My kitchen garden is being foul to dig this year, because it is
badly compacted. It seems that everything that was bare ground
was compacted by the rain nearly as badly as if I had walked on
it. A couple of questions:

Has anyone else encountered this?

What green manure can I sow (late in the year) to reduce this
effect?

I would like something that is dense enough to discourage grass
etc. from growing and setting seed.

Nick Maclaren.
