Small Leaves And Small Flowers

Question

My hydrangea bushes have been beautiful for 4 years with large lush leaves and large blooms. This year the leaves are healthy looking but small with small blooms. Why?

Answer 1

It could be a nutrient problem. Have you fertilized? They don't need a lot. Just once in spring with a balanced, slow release fertilizer is ample. Not enough water also can stunt growth. These articles should help:
