For smaller plants with six to 10 stems, place a soil knife between the separated stems and saw straight down through the thick, fleshy roots that form the crown. Continue cutting all the way through the root ball. For larger, heavier root balls, use two garden forks placed back-to-back to pierce the center of the crown. Push the forks apart until the clumps separate.
