How to care for a dumb cane
Loose, fertile, organic soil, indirect light, moderate temperatures and high humidity. Water thoroughly, then let the top inch of soil dry before watering again, which prevents root rot. Keep it out of cold drafts and direct sun. Propagate by division or cuttings. Wear gloves to handle it and wash your hands afterward: the sap irritates skin and can damage eyes. The common name comes from the sap numbing the mouth and throat.
Common problems
Spider mites, scale, whiteflies, fungus gnats and aphids. Fungal leaf spot, root rot and blight are possible.
