, but natural effect. This was followed by addition of medium and smaller rocks. We gathered the small rocks throughout fall and winter, sometimes a few at a time, to fill in.
Step 4: Plant!
All our hard work was rewarded with a new area for planting. We had the two bushes, and moved a small pine leaf penstemon to a lower part of the berm. We purchased several grasses, some perennials and a few annuals to fill in. Then we got lucky and had a volunteer blanket flower crop up in just the right spot. We stopped the rock design a foot or more from the house in most spots and used pecan mulch around those plants. Here’s why: Rocks reflect sun and heat and my office window is right above the dry river bed area.
Pulling out the large cotoneaster and adding rocks has intensified the heat in my office. I know that will ease once the plants grow to maturity. And the heat might be welcome on a cloudy January day. We also lost the first cotoneaster planted. It could have been any of a number of causes, but we likely made a common mistake: not watering enough. I was so concerned with keeping this plant from getting too much water that I failed to account for how much would drain away from its roots and the immaturity of the plant. Our second attempt is going well. It’s also easy to change the flow of water just by placing a rock or two in a certain way. So we check the flow when it rains to look for pooling of water.
Overall, we were pleased with the look and function of the dry river bed. The native grass below it turned green earlier than normal and we stopped problems from mud and overwatering of bushes in the area. This is an easy and inexpensive garden DIY project!
