Spiderwort needs a root zone suited to the identified species. Check the plant label and seasonal growth before choosing a division or watering method.
Identify the spiderwort
Spiderwort covers several Tradescantia species and garden hybrids, including plants with different winter needs. Keep the label when buying or dividing. A hardy border clump should not automatically receive the routine used for a tender trailing houseplant.
Choose the growing position
For a garden spiderwort, match light and moisture to the identified selection. Give clumps room to develop without crowding adjacent plants. Soil should retain some moisture but avoid a site that stays stagnant around the crown.
Support the first season
Water a newly planted division when the root ball begins drying. Do not let a small piece dry completely while expecting the resilience of an established clump. Mulch around the plant without burying young shoots.
Divide established growth
If a clump becomes crowded, lift or separate it at a suitable time for the species, keeping roots with each piece. Cut back damaged foliage selectively and remove spent material. Fresh divisions need stable moisture while they begin producing new roots.
