i have a wisteria plant , bought 3years ago.it flowers every year . after the first year of flowering i trimmed back all the leader branches to encourage new branches. since then it has made no growth at all.absolutly none. it’s full of leaf and looks very healthy but there is no new growth and the plant hasn’t changed shape since i cut it back after the first season. any ideas why this has happened.
