Blue Hydrangea

Question

I have 5 blue hydrangea bushes. One has not bloomed for 3 years and three more have not bloomed this year, leaving me only one that has bloomed. They all have bloomed at least once and they are in different areas of our yard. We live just south of Kansas City, MO. What am I doing wrong?

Answer 1

This could be a factor with pruning or they may simply be in need of some phosphorus. These articles may help: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm
