Prep Now for a Great Edible Winter Garden

Growing winter veggies is a fun and valuable effort more people should experiment with in our area. In many ways, winter gardening is a lot easier than trying to garden in the summer — there are fewer pests, cooler temperatures require less watering and common winter veggie’s seeds are super easy to germinate and then cultivate. Two things are important to ensure success: the timing of starting seeds and modifying the climate to extend the season.

If you're hoping to enjoy sweet, delicious, and healthy salads and other dishes all winter long, it's important to start your seeds by the middle to late August. Unfortunately, by then, we're usually very tired of the heat and of taking care of the plants in our yards. It’s not a time we often think about starting new seeds. However, it's important to start seeds early so the plants can reach a good size before it gets cold. This is where being able to modify the climate in your garden is important on both sides of the spectrum. When starting seeds at the end of the summer and it's still hot, having some sort of shade fabric to keep things a little bit cooler makes all the difference. Later, when it starts to get cool, being able to cover your garden bed with a row cover material, sometimes called Reemay (white polyester nonwoven fabric), modifies the climate in the other direction by making it a few degrees warmer and more protected — crucial for having productive beds of kale, Swiss chard, beets, lettuce, spinach, radishes and other yummy veggies. Most of those veggies are super easy to germinate, usually popping up within a couple of days — another reason why this kind of gardening is especially fun for beginners or people feeling frustrated with starting seeds.

Winter Gardening with Hoops

Being able to walk out to your garden and harvest a colander full of fresh kale and Swiss chard is a true delight and can save a lot of money if it's something that you purchase at the store regularly. Winter gardening is easier because the temperatures are cooler and you have to water only once about every two or three weeks, December-February. Also, the cold temperatures don't allow for many pests. Some of my favorite veggies to grow in the winter are kale — I really enjoy red Russian and Dino — beets and collard greens, all of which increase in sweetness substantially once the temperatures begin to drop.

There are substantially less pests in the fall, winter, and early spring compared to the summer. Two pests that you might encounter are aphids and cabbage worms which are relatively easy to manage. Cabbage worms can be avoided by covering your plants with the row cover material to exclude the cabbage moth from laying eggs on your tender greens.

Another advantage of having hoops and shade or frost fabric is that it can protect plants from hail damage. Similarly, some people like to start their tomatoes under row covers to exclude leaf hoppers which can transfer the curly top tomato virus (Learn More in this article by NMSU.)

Creating hoops for your garden to help modify the climate and extend the season is easy to do using common materials — ½” by 10-foot lengths of PVC, 2-foot lengths of 3/8” rebar (both items can be purchased pre-cut at home improvement centers), extra-large binder clips (available at office supply stores), row cover material or shade fabric (available at some local nurseries and greenhouse supply stores), and some stones or bricks to help hold down the fabric at the edges and ends. You may also consider having loose-weave burlap to lay on the soil to facilitate seed germination and keep foraging birds at bay.

Other Tips:

  • Use burlap to help retain soil moisture between waterings and keep birds away when germinating seeds.
  •  A thick, 3-4” layer of mulch such as straw or leaves (once seeds have germinated) is incredibly helpful for keeping moisture in the soil and regulating soil temperature.
  • If you have room, allow winter veggies such as arugula to flower and go to seed. Arugula flowers are beautiful and beneficial for pollinators. If left to go to seed, they also benefit birds and often result in new “volunteer” plants the following year.
  • You don’t need much space for a winter garden — a thriving 4’ x 8’ bed of leafy greens is plenty for a small family.
  • Installing hoops is simple: Pound the 3/8” rebar about 12”-14” deep, slip the ½” PVC over the rebar, clip the fabric to the PVC with extra-large binder clips and weigh down the edges and ends with stones.
  • A 10’ length of PVC on a 4’ wide bed makes a hoop about 4’ tall. Having a 12’ wide piece of row cover fabric allows for 1’ on each side to secure it with stones.

Alkali sacaton, Sporobolus airoides

Alkali sacaton, Sporobolus airoides

Type: Deciduous

Exposure: Full Sun

Water Use: Low

Mature Size: 2’ x 2’

Alkali sacaton is an extremely drought tolerant warm season grass that adapts to most soils in our area, growing in sun or shade. It grows up to 2’ high and wide in tough clumps, putting out grey green leaves followed by graceful airy gold seedheads beginning in June. It’s perfect combined with bold plant forms as they contrast with its fine textured seed heads that create a soft glow at sunset. It’s a great grass to use for erosion control on large sites or to plant in a large group for a beautiful low water use grass meadow.  Trim this grass down to about 4” of the ground in late winter.

Why We Hate to Love the Bermuda Lawn

Why We Hate to Love the Bermuda Lawn

If you have heard of Bermuda grass or live in one of the older areas of Albuquerque, just the name might make you flinch or grimace. The reason it gets a bad rap is because it is dormant in winter, it spreads like crazy into garden beds and can magically appear out of a dirt mess after monsoon season.

