My greenhouse tomatoes, the same as a lot of other gardeners, suffered from botrytis last season and I'd like to know if cold weather/frost would kill off the disease if I left the door of the house open.

Personally I think it unlikely as the spoors are in the soil. Have you had the greenhouse open to the elements right through the winter? A serious clean and using fresh soil/compost is really needed.

Do you use a parafin heater? These chuck out the moisture, change to electric fan heater if possible. Ventilate on mild days.

« :) Do you know name of this clematis. I have to prune , but is it 2. or 3 grup?
I wouldn't trust it myself Merlin. I would buy some Jeyes fluid and wash everything down with it, windows, tubs and pots etc. everything! Change the soil/compost that you used. What I mean is if you used growbags last year then get rid of them (not in the compost heap but in the bin).
