How do gardeners control the spread of Hydrangea?

Hi Judy,

It sounds like your hydrangeas are growing on new wood, but you'll need to confirm that. Click below for an article that should help. Wishing you the best.

First, I would be jumping for joy! Many people struggle to grow hydrangeas like that. The only way to fix the problem would be to dig them out, but I would offer to other gardeners in your area. I am on Nextdoor.com which is a great way to connect with others in your area. Who knows, some may offer to come help you dig out!

have you tried "weeding" it out, trim it back to where you want it and plant other flowers but it may be just trimming it back will help

are you sure you're talking about Hydrangeas, which are a shrub? I've never heard of them 'sending up shoots'

It can be trimmed back one third. But, before you do that you need to know what kind it is since some hydrangeas bloom on the old wood and some bloom on new wood. Trim again after it blooms.

I was going to say: You fortunate one with so many Hydrangeas!!...lol....it has to be another kind of plant....Morning Glory perhaps?? Those are vines though
