My front yard slopes down to the street (we don't have a sidewalk). At the bottom of that hill is a long row of ditch lilies, bordering the curb, that has been there forever (much longer than 20 years), maybe a yard deep. The daylilies are slowly creeping up the hill, though, and I'd like to restrain them. I don't want to remove them, as they work very well for erosion control there.
Do you think a 5" landscape edging would help? Or would it be pointless? I'm sure some lilies would come up under the edging, but if it would restrain them a bit, it could be worth it.
I have considered bamboo barricade, but that is supposed to be dug in at least 24" deep, and I think that is overkill.
Or do you have other suggestions?
(I thought I posted this question yesterday, but I don't see it today; if I did already post it I am sorry for the duplication.)
