Aside from a sod cutter, what type of poison couls I ise to remove zoysia grass? Have had zoysia since planting plugs approximately 40 years ago. We're tired of the dormant look of the grass, always brown. You can always tell where the zoysia begins and ends. We're looking for an alternate option to remove, such as a poison. We are not interested in going thru removing sod piece by piece. Just want to kill the grass, and re-seed. Thanks!
