Rattlesnake Plant

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) is ideal. Avoid direct sun (right in the window where sun actually hits the leaves. A strong grow light 4-6 inches away can substitute), which fades and scorches the distinctive markings. A northern or eastern window with 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) is excellent. Too little light causes markings to fade and growth to slow.

Requires high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby), ideally above 50-60%. Brown leaf tips and edges are the first sign humidity is too low. Use a pebble tray, humidifier, or grouping with other plants. Some sources caution against misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective) directly on leaves as it can invite fungal issues.

Well-draining but moisture-retentive mix; a light sandy soil (cactus mix, or regular potting soil mixed 50/50 with coarse sand) or two parts peat moss to one part perlite works well. Slightly acidic to neutral pH. The pot must have a drainage hole.

Brown leaf tips are the most common complaint, caused by low humidity, fluoride in tap water, or fertilizer buildup. Curling leaves signal underwatering or low humidity. Spider mites, mealybugs, and scale are potential pests. Root rot occurs with overwatering.
