Mould in greenhouse
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?

Rhiannon 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. Neil Jones http://www.butterflyguy.com/ |

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? Mary Rhiannon |

Mary Rhiannon 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! -- Charlie, gardening in Cornwall. http://www.roselandhouse.co.uk Holders of National Plant Collections of Clematis viticella (cvs) and Lapageria rosea |
