Hi All,
I realise my preceeding reply was a little terse and I apologise for same.
I’m not at all convinced that Green Manure is of any significant value over using FYM/HM/Garden Compost.
I would agree it is certainly better than nothing if you have insufficient quantities of the aforementioned composts to cover everything.
But that said, with a lot, not all, of these Green Manures they need to be dug in to add any benefit otherwise there is a net loss of nutrients from that particular bed.
As we are no-dig followers digging in is not an option/should be avoided as far as possible – I’m thinking here of Potatoes or Parsnips left in the ground over winter. And remember, depending on your rotation, the Potato Bed and Parsnip Bed will not require that digging for another 4 years so it will have completely recovered by then.
I believe the best way is to create as much garden compost as we can each reasonably manage and supplement this with good quality FYM/HM or indeed Seaweed if your lucky enough to live within easy reach of the coast.
Don.
