I'm researching no-dig methods which recommend never leaving the soil in
my new allotment bare. I've now narrowed the non-dig manures down to
field beans, phacelia and douglasii as appropriate to the rotation.

Question. The peas/beans and brassica beds are going to be mostly bare
(at soil level) for most of the time. Is it a good idea to underplant,
and if so with what?

thanks for any thoughts/experience.
