Just as we take shelter when the weather turns colder, so do your plants. This time of year, plants store most of their nutrients in the roots and find shelter in the ground. We can support this transition to help plants thrive during the entire winter season.
Also, it is time to give your irrigation system a rest. The recent storm brought much-needed precipitation and along with the snow came freezing temperatures. To avoid damage to your irrigation system we recommend setting it to the OFF position. Your next step will be to wait for a warm day, to deeply water one more time and then take steps to winterize your irrigation system.
Follow this advice to ensure landscape success:
How much should I water this November?
1-2 more times this month
Give individual trees 100 gallons to a depth of 24”
Skip watering if it rains or snows
Water turf to ½ inch, 7-10 minutes
Your outdoor water usage should be 80% less than in the summer season
How can I keep my landscape healthy this winter season?
Turf
Mow your lawn to 2-2.5 inches. Grass left too long over the winter can develop brown patches.
Aerate next time it is warm. Aerating your lawn will give it a chance to breathe before the grass goes completely dormant. This also provides relief of any compaction that has built up during the warmer months.
Rake or blow off the leaves that have fallen on your lawn. Leaves that are left on the lawn could become moldy, which invites disease.
Top dress with compost. Compost acts as a fertilizer, adds moisture retention capacity, and improves overall turf health.
Trees
Apply a thin layer of compost, about ½ inch, to provide nutrients.
Add mulch away from the trunk base, about 2 inches thick. Mulch helps maintain your ground at a constant temperature and helps retain moisture.
Water your trees thoroughly once a month, if needed, to support your plants' winter hardiness. Withholding water will not aid the plant in acclimating itself to winter.
How do I avoid irrigation and other plumbing system damage? To avoid costly repairs, we recommend that homeowners take the following steps:
Find the master shutoff valve. The master shutoff valve turns off the water to the entire house. If you have one, learn its location. This could be critical if a pipe should burst. Need an emergency turn-off? Call 842-WATR and select Option 1.
Insulate pipes and faucets in unheated areas. Wrap exposed water pipes in unheated areas (such as a garage, basement, crawl space, or space beneath your mobile home) with insulation or heat tape. Be sure to follow the manufacturer's instructions carefully.
Seal off access doors, air vents, and cracks. Winter winds whistling through overlooked openings can quickly freeze exposed water pipes. DO NOT plug air vents used by your furnace or water heater.

The balancing act of watering your trees in the fall and winter is important. Established trees should be watered two to three times a month in the fall season and once a month in the winter season. If not watered properly, trees that get too dry during this time can suffer stress and drought injury. This often does not show up until the heat of the following summer, which then makes trees more susceptible to pests and disease. Fall is the time to set your trees up for winter success.
Other important factors to consider when watering trees:
Newly planted trees (trees planted within 1-3 years), are more susceptible to damage from dry conditions and should be watered more frequently than established trees. Try watering them to a depth of 24 inches three times a month in the fall and twice a month in the winter.
Evergreen trees lose water through their needles in the dry winter air. They need more stored-up water going into the winter season to make up for that. Cold, dry winds can strip water from evergreens faster than their roots can absorb it, too. That is why it is especially important to provide enough water in the fall and during dry, warm spells in the winter.
Even though they lose their leaves, deciduous trees should also not get too dry in the fall and winter. Water acts as an insulator for both the tree and soil. Soil that stays moist will be warmer. Likewise, plant cells that are plump with water will be less susceptible to damage from the cold. Water deciduous trees to a depth of 24 inches twice a month during the fall and once a month in the winter.
When watering any tree, remember to apply water out to the edge of the tree’s canopy drip line. Most established trees have a root spread equal to their height and beyond. Water deeply and avoid spraying foliage. Watering to the right depth depends on your specific soils, so you will want to measure how much water it takes your soils to reach 24 inches deep. Read this article for tips on measuring watering depth.
One of the best things you can do for your trees in the coming months is to add mulch. Layering three to four inches of organic mulch protects the soil from moisture loss and helps regulate soil temperature throughout the winter. Treebates for bulk organic mulch is available.
Pro Tip: "Watering to the right depth and managing the frequency of watering are both very important aspects of keeping our plants healthy throughout the year, but especially in the fall and winter months,” says Patrick Chavez, Trees of Corrales Wholesale Nursery.

Your irrigation system is only as good as its aim. Adjust sprinklers and emitters to make sure they are delivering water to the landscape and not onto rocks, bare earth or pavement.
June is a great time to check and replace any clogged spray nozzles or drip emitters. Remember, each spray head also has its own filter insert that needs checked as well.
Watering Recommendations: Summer is here and so are hotter temperatures! Follow the Water by the Seasons Summer watering recommendations to keep your yard looking healthy. For turf, water 2-3 times per week. Start watering your trees and shrubs 1 time per week to keep them looking good.
Remember, if it rains more than a half inch you can skip your next scheduled watering as there is no need for supplemental irrigation.
As the landscape irrigation season gets under way, inspect your irrigation system for leaks and clogged, broken or missing sprinkler heads and emitters.
Use a pressure gauge to verify that sprinkler heads are operating at recommended pressures, and check and clean all system filters.
Time to follow our Spring Watering Recommendations.

It’s officially winter and cold weather will be here for a while. January’s service tip is to take a moment to inspect the trees on your property to see how they are doing.
Walk outside and take a good look at
your tree, starting with where the tree enters the ground. Your looking to see that
the tree trunk flare out as it goes into the ground. This is called a root
collar.
If your tree goes straight into the
ground, it’s most likely planted too deep. You’ll want to remove the dirt
around the tree until you can see the flare of the root collar.
Next, look up into your tree and check for a main central leader on your tree. Now notice the spacing between the branches. Each branch should have its own space. If your tree looks like it doesn’t have the above characteristics, then it’s probably time to call in an arborist for advice.
WATERING RECOMMENDATIONS:
This winter continues to bring much needed precipitation to meet the needs of your landscape, no need to water this month.
