Low-water Use Tips To Meet Restrictions and Good Water Sense

We spend a lot of time talking about xeric plants, and recently posted some tips on low-water use for gardeners. California has implemented emergency regulations to conserve water during their drought, and the ones related to landscaping are the sort of common sense practices that xeric-minded organizations and gardeners have always touted:

  • Avoid runoff when irrigating.
  • Don’t irrigate during or 48 hours after measurable precipitation.

This post goes into more details on the restrictions, which, along with scheduled days or times of watering, are pretty common municipal regulations in drought-stricken areas.

Avoid runoff when irrigating

Runoff obviously can come from too much water. Of course, good planning of landscape, plant selection and irrigation choices upfront can prevent runoff. Correct an existing problem by first checking the area after the system runs. If you normally water while at work, do a manual run so you can test your system on the weekend. If you have runoff, study where flow occurs. If it’s down a slope, consider terracing the lawn area or welling around the tree or shrubs that you’re watering. You can also cut watering time, of course. If you’re worried about one tree or ornamental that needs more water, cut the irrigation system watering time and supplement the tree’s water every once in a while with a hose or bucket. Don’t waste all of that water irrigating concrete or pavement, and possibly weeds, just to keep one plant healthy. For a small lawn or several plants on a drip system, you can decrease watering time and increase frequency if necessary.

This Albuquerque lawn has some bermuda grass, but notice the terrace to avoid runoff. Also, note the exposed drip lines being reset in the xeric garden area on lower right.

The runoff might be from a misdirected, leaky, plugged or defective head or emitter. It’s easy to turn and redirect the head so the water goes where it should. A small leak in the system can waste hundreds of gallons of water. Plugged sprinkler heads are a common cause of pooled or misdirected water. Running a stiff wire, such as a straightened paper clip, through the emitter hole can clear some debris. If the entire head is full or dirt or grass, you can turn off your system, lift and unscrew the head, soak it and use a small wire brush to clean it. Then rinse it and screw it back on.

Avoid watering a wet lawn

This should be a no-brainer, but I already ranted in my previous post about neighbors who left their automatic sprinklers on no matter the weather. My best advice is to set automatic sprinklers to “manual” and water regularly but only as needed based on weather conditions. You can set a reminder on your smartphone or other device to jog your memory if that’s a concern. But it’s sometimes more difficult to remember to override the automatic setting on the sprinkler, especially if you’re not there to do it! Otherwise, pay attention to the weather forecast each evening and override the auto setting when rain is predicted the night before so you don’t have to add the task to your busy morning schedule. You can always water a little in early evening or the next morning if the forecast is off the mark.

Of course, if you’ve switched out some or all of your turf for a xeric landscape, at least you are using less water. It also means less need for an automatic system. Most xeric plants need such infrequent watering that you’re best served by a manual irrigation system or the totally manual system of carrying a water bucket from your rain barrel only to the plants that need a little more water — and only when they need it!

Other water-saving tips

  • Water early in the morning, especially if you live in a hot climate. Your plants take up more water before the stressful heat of the day, and if you’re using spray irrigation, less water evaporates.
  • Use drip irrigation when possible instead of sprays and sprinklers, or at least keep the spray as low as possible. Spraying water can lead to some leaf diseases, and you want most of the water to go into the plant’s roots, not into the air.
  • Well around plants, especially new plants, any plant that needs more water than others, and anything planted on a slope to trap the water.
  • Choose xeric, low-water and native plants.
  • Use mulch as appropriate to help keep plants cool and roots damp.

Of course, it never hurts to call in a professional landscaper or other pro to get some help with your irrigation system or to better plan your lawn and garden for low-water use. For example, avoiding steep slopes in your landscape (with terraces and other strategies) can prevent water runoff, and use of microclimates can increase plant viability while decreasing water needs.

Fall List of Water-saving Activities

The weather is cool and plants are going dormant, but there still is plenty homeowners can do to improve water saving and plant health for spring. It will keep you in the water-wise frame of mind and cut down on spring chores.

