And, the second problem is, will the virus, or whatever it was, stay
in the
soil and affect next years plants?

I'm going to take the plants down to the tip rather than put them on
the
compost heap.

Hi Alan,

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??

Regards

Drew

The Victorians used to use something that looked like a brick barbeque
and baked the soild but for the life of me I can't remember the temperature.
