I wondered about some cheap lawn grass seed.
I suppose you want a fast growing annual thay gets dug in before it
has chance to drop any seed.

You don't want grass seed as such, you want something that fixes nitrogen,
like Phacelia, red clover, or mustard.

Phacelia is especially pretty, we saw a field of it in France some years
ago, didn't know what it was at the time.

Grass stores nitrogen though it doesn't fix it I agree. Clover might
be difficult to get rid of and would it growmuch if planted at this
time of year I wonder.
