Planting Instructions

Plant Blue Oat Grass in spring or early fall for best results. Dig a hole twice as wide as the root ball and at the same depth. Place the plant at the same level it was growing in the container, backfill with soil, and water thoroughly. Space plants 2-3 feet apart to allow for mature growth. Apply a light layer of mulch around the base, keeping it away from the crown to prevent rot.

For container planting, choose a pot with adequate drainage holes and use well-draining potting soil. The container should be at least 12 inches deep to accommodate the root system. Position the container in a full sun location for optimal growth and color development.
