we have a grape vine that grows over a pergola outside and also comes into the house to grow over the sun lounge roof. This year the outside part of the vine is as vigorous as ever but not a single leaf has appeared inside, no greenery at all. I never got around to pruning the inside part of the vine last year, just removed the grapes. Would that be why it has failed to grow inside? Also, last year the vine dropped loads of sticky sap all over the sun lounge which it has not done before. We live in south hampshire.
