Planting times and rates for grasses that can be established from seed

Not all turf species can be established from seed. Germination of grass seed depends on temperature, moisture, and day-length conditions.

Cool-season grasses

All cool-season grasses can be started from seed. These grasses grow best if seeded in September and October. The next best time to seed cool-season grasses is March - April.

Warm-season grasses

Many warm-season species must be established by a method other than by seed. However, those that can be established by seed are seeded most successfully from mid-April to mid-May.
