Swansea. West Glamorgan., Wales
hi. i have a wisteria shrub approx 7/8 years old growing on a pergola. every year the foliage grows well but it's hardly flowered in all the years we've had it. every year i patiently wait for may to see what it's going to do but yet again this year we have a poor display of flowers. my husband has said to dig it up and replace it with a different climbing shrub as it makes such a mess when it sheds its leaves, and as i have had no showy flowers, i could have something colourful. the actual root and stem, look like a small tree trunk and it is tightly hugging the pergola so we'd have a hard job moving it. i just need to know what i can do to sort the flowering out. i don't know if i am pruning too much or not enough? thanks.
