Timing is half of lawn care. Use this calendar as a general guide, and shift it a few weeks earlier in warm climates or later in cold ones. Not sure which grass you have? See know your grass type.
Spring
Cool-season lawns
- Rake up winter debris and check for thin spots.
- Apply crabgrass pre-emergent in early spring, around when soil reaches about 55°F.
- Start mowing once grass is actively growing. Sharpen the blade first.
- Go light on fertilizer. Fall is the main feeding season.
Warm-season lawns
- Apply pre-emergent in early spring.
- Wait until the lawn fully greens up before fertilizing.
- Begin mowing at the recommended height as growth picks up.
Landscaping
- Clean up beds, cut back dead perennial growth, and refresh mulch.
- Plant annual flowers after your last frost date.
Summer
Cool-season lawns
- Raise the mower to the top of the recommended range to shade roots.
- Water deeply about an inch per week. Some lawns go dormant and brown in drought, then recover when rain returns.
- Skip heavy fertilizing in hot weather.
Warm-season lawns
- This is peak growing season. Mow regularly and follow the one-third rule.
- Fertilize according to your soil test.
- Core aerate in late spring or early summer if soil is compacted.
Landscaping
- Water new plants deeply in the early morning.
- Pull weeds while they’re small.
Fall
Cool-season lawns
- This is the most important season. Fertilize, core aerate, and overseed thin areas in early fall.
- Keep mowing until growth stops.
- Mulch-mow light leaf layers back into the lawn. Rake heavy layers so they don’t smother the grass.
Warm-season lawns
- Stop fertilizing as growth slows ahead of dormancy.
- Keep leaves off the lawn.
Landscaping
- Plant trees and shrubs. Fall is an excellent planting season.
- Plant spring-flowering bulbs before the ground freezes.
- Call 811 before you dig.
Winter
- Stay off frozen or dormant grass as much as possible. Foot traffic can damage it.
- Service the mower: sharpen the blade, change the oil, and clean the deck.
- Get a soil test so you’re ready to fertilize correctly next season.
- Sketch out next year’s landscaping plans. See landscaping basics.
