Pam.
I should think that the main objection to re using old compost is
the build
up of pests etc in the compost.
If you don't have to vast a quantity then you could sterilize it
in
your
microwave, you would be surprised how much you could do doing say
3
lots of
say 2 litres a day ( a Pyrex casserole dish with lid works great)
over 2
weeks.

David, for how long do you typically leave the compost in the
microwave?

I leave it until it is hot and steamy!

Do you dampen it before it goes in, or is the natural moisture in
it
enough?

It depends on whether it starts off damp - it needs to be seed
planting
damp to steam well.

Thanks, Nick. I'll try it out in February or March.
