My poly tunnel has developed a problem. With the cold snap the polythene tightened and is beginning to split at one of the support bars. Trying to fit a patch inside to hold the thing together with polythene sheet and sticky tape. Cannot do the outside as it is wet and also hard to reach. I do have a new cover but it will take more hands to get it over and held with sheet clips from a market stall. It is after all about 20 years old but I had hoped it would see me out. If it lasts the winter I can fix it next year has been my motto for too long I think.
