The Q&A Archives: Non-blooming Hydrangea

Question: My hydrangea will not bloom. I have moved it from a sunny location where it would not bloom to a shadier location where again, it has not bloomed.It is supposed to have the blue flowers. The plant is at least three years old.
Please help.

Answer: The two most common reasons for non-blooming are incorrect exposure to sunshine and poor pruning practices. Since you've already moved your plant, it may settle down and bloom for you once it's fully established in its new location. Your blue-flowering big leaf hydrangea produces flowering shoots in the spring on last season's wood. So, to prune for flowering, reduce the old wood by one-half to one-third after bloom. The shrub will develop new flowering wood the following spring. If it doesn't bloom this year, prune as above in late summer or early autumn and it should bloom the following year. Hope you have better luck with your hydrangea this year!
