My wisteria plants have not bloomed

Question

My wisteria plants have not bloomed in many years. What can I do? We planted these many years ago. They continue to grow very well, but have never bloomed. We did trim the long shoots but it did not help.

Answer 1

This may be because you are either over pruning, over abundance of nitrogen, or fertilizing improperly. A lot if nitrogen in your should may be because of fertilizing improperly, when this happens there are gorgeous leaves, but no flowers. To get rid of some nitrogen in your would add a phosorus based fertilizer.
