Common questions

When should I plant grass seed?

Warm-season grasses like Bermuda in late spring. Cool-season grasses like fescue in early fall.

Is overseeding rate half of new seeding?

Roughly. Overseeding fills thin spots, so it needs about half the seed of a bare lawn.

A thin layer of straw or peat helps keep seed moist and protects it from birds.
