Flowering maple flourishes when given the same conditions as its native tropical habitat. Bright light and warmth will make it thrive in your home -- and flower most of the year.
Height: Up to 10 ft (3 m) if not pruned back. Prune regularly to keep the plant at a maximum of 3 ft (90 cm). Tall plants will need staking.
Light: Bright light to full sun. Shade from the direct sun. Plants that don't bloom aren't getting enough sun. Put your plant in the brightest window possible.
Water: Water thoroughly, then allow the top inch of soil to dry out between waterings. Use a pot with drainage holes, then empty drainage tray to prevent soggy soil which can lead to root rot. If this plant gets too dry, it will quickly wilt.
Humidity: Moderate, around 40-50% relative humidity. Indoor humidity can drop drastically during the winter months. It's a good idea to use a humidity monitor near your plant rather than guess.
Soil: Use a peat moss-based potting mix.
Fertilizer: Feed every 2 weeks spring through fall with a high-phosphorus water-soluble fertilizer diluted by half.
