A Gardeners Forum Forums General Discussion The Plants and Flowers Forum 30 year old Nandina is overgrown

Hi,

I have Nandinas planted on both side property lines. They're about 30 years old. I've been trying to thin them out manually with loppers, but it's a huge project! Does anyone know what kind of root system they have, as in deep, or shallow? I was thinking of yanking most of them out with a chain tied to my riding lawnmower. Some of them are way over 6 feet tall, & just out of control. Would it be better to use Roundup, etc? I like them, but I've got to get a handle on them. Any ideas would be greatly appreciated.

Thanks in advance,

Jan

Sorry to tell you that you can't get rid of it. It has a runner root system, it's a type of bamboo and just comes right back. Cut it back, thin it out and make it look better but keep in mind it will return. I'm speaking from experience.
