You need 20.0 lb of Tall Fescue seed.

  • You need 20.0 lb (9.07 kg) of Tall Fescue seed for 2,000 sq ft.
  • New lawns use the full rate of 10 lb per 1,000 sq ft. Once established, overseeding only needs 5.0 lb per 1,000 sq ft.
  • At the price you entered, seed for this project would cost approximately $80.00.
  • Best time to seed cool-season grasses is late summer to early fall (soil still warm, cooler air reduces stress) or early spring.

Next stepPrepare the seedbed: loosen the top 2-3 inches of soil, remove debris, apply starter fertilizer, then spread seed evenly. Water lightly twice a day until germination, then transition to deeper, less frequent watering.
