Seed application rate
Grass seed, cover crop, and broadcast seeding use pounds or grams per unit area. Multiply your planted area by the rate on the label to estimate total seed.
Rates vary by species, germination rate, and whether you are overseeding or establishing new turf. Buy extra for uneven spreading and fill — 10% buffer is common.
Example: 2,000 sq ft lawn at 4 lb per 1,000 sq ft → 8 lb seed. Metric: 100 m² at 50 g/m² → 5 kg.
Common questions
Where do I find the rate?
On the seed bag or packet — often lb per 1,000 sq ft for turf or lb per acre converted to your area.
Does this include waste?
No — add 5–15% if your spreader or hand broadcast is uneven.
