January is an ideal time here in the Coachella Valley to take a closer look at mulch in your landscape. While often associated with summer water savings, mulch plays an equally important role during our cooler months—especially in our desert climate.
A healthy layer of mulch helps retain soil moisture, reduce evaporation, and moderate soil temperatures. During winter, this insulation protects plant roots from cool nighttime temperatures while still allowing the soil to absorb warmth during the day. Mulch also suppresses weeds, which compete with plants for water and nutrients year-round.
Take time this month to inspect planting basins around trees, shrubs, and garden beds. Replenish mulch where it has thinned or broken down, aiming for a layer about two to three inches deep. Organic mulches such as wood chips or bark break down slowly over time, improving soil structure and helping it retain moisture more effectively.
Mulch also supports more efficient irrigation. With evaporation reduced, plants can make better use of the water they receive, allowing homeowners to water less frequently during winter while still keeping landscapes healthy. Be sure to keep mulch a few inches away from plant trunks and stems to prevent excess moisture buildup.
Refreshing mulch now sets the stage for a healthier landscape heading into spring. It’s a simple, low-cost step that enhances plant health, improves soil conditions, and supports long-term water savings—an easy win for both your garden and our valley’s water resources.
