Using Buffalo grass as a groundcover
Buffalo grass forms a low mat. It fills in densely, crowding out most weeds. It takes moderate foot traffic, so you can walk on it regularly. It holds strong cover through Front Range winters, so the ground doesn't go bare.
Planting & establishment
Water 1×/week first summer to establish. Goes dormant (tan) in extreme heat; greens back up with rain. Mow at 3 inches or leave unmowed.
