How to Divide Spiderwort

By Home & Garden Last updated Tuesday, May/21/2024

1). Watch for new growth in the spring to divide spiderwort. Thrust the shovel into the soil about 6 inches away from the base of the spiderwort plant. Dig a circle around and under the plant.
2). Lift out the root ball of the spiderwort plant. Lay the plant on the ground.
3). Using your fingers, sharp knife or hand pruners, separate the root ball into three sections. As a perennial plant ages, the center becomes less productive. Discard the center of the root ball clump.
4). Replant the divisions in the same sunlight level, full sun to part shade. Plant the divisions at the same depth as the initial plant. Space multiple plants 12 to 18 inches apart.
5). Water well. Spread 1 to 2 inches of mulch, like shredded bark, around the plant. Mulch helps retain soil moisture. Water two or three times a month the first year if there is no saturating rainfall. After that, rainfall alone should provide sufficient moisture.
