Horses like to eat all the time and require some chew time. Some need extra nutrition above the grain and hay that you feed them. Allowing them to graze while they are in the paddock or corral can provide them with extra sustenance. You can grow grass in a corral but it will require some planning. You will also need another location to place your horses while the grass grows. Provide ample time between grazings to allow the grass to establish.
Select the type of grass seed you want to grow for your horses. Clover and Bermuda grass are excellent choices for corrals. Clover is a hardy, inexpensive grass that will grow in nearly any soil, and horses love the clover flowers.
Loosen the dirt in your corral with a tiller or a garden rake. Loosen 2 to 3 inches of soil.
Spread the seed on top of the soil with a spreader or use a shovel and a wheelbarrow. Sow approximately 16 seeds per square inch.
Cover the seeds with 1/4 inch of soil by raking the area gently or dragging a length of chainlink fence across the area.
Water the seeds with a garden hose or with a sprinkler on fine mist. Apply 2 to 3 inches of water to the area.
Check the length of the grass after 14 days. Turn your horses out in the corral when the grass is 6 to 8 inches tall. This will take approximately 14 days in the spring and fall and up to 30 days in summer.
Divide your pastures into five separate paddocks or corrals. According to Montana State University Extension, you should not allow your horses to graze for more than seven days in one area. Divide the areas up so you can rotate where they graze.
