get hydrangeas to blossom
Looking for help to get hydrangeas to blossom. Mature plants approx. 5 yrs. They did blossom the first couple years. Now I get lots of green, one flower, out of 3 plants. They are for my zone in Maine.

You likely have to much Nitrogen in the soil. This will cause lots of lush green and little to not flowering.
Adding Phosphorous with a fertilizer like Bone Meal will help.
