How Much Grass Seed for 600 Square Feet?

4.8lbs of tall fescue

for a new lawn — see the table for other grasses and overseeding

Grass type	New lawn	Overseeding
Tall fescue	4.8 lb	2.4 lb
Sun & shade mix	3.6 lb	1.8 lb
Perennial ryegrass	5.4 lb	2.7 lb
Kentucky bluegrass	1.8 lb	0.9 lb
Bermuda	0.9 lb	0.5 lb
Zoysia	1.2 lb	0.6 lb

Seeding rates vary a lot by species — dense-seeded tall fescue needs about 8 lb per 1,000 sq ft for a new lawn, while Kentucky bluegrass needs only 3 lb, and Bermuda 1–2 lb. Overseeding an existing lawn takes about half the new-lawn rate.

More seed is not better: overseeded stands compete with themselves and thin out. Match the bag's stated rate when it differs from these typical values.
