Q. I have several wisteria plants that are probably offshoots of a main vine. The main vine blossoms like crazy every year but the offshoot plants don’t blossom, even though they grow and send out lots of stringers and look very healthy. I want to train and control these off shoot plants and want them to blossom. What do I need to do to get them to blossom?

A. Some wisteria don’t bloom until they reach a certain point of maturity. Sometimes, laying off the fertilizer for a year helps, too, as it doesn’t promote so much green growth (versus flowering activity).
