Greenhouse fumigation

[wendyl]

I have emptied my 8' x 4' greenhouse of plants and want to fumigate it before putting in plants for winter protection. I understand old fashioned smoke 'bombs' have been withdrawn and all I can find is a sulphur candle - can anyone recommend this or alternative. I looked up fumigators elsewhere on net and found old (2004) unanswered query . Candle requires ALL plants to be removed and airways blocked this questioner put the point that having removed all plants which might have bugs or disease you would be returning bugs if you then returned them after fumigating. I had some fuchsia with white fly which I have cleaned and treated but they need to go in greenhouse before frost - any suggestions please

a good scrub with jeys fluid will clean out most of the bugs and should kill off any overwintering eggs. As for white fly - if you have already treated the plants then they should be dealt with and they wont over-winter as it is too cold for them.
