How to Maintain Your Irrigation System in Modesto’s Climate

Keeping your landscape healthy and water-wise in Modesto’s dry climate requires smart, seasonal care. From spring start-up to winter preparation, regular maintenance helps your native and drought-tolerant plants thrive year-round. Here’s a simple seasonal guide to keep your yard looking its best—no matter the weather

🌼 Spring (March–May): Start-Up & Preparation

• Inspect irrigation system
  Check for leaks, clogs, or broken emitters. Adjust drip lines and sprinkler heads for new growth.

• Apply mulch
  Refresh mulch (2–3 inches) to retain moisture before summer heat sets in.

• Prune native plants
  Lightly shape Manzanita, Ceanothus, and sages after blooming to encourage healthy growth.

• Fertilize if needed
  Use organic or slow-release fertilizer on young plants and trees.

☀️ Summer (June–September): Heat & Water Management

• Check irrigation weekly
  Adjust watering times as temperatures rise. Water early morning or evening to reduce evaporation.

• Watch for heat stress
  Look for wilting, sunburn, or dry leaf edges—especially in new plantings.

• Control weeds
  Hand-pull or spot-treat to reduce water competition.

• Protect young trees
  Use tree wraps or mulch basins to keep roots cool and conserve moisture.

🍂 Fall (October–November): Clean-Up & Planting

• Plant natives
  Fall is the best time to plant drought-tolerant natives like California poppy, yarrow, and buckwheat.

• Cut back spent perennials
  Trim down dried grasses and flowers, but leave some seed heads for wildlife if desired.

• Check irrigation again
  Reduce watering frequency as temperatures drop.

❄️ Winter (December–February): Dormant Season & Prep

• Winterize irrigation system
  Shut off and drain if needed. In Modesto, deep freezes are rare but possible.

• Prune deciduous trees
  Do structural pruning while trees are dormant (e.g., Valley Oak, Redbud).

• Remove fallen leaves/debris
  Clear plant beds to prevent mold, pests, and diseases.

• Plan for spring
  Assess plant performance and layout; prep for any changes or additions.
