Seasonal lawn care calendar
Spring (March–May)
- Soil Test & Fertilize: Check pH and nutrient levels; apply a balanced fertilizer heavy in nitrogen.
- Aerate: Relieve soil compaction to allow roots to breathe.
- Overseed: Fill bare patches with grass seed for density.
- Weed Prevention: Apply pre-emergent herbicides to stop crabgrass and other weeds before they sprout.
- Mowing: Begin mowing at 2.5–3 inches, never cutting more than one-third of the blade.
Summer (June–August)
- Water Deeply: About 1 inch per week, early mornings only. In Hayward, stick to drought-conscious schedules.
- Mow Higher: Keep grass at 3 inches to shade soil and conserve moisture.
- Fertilize Lightly: Use slow-release fertilizer to avoid burning during heat.
- Pest & Disease Watch: Inspect regularly for brown patches, grubs, or fungal issues.
- Mulch Clippings: Leave grass clippings to recycle nutrients.
Fall (September–November)
- Aerate Again: Fall aeration strengthens root systems before winter.
- Fertilize Heavily: Apply a nitrogen-rich fertilizer to prepare for dormancy.
- Overseed: Best season for reseeding—cooler temps help germination.
- Leaf Management: Rake or mulch leaves to prevent suffocation.
- Weed Control: Spot-treat weeds before they overwinter.
Winter (December–February)
- Rest the Lawn: Grass is dormant; avoid heavy foot traffic.
- Equipment Prep: Sharpen mower blades, service irrigation systems.
- Plan Ahead: Send soil samples for testing to prepare for spring fertilization.
- Minimal Watering: Only water if there’s an extended dry spell.
