Watering. Water when the top inch of soil feels dry. Avoid overwatering to prevent root rot. During winter, reduce watering frequency.
Fertilizing. Feed Clusia rosea with a balanced, water-soluble fertilizer every 6 to 8 weeks during the growing season (spring and summer). Reduce feeding in fall and winter when growth slows.
Clusia rosea is a tough and adaptable plant that grows well both indoors and outdoors. It prefers bright, indirect light but can tolerate some shade. It is drought-tolerant and does not require frequent watering. Overwatering can cause root problems, so allow the soil to dry between waterings. Maintenance is generally low, with occasional pruning to shape the plant.
