How to prune xanthosoma atrovirens

Year-round as needed; late autumn for frost-climate cutback. Sever old or damaged petioles cleanly at ground level using sterilised, sharp shears. In frost-prone areas, cut all stems to 2–3 inches above the corm after first frost and mulch the root zone.

As needed throughout the growing season; annually before winter in frost climates. Xanthosoma atrovirens is a tropical aroid requiring only routine dead-leaf removal. Trim away yellowing, aged, or damaged leaves at the petiole base as they appear throughout the growing season. No shaping or structural pruning is needed. In frost-free climates, simply tidy periodically. Protect from frost or cut back to corm level before cold arrives.
