Peter I have very green lush hydrangea Bush’s that do not produce blooms. I have added holly tone to soil, two years ago cut them back in august, added the color additive, got two blooms this year. Plants get morning sun . what can I do?
I’d switch from Holly-tone to Flower-tone to get the plant more phosphorus. Also deer can nibble the flower buds off over winter…on older varieties, the buds form on second year growth so, if you cut them back in the fall or deer nibble the buds off, you won’t get flowers the following summer. There two types of hydrangeas that need different pruning techniques. HERE’S A LINK to a great website that can help you figure out which you gave and how to care for it.
