Mature Growth
Throughout growing seasonPlant reaches full size with maximum leaf production; occasional small flowers may appear
Continue regular fertilizing and watering; maintain humidity; remove any damaged leaves; enjoy as ornamental foliage
Dormancy
November-MarchLeaves yellow and die back as temperatures cool below 50-55°F or day length shortens in fall

Harvest Tips
Elephant's Ear is grown for foliage rather than harvest. Pinch off flower spathes to encourage larger leaf production. In fall before first frost, carefully dig tubers, allow to dry for 1-2 weeks, dust with fungicide, and store in cool (50-60°F), dry location in peat moss or sawdust. Alternatively, store potted plants in dormant state indoors
