Sparse Hydrangea Blooms
I live in an area where the winters are very warm and we rarely have frost. My big-leaf hydrangeas bloom, but the blossoms are very sparse. The bushes are large and grow well; and I prune as I'm supposed to. Why do I not have more blooms? They were planted about 5 years ago.

If you have sparse blooms, it is most likely from a lack of sunlight or a lack of fertilizer. Have the soil tested and if the soil shows no deficiencies, consider ways to get the bush a little more light.
