False Aralia

Medium to 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). Grows fuller and faster with more light. Avoid direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute), which causes brown leaf edges. Too little light makes the plant sparse.

Prefers 50% relative humidity or above. Dry indoor air in winter is a common trigger for leaf drop. misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective), a humidifier, or a pebble tray all help. Use a hygrometer rather than guessing.

Well-draining potting mix. Fast drainage is essential. Adding perlite to standard potting soil improves drainage. A drainage layer at the pot bottom helps prevent waterlogging.

Leaf drop is the most common complaint, usually triggered by relocation, temperature change, drafts, or low humidity. Spider mites, aphids, and mealybugs are the main pest threats - treat quickly with insecticidal soap. Root rot follows from overly wet soil.
