I have a customer who has a zoysia lawn and flower beds near the house. Right now they have 4x4 landscape timber as an edging to keep out the zoysia...it's working, but starting to decay and has termites. The new garden design is for the most part all curved flower beds so lumber is out of the question. Any ideas on an edging that can make decent curves and keep zoysia from going under and over the edge. I'm thinking of either bricks set on end or cobbles on end with 3 inches exposed.
