Endless Summer Hydrangea: Few Flowers - Knowledgebase Question

Chicago, Il
Question by jhbriick

My endless summer hydrangeas have fewer and fewer flowers each year...a very common problem in the midwest from the internet postings I read. My mom and I are very experienced gardeners and take proper care of them
We are about ready to remove them...any ideas?

Sounds like you've done a lot of research. Endless Summer hydrangeas flower on new growth of the season so the more you prune, the more potential for new growth and new flowers. It may be that yours are getting too much fertilizer. Excessive nitrogen can result in lots of lush, green growth, but sometimes at the expense of flowers. Next spring forego the fertilizer and cut your hydrangea back to promote new growth. I think you'll find that makes a difference. Hope so!
