Hydrangea Tree #408713

Asked June 21, 2017, 10:02 AM EDT

I have had this hydrangea tree for 10 years. I can’t remember the name/variety. It had gotten quite large for the space I had it in, and after watching Bobby and Belinda Jensen prune the heck out of hydrangea, I did that to mine last year. The resulting branches were long and healthy but not strong and caved under their own weight in wind and rain. It did, however yield gorgeous blooms. I did the same thing again this year foolishly hoping for a different result - but the same thing happened again. So, I tied up the branches but the result is not attractive. Please advise as to how I should go about pruning for another year. . . . or any other advice. Mary Lynn Leff from Buffalo.

I would not prune it severely every year. The stems should get thicker as they get older. Instead do maintenance pruning every year.
