I have just taken over a new allotment and have started turning it

Deep beds will allow closer planting but this could give problems
earthing up. I would like to try planting under black plastic. Has
anyone done this? What problems are there?

It's an increasingly popular way of growing them. Your shoots may not
come up in neat rows because they will be searching for light before
you cut the slits to let them through. Slugs can be a problem as you
are creating ideal warm dark and damp conditions for them. One
recommendation is to put plenty of slug pellets down before you lay
the plastic. Another technique I've seen suggested is to plant the
potatoes singly (with a trowel or dibber) somewhat deeper than usual
and grow them on the flat, covering any tubers which turn up on the
surface with a heavy compost or rotted manure mulch. I'm trying that
this year.


Hi Jupiter,

Thanks for the reply. What depth do you plant for the manure mulch
method?

fiffer
I plant mine as normal, though a little closer, in raised beds. As the
shoots grow so I cover with grass cuttings off the lawn. Works for me.
