I have mopheads that growing on both old and new wood is that possible. I had beautiful flowers for the first couple of years but now only the city line hydrangeas are blooming. I have fertilized the plants, covered them over winter, I did not prune them in fear of cutting the buds. They are in full sun and some in part sun. I have no idea why they won't bloom. I have a lot of plants and they were expensive. The plants are about 8 years old.
