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); east or west-facing windows are ideal. Shading from intense midday sun is necessary to prevent leaf scorch and yellowing. Insufficient light means no blooms.

Moderate to high humidity (60-80%. Group your plants together, set them on a pebble tray with water, or run a humidifier nearby) preferred. Avoid misting (note: misting does not actually raise humidity meaningfully. A pebble tray or humidifier is more effective) directly on the foliage. Instead, set the pot on a tray of moist pebbles to raise humidity around the plant without wetting the leaves.

Well-drained, humus-rich, slightly acidic mix. A good DIY blend: two parts leaf mold, one part coarse sand or perlite, one part peat, one part humus, with a small amount of charcoal for drainage. Good drainage is non-negotiable.

Spider mites, whiteflies, and aphids are the main pest threats. Overwatering and resulting root rot are the most common cause of plant failure. Soggy soil will kill it faster than almost anything else.
