Sanitising greenhouse soil.
The message 5
from Victoria Clare contains these words:
I had a bad mildew problem in my greenhouse this year :-(
I don't really want to cart all the soil out of the main bed and replace it
though.
Can anyone recommend a fungicidal drench or something that might stop the
problem recurring?
Empty the GH, scrub it out, leave the door and vents wide open to let
frost in.
Janet.
