Q.Wisteria Hardiness
I live in Columbus, OH and am wondering how hardy wisteria is. Below what temp do I need before covering my blossoms that are already formed? It hasn’t bloomed the last couple years due to the frost.

It should be hardy in Columbus and the blooms should not have a problem with the frost in your area. I think it may not be blooming due to a lack of phosphorus. Add some phosphorus to the soil. This article will help:
