What's the most economical way to buy and grow a green manure and
where do I get it from?


If you have a horticultural shop near you that should be the cheapest.

Failing that, have a look at the url below.

The most UN-economical way is to buy from T&M, Suttons, Marshalls or
Unwins. They all seem to me, far too expensive for anything.

Hope this helps
