Winter rye grass can improve your winter landscape not only by being attractive but also by improving your garden soil. Winter rye is a cool-season grass that can germinate in low temperatures; in some climates it can stay green all winter long. In the Southern United States, landscapers often over-seed warm-season grasses such as bermuda grass so that, when one goes dormant, the other will thrive. The home gardener can use winter rye grass as a cover crop. It can keep soil from washing away during winter storms and suppress any weeds that may emerge in early spring.

Decide when to plant winter rye grass. For winter use, plant it any time in the early fall, such as September or early October.
Stop watering the plot if preparing to over-seed a warm-season grass. Stop watering about two weeks before over-seeding. The intent is to suppress the warm-season grass so it is easier for the winter rye to take hold.
Purchase the winter rye seeds. Expect to use about 20 pounds of rye grass seed per acre. This seed is often available from garden catalogs or online retailers.
Prepare the area where the winter rye grass will be planted. Clear away any dead or leftover plants if it is in a garden plot. If over-seeding warm-season grass, cut the existing grass as short as possible.
Use a broadcaster to spread seeds over the lawn. Walk the broadcaster back and forth across the lawn, then do it again, perpendicular to the way you did it first. For a small patch you can spread the winter rye grass seeds by hand.
Water the lawn daily until the winter rye grass emerges.
Mow the winter rye grass once a week after it grows more than a few inches high. Set the mower at the 3-inch setting for a lush look.
Fertilize the grass if using it in a lawn. After it is established give it a16-4-8 NPK (nitrogen, phosphorous, potassium) fertilizer.
