Q.Hydrangea Blooms Too Small
My hydrangea plants all have very small flowers when they used to be big. What can I do to get my big blooms back? Or what am I doing wrong? I think it has to do with feeding but am not sure even what to feed. Please advise.

Try a high phosphorus fertilizer or add bone meal to the soil around your shrub and see if this helps. Phosphorus is responsible for flowering in plants and a lack of it in the soil will result in little to no blooming.