You may be surprised to hear that some of us actually like Bermuda grass lawns. In fact, I’ve even planted the grass in my backyard. I’ll take you through the pros and cons and why I’ve come to love the Bermuda grass lawn. It can be the right plant for the right space to fill the right need.

Many homeowners would like turfgrass but feel irresponsible watering a lawn in the arid Southwest. The key to choosing a turfgrass is to determine the one most suited to the specific needs of your landscape The Water Authority is not anti-lawn that is efficiently irrigated and physically used and enjoyed. Bermuda grass cultivars are one means of having a traffic/play/dog tolerant surface that uses half the amount of water of a traditional cool season lawn

According to the “turf research lab” at New Mexico State University (NMSU), “Certain turf characteristics, such as climate adaptation, water use, traffic tolerance, color, quality, maintenance requirements, and available resources, are all factors that need to be considered when selecting a turf species. Climatic adaptation and traffic tolerance, which largely determine the future use of the turf area, are the two most important factors. Many problems encountered in maintaining turfs can be attributed directly to selecting the wrong turfgrasses for Albuquerque’s difficult growing conditions and to the lack of resources, especially water, that homeowners and professional turf growers face in the state.” This means that understanding how much traffic (kids and dogs playing) and our very dry local climate are how we should be selecting turf grass species not what the big box store happens to have in stock.

There are two different categories of turfgrasses: cool season and warm season. Common Cool season grasses are Kentucky Bluegrass, Perennial Ryegrass and Tall Fescue. These are cold tolerant, green most of the year and hold up to extensive foot traffic. But they use a lot of water, up to 50” a year If efficiently irrigated. The water authority frequently has many customers (especially commercial customers) that water grass 80-100” per year! in a town that only gets an average 8” of precipitation. Common warm season grasses are Bermuda grass, Blue Grama and Buffalo Grass. Warm season grasses have a shorter growing season. This means they green up in mid spring, are low maintenance and require less water than cool season grasses. But blue grama and buffalo grass can’t take extensive foot and paw traffic plus they go dormant in the winter.

In my case, I had an existing native buffalo and blue grama grass lawn. It had always been perfect for our home. It’s native, low water use, easy to maintain and beautiful to look at. Fast forward to three kids and two dogs later. I was noticing wear and tear in certain areas of my lawn from two large dogs leaving run paths and kids playing soccer. I’m a professional landscape architect and knew Bermuda grass is a prolific spreader but in this case, I was actually looking for a grass to take over and fill in around the heavily accessed places in my yard. I found a species that could meet both my needs called Cynodon hybrida Dog Tuff ™ Grass Plugs, originally from High Country Gardens. There are many cultivars available check out the many options researched by NMSU. It is a Bermuda grass hybrid perfect for high traffic and play areas. It has excellent durability in yards with dogs. Once established, it is highly weed resistant, deep rooted and provides a soft, cushioned feel for bare feet.

The grass itself “produces an extensive system of creeping rhizomes and stolons commonly called runner roots that often have a scaly appearance. It also produces fibrous roots at the stem nodes.  Bermuda grass reproduces through seed and vegetatively through rhizomes and stolons,” according to NMSU, allowing it to spread with just a little bit of water, around 20” a year. I find that it rarely needs mowing because of the traffic we give it. I mow it about twice a summer to the highest setting my mower goes around 4”.

The data on this grass comes from NMSU, which has turf study sites in Las Cruces and Farmington. A few key points from their study sites mentions that “Bermudagrass (Cynodon dactylon) is similar to Kentucky bluegrass in its tolerance to traffic and turfgrass recuperative capabilities after stress or damage, but it appeared to be more aggressive than Kentucky bluegrass during hot weather in mid-summer.”  NMSU evaluated five different varieties of bermudagrass, Guymon, Riviera, Wrangler, and Yukon, at both their northern NM and southern NM sites.  “Riviera was given higher quality ratings than the other varieties due to finer leaf blades. Being a warm-season grass, the bermudagrasses required less irrigation to exhibit a quality comparable to the cool-season grasses.”

The shocking reason homeowners don’t like Bermuda grass is that it can become a troublesome weed, especially in southern NM, so it is wise to separate this grass from garden areas with a dry, unirrigated buffer strip, concrete mow strip at least 8”x 8” or other barrier. I like to design a concrete walk, patio or edger around these grass areas.

I’ve Xeriscaped My Yard, Now What?

I’ve Xeriscaped My Yard, Now What?

Your new xeric plants are in, and everything is looking good. What do you need to do to keep it that way? Start by looking at your irrigation controller. It may be programmed to apply water too frequently and/or for too long in order to get the plants started. If you hired a contractor, they may have set the controller to water every day because it’s easier than getting a call about a plant that doesn’t look great.

