UK gardener here
I am trying to solve a problem which I had last year as a newbie gardener.
50% of my broad beans were empty!...fertiliser?
I have 250 in at home and my allotment and don't really want the same
problem this year.
I don't want to use man made chemical fertlisers for obvious reasons.
I have googled to distraction and can't find a 'proper' answer cos all of
them want to sell me seeds or a coservatory or something.
Experienced growers in this group is my final search on this, and I would
be greatful for advice.
