The most common problem gardeners have with wisteria is poor flowering. This can be caused by a number of reasons, including: Young plants grown from seedlings can take 20 years to flower, so avoid disappointment by either buying a plant while it is in flower or choosing a named cultivar Check your pruning technique and timing Look for shredded flowers or teeth marks as tell-tale signs of bird, mice or pigeon damage Take care to water in .dry spells between July and September, when flower buds are forming for next year, as drought at this time can result in failure to bloom Be aware that sharp spring frosts can damage developing flowers, causing them to drop before they open, or to develop in a distorted fashion |