Many desert-friendly plants and trees evolved to survive on very little precipitation but also to make the most of abundant rainfall when it does happen. They’ll store the water in their roots or grow larger (and produce more seed for dry years) than they would with only adequate water. A xeriscaped yard doesn’t automatically “save” water — it is up to the homeowner to do the actual water saving by adjusting their irrigation controller. My dog would be “happier” if I fed her as much as she wanted, but it’s wasteful (among other things) to do so. Watering your desert-friendly plants too much may cause them to outgrow the space they were designed for, which might mean pruning them more than they need so they don’t grow against the house or over a path or outcompete other plants. Overwatering also creates lush, tender growth that is more attractive to pests and susceptible to frost damage.

A recent study in Arizona found that xeriscaped yards didn’t have reduced water usage because the homeowners applied the same amount of water as they would for a traditional yard with a lawn and non-natives.   

Here are steps you can take to make sure you’re watering correctly for your new landscape and keeping your plants healthy:

  • Reduce the number of emitters if needed: The best way to do this is by cutting off the drip emitter and installing a “goof” plug in the end of the ¼ inch tubing. This is preferable to trying to pull the ¼” coupler out from the larger line, which creates a larger hole that can’t be easily plugged.
  • Check your irrigation controller: You’ll want to keep the soil moist around the newly installed perennials, shrubs and trees for the first week, and that might mean watering every day if it’s above 90 degrees. After the first week, switch to watering every other day. Then on week three, switch to twice a week. Exceptions would be for cacti, which I would soak once when planting and then water once a week for the first month before tapering off to once or twice a month until established. (Perennials / grasses - 8-10 weeks, Shrubs - 1 year, Trees - 1-3 years.)
  • Check that drip emitters are working properly, especially if a plant looks wilted: Drip emitters often get clogged after a repair is made in the larger ½” or ¾” poly tubing. If you’re using “flag”-shaped emitters and one is not flowing, you’ll want to grasp the body of the emitter while you turn the top “flag” shape counterclockwise 90 degrees to allow the top to separate from the rest. You should do this while the zone is running so that you can see if any emitters aren’t working and so that the water pressure can clear the clog. Once you’ve twisted off the top, you should have a strong flowing stream of water coming out. Hold your finger over the water stream, forcing it into the drip outlet, which clears the clog. 

If you’re using “button”-shaped emitters and one is clogged, you’ll need to cut it off and replace it. Don’t try to pull it off the ¼” tubing, just cut it off and plug in a new one so that the barbed insert has fresh (not stretched out) tubing to fit into.

  • Keep up with plant growth: As your desert-friendly plants grow larger, you can move the emitters farther away from the base of the plant and add new ones if needed; larger plants require more water. There are several ways to do this. You can poke a new hole in the nearby larger poly tubing, insert a ¼” coupler, run an additional ¼” line to the plant and add an emitter. However, if the main poly line is more than a couple of feet away, install a ¼” “T” in the spaghetti tubing and go from there. It saves time and means fewer holes in the main poly line. Remember, when installing ¼” couplers into the main poly, always poke the hole in the side, not the top; that way if you step on them by accident, they won’t break off. Also, if your plants are on a slope, the emitter should be on the uphill side, so water flowing downhill will cover more of the root zone. Check that water wells are still in place and holding water around the plant.
  • Inspect your trees: Check the leaves for any insect damage and the underside of leaves for insect infestations. Also make sure the mulch or gravel isn’t covering up any of the tree trunk above the root flare, which traps moisture that can cause decay or rot. Particularly in fruit trees, this can also allow detrimental insects access to the trunk where they could bore into it.
  • Check the soil around the base of your plants: Often during initial watering, the soil will settle into the planting hole and can expose the root ball, which causes it to dry out quickly. If you observe or suspect this, kneel in front of the plants, move the mulch out of the way and scrape the surrounding soil back around the plant to cover up the root ball. Then replace the mulch and reposition the drip emitter as necessary.
  • Learn the common or scientific names of your plants: If you don’t have a list, plant tags or a detailed landscape plan, some newer smart phones have a plant identifier built into the camera app (no need to remember the app store password and download another app).  The closer you can get to the plant — showing leaves, branch shapes and flowers (if any) — the better the app will work. The phone (as we all know) can be wrong, but it will give you a place to start. Alternatively, send an email with photos to askanexpert@abcwua.org and we can help you identify

Once you know the plant names you can look them up in our xeriscape guide to reacquaint yourself with their water needs and mature sizes. Need help remembering the plant names? Often the plants themselves can tell you. Is it a catmint? Rub the leaves and smell the minty aroma. Turpentine bush? Lemony pine smell, for sure. Maybe it’s the shape of the leaves. Fernbush? Examine the leaves closely and see how they resemble an actual fern from a rainier climate.
