Why are my hydrangea blooms so small?

Question

I planted hydrangea bushes several years ago. The first couple of years the blooms were huge and beautiful. Lately the blooms seem to be getting smaller and more pale each year. What is causing this and how do I correct the problem?

Answer 1

It may be a lack of nutrients, particularly phosphorous. I would give the plant some fertilizer with an extra boost of phosphorous. Bone meal is one way to add phosphorous.
