  Hi, I am wondering what the reasons may by that my hydrangeas have not bloomed for the last two years. They have bloomed profusely in the past, but have only slowly leafed out this year and last. They are a lace leaf variety, by the way. Should I replace them? They look pretty healthy otherwise. Thank you in advance. Celia D

  Answer

  Dear celiadoremus, I'm sorry that I cannot answer your question. Cultivated species are a topic that sits outside of the realm of Go Botany. I have observed the very phenomena you mention, in many different species over the years, and have tried to explain this with different seasons not being conducive to flowering, plants exhausting their energy stores one season and needing to recuperate, and young plants that may not be able to flower consecutive seasons. I would be patient and watch them for another season or two. Best wishes.
