Keep your lawn green and strong all year. This calendar covers tasks by season. Adjust based on your local climate and grass type. Check soil and weather first.
Spring Lawn Care
Spring wakes up your lawn. Grass starts to grow as days get warmer. Focus on cleanup and prep.
Cleanup and Prep
Rake away dead grass and leaves. This lets air reach the roots. Test your soil pH. Aim for 6.0 to 7.0. Add lime if it’s too low.
- Remove winter debris.
- Fix bare spots with seed or sod.
- Sharpen mower blades for clean cuts.
Feeding and Weed Control
Fertilize when grass greens up. Use a slow-release type. Apply pre-emergent herbicide to stop weeds like crabgrass. Do this when soil hits 55°F.
- Feed cool-season grass in early spring.
- For warm-season grass, wait until late spring.
- Spot treat weeds as they appear.
Mowing and Watering
Start mowing when grass reaches 3 inches. Cut no more than one-third at a time. Water if rain is low. Give 1 inch per week.
For grass types by climate, see our guide to best grass types.
Summer Lawn Care
Summer brings heat. Grass may slow down or go dormant. Keep it hydrated and protected.
Watering Tips
Water deeply but not often. Aim for 1 to 1.5 inches per week. Do it early in the morning. This cuts evaporation. Use a rain gauge to measure.
- Check for dry spots.
- Adjust for hot spells.
- Consider a smart system to save water. Learn more in our smart irrigation guide.
Mowing Practices
Mow higher in summer. Set blades to 3-4 inches for cool-season grass. This shades roots and holds moisture. Mow when dry to avoid clumps.
- Sharpen blades mid-season.
- Leave clippings on the lawn. They add nutrients.
- Avoid mowing in peak heat.
Pest and Disease Control
Watch for grubs and bugs. Treat if you see damage. Apply fungicide for brown patches. Use natural methods where possible.
For common issues, read our lawn diseases guide.
Fall Lawn Care
Fall is prime time for lawn work. Cooler weather helps roots grow strong. Prep for winter now.
Aeration and Dethatching
Aerate to loosen soil. Do this when grass is active. Remove thatch if it’s over half an inch thick.
- Pull plugs every 2-3 years.
- Follow with overseeding.
- See our full aeration guide for steps.
Seeding and Fertilizing
Overseed thin areas. Use the right seed for your zone. Fertilize twice in fall for cool-season grass. Once for warm-season.
- Choose fertilizers for growth. Try options from our best fertilizers list.
- Apply when temps are 50-65°F.
- Rake in seed lightly.
Weed and Leaf Management
Treat broadleaf weeds now. They die easier in fall. Mulch leaves with your mower. This feeds the soil.

Winter Lawn Care
Winter means rest for most lawns. Limit activity. Protect from cold and salt.
Protection Steps
Stay off frozen grass. It breaks easy. Use pet-safe de-icers on paths. Avoid salt near the lawn.
- Clear snow gently if needed.
- Plan spring tasks now.
- Store tools dry.
Minimal Maintenance
No mowing or feeding in winter. Grass sleeps. Water only if dry and not frozen.