First, if you have automatic sprinklers or drip systems, be sure to adjust them for your plant’s new winter watering needs. I used to lose it when I would see my neighbors’ lawn sprinklers running full force on a windy and frosty November morning, partly because I nearly froze getting into my car, but mostly because of the wasted water. Watering plants too heavily in fall weather can soften them and make them more vulnerable to frost damage. And if you continue to water them too much in late winter or too soon in early spring so that they leaf out, they’re more vulnerable to late frost damage.

Another good fall project is to mulch around plants. Some xeric plants do better without mulching, but those that need a little more water can benefit from mulches that help retain the moisture. Mulching now also protects more sensitive plants from potential frost.

mulch in bed

Mulch in this bed helps hold in moisture. Note the manual sprinkler control near the home’s front door. It’s not much more work and avoids watering when unnecessary.

Well or shore up plants. Leaving a shallow depression, or tiny well, around low-water plants helps hold moisture in, especially right after they’re planted. If you have some trees and ornamentals that already are established, you can shore up some of the water by building up a ridge of soil around the plant’s base. This is particularly helpful for plants on grades to help prevent water from running off the plant instead of soaking in.

If you’re really feeling industrious, start planning for spring by planning or setting up a water harvesting system. It might be as simple as diverting roof water into a flower bed against the home’s foundation or so that it runs through a dry-river bed (an assortment of rocks and gravel made to look like a river) that leads to a favorite tree. Or plan a new xeric layout for your yard.

Raindrops Kept Fallin’…

There’s always some irony in gardening. I’m writing about drought-tolerant plants several hundred yards from an area struck by fire no more than five years ago and under severe water use and fire restrictions all spring. We prefer many xeric plants and inherited a huge and well-planned xeric garden when we moved here in April. Most of the plants survived with no care or water, outside a little rain from Mother Nature, while the property sat on the market for a year. So we were ready to look for more drought-tolerant choices for a slightly cooler zone and purchase rain barrels in case the skies ever opened up.

early rain

Early summer rain. See how brown the grass is? What grass, you say?

People who live in rural areas know their weather. One reason is that they tend to pay attention to the skies, the land, the views. Another is that many grow lawns, crops, or feed for livestock. And one of the best reasons is that no television station, web site or app gets rural weather right. Our “local” weather is mixed in with several other communities in our county, some of which are 20 miles north of us or about 1,000 feet higher in elevation. Considering that the temperature can vary about six degrees between our place and a neighbor who lives the equivalent of a block away but a little lower and closer the river, I figure the people in Atlanta or even Albuquerque really don’t get it.

But when various neighbors told us the last freeze would be “around Mother’s Day,” they were spot on: We had a hard freeze the Saturday before, and no other until October. When they said that the rains would start “on the Fourth of July,” they were close again. It started raining July 1 and pretty much kept raining for nearly six weeks. I have not asked about the need to tie weather events to well-known holidays, but if it works…

rain on patio

So then it really rained. Maybe because we were trying to pour a patio.

So, what do you do when your xeric garden gets rain, LOTS of rain? Well, most of the plants adapted just fine. They grew well and plenty of lovely annuals popped up from volunteer seeds. But guess what else happened? We got weeds. Every kind of weed known to man. Everywhere a weed could grow and some places I thought they couldn’t. In all of the gravel walkways, between rocks and pavers, inside cacti (those weeds are smart!). And pretty much all over the entire 4 acres.

These city folk did not yet have a riding mower; we had a lot of moving expenses and no grass worth mowing before July 1. Then the grass was too wet to cut most days. So by the time we got a mower to the back orchard, the weeds were up to my knees. We eventually conquered the mowing, but lost the battle in much of the garden. My thinking is that the yard and weeds had a year’s head start on us, and it will take us a little time to catch up.

weeds take over

Still raining Aug. 10. See the weeds in that front bed and all along the ditch bank in the background?

I also have been meaning to ask a neighbor what sort of event to expect on Thanksgiving. Maybe our first snow, though I think it might hit sooner. I just hope the snow doesn’t last for six weeks.
