Spotted Dumb Cane

Tolerates a wide range, from bright indirect light (3-6 feet from a south or west window, or right next to an east window. Under a grow light, 6-10 inches away works well) to heavy shade, though bright filtered light (behind a sheer curtain, or set back 2-3 feet from a sunny window. A grow light 8-10 inches away works well) produces the best growth and leaf color. In winter, some direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute) is fine.

Prefers moderate to high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby). Standard indoor conditions are acceptable but browning tips indicate the air is too dry. misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective) or a pebble tray helps.

Loose, fertile, well-draining medium with good water-holding capacity. Mixes of peat and perlite (1:1) or soil, peat, and perlite (1:1:1) both work well.

Root rot from overwatering is the main threat. Common pests include spider mites, scale, whiteflies, fungus gnats, and aphids. Fungal leaf spot and bacterial blight can occur in overly wet or low-airflow conditions. Fluoride sensitivity causes brown or yellow leaf margins.
