Hello, I live in Zone 6a and there are amazing Annabelle Hydrangeas all around my neighborhood. They are in full bloom right now, but mine, alas, is sad. Instead of snowball-like blooms, I only have a few small flowers in bloom. I have tried watering generously, I trim off the dead wood in the spring, I have been fertilizing with phosphorus weekly (Miracle Gro Flower Food). This is at least my fourth year with this sad plant, and I am thinking of ripping it out if I can't get some better results.
