Recommended rate: 7 lb per 1,000 sq ft for a new lawn.

How do you want to enter your area?

The math:

Seed (lb) = (Area ÷ 1,000) × Rate per 1,000 sq ft

50 lb Bags = Seed (lb) ÷ 50, rounded up

Rate per Acre = Rate per 1,000 sq ft × 43.56

You need approximately

35

lb of tall fescue seed

That’s about

1 bag

(50 lb bags)

For 5,000 sq ft

Rate per 1,000 sq ft / per acre

7 lb per 1,000 sq ft

≈ 304.9 lb/acre (~6.1 bags of 50 lb per acre)

Buy a little extra for edges and touch-ups. Seed keeps if stored cool and dry.
