I've just cleared out my greenhouse. The tomatoes were still fruiting,
but not ripening well, the aubergines were more or less over and the
chillis have produced more than we'll use in five years. But the main
reason for clearing it all out was the mould.

You may remember that last year I had some nasty mould in my greenhouse.
(I have no idea what it is, but it produced brown furryness over any
dead matter such as old flower petals on the ends of fruit, and quickly
spread to living material.) I left the greenhouse open over the winter
in the hopes that the frost would kill it, and this year I made sure it
was better ventilated over the summer, as recommended by urglers. This
worked well, until the autumn came and I closed the window to stop the
tomatoes and aubergines (which were only just getting going) from being
discouraged by cooler temperatures. The mould came straight back and
quickly got as bad or worse than last year.

Now that I've got all the plants out (and I don't intend to put more in
there till the spring), and given that on current performance I don't
expect this winter to be as cold as last, is there anything I can do to
help ensure that the mould spores don't survive?

I'd be interested to hear other contributors comments on this suggestion. I
don't know if it is effective.

You could try a sulphur candle. This is a tin of a sulphur containing mix.

You close the greenhouse windows and seal any gaps as well as you can. Light
the candle and get out fast shutting the door behind you. You leave the
house shut up for a couple of days before ventilating it.

The sulphur dioxide produced will kill anything in the greenhouse. It is
supposed to kill off all fungal spores that are on exposed surfaces.

If I told you about Jeyes fluid and Armillatox I might have to kill
you, so I won't.

I would wash everything down with Jeyes fluid. I have an idea that you are
not supposed to use it for this purpose any more, but you can still buy it
and I have used it for years without trouble.

You can't be 100% sure. As soon as you open the door more will come in and
the greenhouse isn't hermetically sealed anyway, is it?

I agree, Botrytis (the fluffy mould in question) is a big problem at this
time of year, I use one of those office type fans in one of mine to keep the
air moving, cut back and remove any foliage that's past its best and
generally try and stay cleaner and tidier than normal, but I do not use any
chemical to clean it all, I can't its got too many plants in it!
