Q.How Do I Get My 3 Year Old Black Dragon Wisterias To Flower?
I bought them both at 1m high. Planted them on south facing house wall Pruned back whippy strands every July And pruned back further to 2 to 3 buds in January as advised. They have grown and leafed abundantly every year The only thing that I may have done incorrectly was last May/June to also cut back some of the really long strands. But have left them this year. Any advice welcome.
