Grass development


How long does establishment take?

You will need to take special care of your lawn until it is established. Establishment time varies depending upon planting method.

  • Sod — 2 to 3 weeks
  • Sprigs, stolons, plugs — 3 to 6 weeks
  • Seeded lawns — up to 2 months

Grass seeds can take a week or more to germinate.

How do different grasses grow?

Once out of the seedling stage, grasses may grow primarily upward (bunch type) or outward (creeping type).

Cool-season and warm-season grasses

Cool-season and warm-season grasses actively grow at different times of the year. This affects when you should mow, irrigate, and fertilize your lawn.
