Gardeners
Colocasias thrive in humid conditions. Ample soil moisture is a must. If planting in a container, consider a self watering type with a reservoir. Larger pots will allow room for the underground corm and cormels to grow. When frost threatens, bring plants indoors to overwinter. For best results provide a southern exposure and don’t let soil dry out. Wait for the last frost to
plant outside.
• Hardiness: USDA Zone 7b (5˚ F); frost will trigger dormancy.
• Exposure: Full sun for best color.
• Soil: Rich, moist. Colocasias are wetland plants. Burnt leaf edges can be a sign of under-watering.
• Temperature: The warmer the better for fast growth.
• Fertilizing: Avoid over-feeding.
