When to Sow Grass Seed in Lawns?
Planting grass seed requires you to prepare your lawn so it will help seeds germinate. In addition to preparation, sowing seeds at the right time of year will also help the turf grow into a stable lawn.
The best time to sow grass seed is typically late summer to early fall, such as mid-August to mid-September. This allows the grass seed to avoid competition with weeds. The second best time to sow grass seed is late spring, from April to May.
Grass seed typically falls into one of two groups: cool weather and warm weather. Like the name implies, cool-season grasses (Kentucky bluegrass and fescue) survive better in colder climates. Warm-weather types (Bermuda and zoysia) live better in hotter temperatures.
Overseeding established lawns is a process that allows you to sow cool-weather seed over your current turf. You can overseed your lawn with a cool-weather grass type in early fall; this helps you maintain a green lawn throughout the year.
