Does lawn edging really work? invasives, too?
I've always wondered about that lawn edging stuff that goes about 6" into the ground. Does it really keep out grass or anything with a creeping root propogation? I'm wondering if it would work well in the middle of the garden with plant that spreads with stolons, like mint. nhbabs just let me know my Joe Pye Weed will spread by stolons. What if I surrounded it with some kind of garden edging? I just have hard time believe the plant roots just wouldn't go down enough to escape underneath the eding. If it were 12" wouldn't have any worries. But 6", and really often under 6", just seems so shallow.
I'm thinking about using it to separate yard and garden, but my biggest interest is in using it in the flower bed for spreaders that go by root.
