Care Guide

Cyrtandromoea plants are relatively easy to care for, but they do have a few specific requirements:

• Water: Keep the soil moist but not waterlogged. Water thoroughly when the top inch of soil feels dry to the touch.
• Fertilization: Feed once a month during the growing season with a balanced, liquid fertilizer.
• Soil: Use a well-draining potting mix with plenty of organic matter.
• Sunlight: Cyrtandromoea plants prefer bright, indirect light. Avoid direct sunlight, which can scorch the leaves.
• Hardiness Zones: Cyrtandromoea plants are not frost-tolerant and are best grown in USDA hardiness zones 10-11.
