It helps hold the mesh down and keep it flat, so pests/predators can't easily hook a claw in it. If let's say you're planning to seed grass over it (or if grass/weeds will naturally grow in) then that will hold it down for you.Okay thanks! Our plan is to cover/bury all the apron mesh with soil. I’ve seen some people talk about using stakes as well- is that just personal choice or are they necessary to keep it down?![]()
