I have a wisteria in my back yard, it has not bloomed the last two years. Any ideas as to why?
I bought my house three years ago, and the wisteria was out of control, It was in the neighbors' trees and the arbor it was on was leaning. I trimmed it back and put a new metal arbor under it. I knew it wouldn't bloom the next year as I have heard that it blooms on old growth. Well It grew quite a bit that first year. I really expected to have blooms this year, but nothing! Do you think it might need feeding and if so do I use a general type plant food?
