Wisteria Not Blooming
I have a Wisteria that I planted about 2 years ago. It is growing vines like crazy, but won't bloom. I read what to do, such as root pruning and adding phosphate, but my 2 questions are: 1. Is it ok to root prune now? 2. What is a phosphate? I bought some bone meal, which said it had phosphate in it, but I think it also has nitrogen. How would it be labeled in a store? I didn't see anything that just said phosphorus or phosphate. Thank you for your help!

Yes, you can go ahead and try root pruning now. Bone meal is fine for adding more phosphorus to the soil. Here is more information: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/bone-meal-fertilizer.htm
