Q: I recently transplanted 400 zoysia plugs from one area of my lawn to an area where the zoysia had not yet spread. The plugs appear fine but there have been a lot of weeds filling in between the plugs. What can I do?

A: I like your idea of using plugs from your existing lawn to propagate more grass. But one of the problems with using zoysia plugs is that you have to control weeds by hand while the grassy plugs grow together. If they were planted on a relatively precise grid, you can use glyphosate (Killzall, Roundup, etc) on a foam paintbrush to paint herbicide on the weeds between the plugs without hurting the grass.
