We just bought a house in Nanaimo with a very old and neglected wisteria vine. It is huge and although it rests on a pergola, it's winding up under the eaves, on the roof, and up against the windows. We have no idea how to prune this vine and would appreciate any tips. Most literature recommends a February pruning and then another pruning in the autumn; is this consistent with this climate? Also, there seem to be mixed views on how much/little to fertilize. Thanks for all help.
