Hydrangea ID & Eradication
Could you please tell me what this variety is? It's an old fashion "over the fence" variety that was given to us about 30 years ago. It's extremely vigourous and has taken over a large section of lawn. I'd like to eliminate it and replace with another less "invasive" variety. It's just about impossible to dig out the roots and wonder how effective a herbicide would be.
I'd be greatful for any advice.
