Winter Watering for High Desert Lawns in Southern California

General Rule

If you get one good soaking rain per month in dormancy, no supplemental water needed. Cold alone doesn’t hurt grass.

When to Water

• Soil dry to root depth (probe with screwdriver).
• Before a hard freeze: light watering creates insulating ice crystals.
• Sandy, fast-draining soil may need monthly winter water.

Dormant Grass Still Lives

Roots need minimal moisture to survive. Overwatering in winter causes rot, fungal issues, and waste.
