I've had my wisteria for about 15 years. It normally grows quickly and I prune it each year. For the last few years, it has put out flower buds which have been eaten by snails before they got the chance to develop. This year there are several flower bud spikes - which I'm keeping a close eye on, but the leaf growth is worrying me; all the leaves are extremely pale - almost creamy yellow as if deprived of light. Is my wisteria dying?
