When and how to divide Pennisetum. Divide in spring when the soil is starting to warm up. Lift the clump and cut it into smaller pieces with a sturdy knife.

If the clump is too big, split the grass in half with a spade while in the ground and then lift the two parts. Replant the divided parts and water thoroughly.
