How many kg for a 30x40ft lawn?

EDIT: LAWN SIZE IS APPROX 60ftx30ft

That's the approx grassy area size. I was looking at the British Seed Houses site and their calculator said I needed about 42kg! I've killed of most of my couch grass ridden lawn with only a few small grassy areas remaining.

Does 42kg seem OTT for this project?

The usual rate is about 2 ounces a square yard, 200 square yards, so 400 ounces, about 25 pounds. About 11 kilos.

the BSH site calculator is for meters not feet

[Snadger]

35 grammes per square metre for overseeding and double that for seeding from scratch.


PS 35g is about a handfull!

Thanks guys. I got about 4kg to start with and section up the areas and do it bit by bit.
