Green manure question
New to this forum as I have recently taken over my folks' considerable veggy garden. All going well but wanted to avoid farmyard manure as my two young dogs would just view it as a free buffet!! Seems to be only good things said about green manure, so am after some recommendations for the following areas:
1) Fallow area for 12 months, to be followed by broad/runner beans.
2) Over autumn/winter after beans, to be followed by brassicas.
3) Over autumn/winter after potatoes/sweetcorn, to be followed by onion crops.
Soil is clay dominant, some areas worse than others.
Thanks in advance.
