My greenhouse is very old and I haven't used it much for the last few years, for a variety of reasons. Today I thought I would sort it out to get ready for some seed sowing, but it's not in any fit state to use. It's been penetrated by ivy and some of the panes have slipped a little bit, letting in water in several places. I've pulled off the ivy and emptied containers full of water, the next thing would be to clear the benches and floor and give it all a good scrub. Not sure if I dare try the electrics! But is it worth it? Are there companies who would come and renovate a greenhouse? Or should I knock it down and invest in a new one? It's large, about 5m x 3m, and I don't need to grow indoor food crops.
