Clear the field you want to plant the switchgrass in the fall before the spring you want it to grow. Pull all the weeds from the land and remove any large rocks from the soil with the rake.
Pour 5 to 7 lbs. of switchgrass seed into a hand seeder and distribute the seed to the field in late February or early March, when the ground is still cold and unworkable but the snow has melted. The switchgrass needs the cold, wet weather to break dormancy and grow.
Water the switchgrass stand regularly until the grass grows in the spring, if there is a lack of rainfall.
