privacy fence with cannas
Yesterday my next door neighbor wanted me to come over to his house as he had something to show me(a very sweet older man).We went into his backyard and I was so surprised as my cannas were growing under the privacy fence into his yard.He told me I could dig them up and if I could think of something that would stop them from growing into his yard.I talked to DH and asked him if we could put concrete along the two fence panels so they would not grow under the fence.He said NO! Which I wasn't surprised by as getting him to help me sometimes is like pulling teeth.
Does anyone know what I can put along my fence to keep my bulbs from going under it and growing in my neighbors yard?
Thanks to all the help in advance.
