Del Rio Winter Lawn Care and Pump Protection

Winter is the season a Del Rio lawn asks least of you, and the season most likely to be damaged by doing too much. On a well-fed property there is also equipment to think about.

Water far less, or not at all

Cool-season grasses slow dramatically below about 50°F, and warm-season grasses like bermuda go fully dormant and brown. Neither is growing much, and evaporation has collapsed.

Combined with winter rainfall, there are long stretches where a Del Rio lawn needs no supplemental water whatsoever. On a well that is a direct saving in pumping cost, so there is no reason to run the system out of habit.

Check the soil rather than the calendar. If it is damp a couple of inches down, leave it alone.

Overwatering is the real winter risk

Saturated soil in cool weather invites root rot and fungal disease, and where there is any compaction the water simply sits. Standing water, moss appearing, or a persistently spongy feel underfoot are all signs to stop watering entirely for a few weeks.

This is more common than winter drought stress by a wide margin.

Protect the pump and exposed plumbing

Hard freezes are not frequent in the Central Valley, but they happen, and water expanding in a pipe does not care how unusual it was.

Insulate exposed above-ground pipework, the pressure tank connections and any backflow device. Foam sleeves and a wrap are inexpensive next to a split pipe or a cracked backflow assembly.

If the system will sit unused for weeks, drain what you reasonably can from above-ground lines. Standing water in an exposed pipe is what actually fails.

Stay off a frosted lawn

Walking on frozen grass ruptures the blades, and the damage shows as brown footprints that persist for weeks because the lawn is not growing enough to repair itself.

Wait until the frost has lifted before crossing it. On a large property that is worth mentioning to anyone doing winter work in the yard.

Use the season for the work water cannot fix

Dormancy is the right time for pruning deciduous trees and shrubs, clearing beds, repairing hardscape and planning. It is also when irrigation repairs are least disruptive.

If a zone underperformed all summer, or the well struggled to keep up on hot afternoons, winter is when to redesign rather than improvise. Going into March with the problem solved is worth more than any amount of adjustment in July.

Stanislaus County has roughly 20,000 wells, nearly half of them domestic, and county wells tend to be shallow. For anything to do with water quality or testing, Stanislaus County Environmental Resources is the right place to start — this article is about irrigation, not drinking water.

Frequently asked questions

Do I need to water my lawn in winter in Del Rio?

Often not. Cool temperatures, low evaporation and winter rainfall mean supplemental water is frequently unnecessary. Check whether the soil is damp a couple of inches down before running the system.

Can I overwater a lawn in winter?

Yes, and it is the more common problem. Saturated soil in cool weather encourages root rot and fungal disease, particularly where the ground is compacted.

How do I protect a well pump from freezing?

Insulate exposed above-ground pipework, pressure tank connections and any backflow device, and drain what you reasonably can from above-ground lines if the system will sit unused.

Is it bad to walk on frosted grass?

Yes. Walking on frozen blades ruptures them, and because the lawn is barely growing the damage shows as brown footprints that persist for weeks.
