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), ideally 6-8 hours per day. More light means more vibrant leaf color and compact growth; too little light and the leaves fade toward plain green. An east- or west-facing window is ideal. Direct afternoon sun can scorch leaves.

Prefers high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby), 40-80%. Use a humidifier, pebble tray, or group it with other plants. Dry air causes brown leaf edges and invites spider mites.

Well-draining, rich, slightly acidic soil (standard peat-based potting mix is naturally slightly acidic, pH 5.5-6.5, which is perfect) with a pH of 5.5-6.5. A mix of peat moss or coco coir, perlite, and pine bark works well. Good drainage is non-negotiable to prevent root rot.

Leaf drop is the signature complaint and is usually triggered by cold drafts, dry air, overwatering, underwatering, or simply being moved. Spider mites, mealybugs, and scale insects are the common pests. The milky sap causes skin irritation - wear gloves when pruning.
