I asked a similar question a few months ago, i.e. How do you
sterilize the soil in a greenhouse?

I know that it should be replaced every three years, but is there
a
foolproof method of sterilizing it??

I believe it can be sterilised in a microwave, but it could take a
long time if you have a lot of it.

Didn't they use to recommend dilute Jeyes Fluid? It always puzzled
me, as I couldn't see how it could avoid killing off the beneficial
organisms along with the harmful ones.

I did a brief Ggl on "sterilising soil", which should give you some
ideas. One site was about using a steam wallpaper stripper (bewa
it's a bloody pdf):
