Hydrangea stopped blooming
I have a hydrangea that is approximately 8 years old. In the fall of 2013 it was pruned back quite a bit. Before pruning, it bloomed very well every year. For the last 2 years, it has not bloomed at all or maybe just a few blooms. There are a lot of leaves that have a good green color.

Determine the type of Hydrangea you have planted.
Also remember weather stresses can and will play a part in the plants performance. We did suffer and very cold winter across much of the United States.
