Caring for Your Trees During a Drought
Water-wise practices to keep young and mature trees healthy during drought.
Top Water-Wise Tips
-
Checklist of recommended practices for tree care during drought.
-
Deep, infrequent watering Water slowly at the dripline to reach 12–18 inches deep. Use soaker hoses or drip emitters.
-
Mulch 2–4 inches Add organic mulch to reduce evaporation; keep a 4–6 inch gap away from the trunk.
-
Water early morning Irrigate before 9 a.m. to cut evaporation; avoid watering during windy periods.
-
Protect new trees Newly planted (0–3 years) need shorter, more frequent sessions while roots establish.
-
Limit pruning Remove only dead or diseased wood; heavy cuts increase stress and water demand.
-
Watch for stress Wilting, leaf scorch, early leaf-drop, and twig dieback are red flags—adjust watering.
Suggested Watering Guide
| Tree Age | Frequency* | How |
|---|---|---|
| Newly planted (0–3 years) | 1–2× per week | Slow soak at dripline; 5–15 gal total per watering (size & soil dependent). |
| Young (3–5 years) | Every 7–14 days | Deep water to 12–18"; expand ring as canopy grows. |
| Mature (5+ years) | Every 3–4 weeks | Long, slow session around outer canopy; use multiple emitters/soaker loops. |
*Adjust for heat waves, species, slope, and soil type. Sandy soils need shorter, more frequent cycles; clay soils need slower application.

Quick FAQ
Where should I place the water?
Near the outer canopy (dripline), where feeder roots live—not at the trunk.
How much mulch and how close?
Apply 2–4 inches; keep a 4–6 inch gap around the trunk to prevent rot and pests.
Can I let my lawn go dormant?
Yes. Prioritize trees during drought; lawns recover faster than trees.
