Growing Colocasia (Taro, Elephant's Ear)

Latin Name Pronunciation: cole-oh-kay'see-uh  

Wait to plant your Colocasia outdoors until all danger of frost has passed and the soil has warmed to 60°F. Until then, keep your potted rhizome indoors in a warm (above 65°F), bright location. Move it outdoors once evening temperatures remain above 50°F in your area. Acclimate transplants to outdoor conditions slowly to avoid scorching the foliage. Plant in average to damp soil. If rhizomes are actively growing prior to planting, they will also fare well in soggy soil or even shallow water. Fertilize monthly with a balanced fertilizer (10-10-10).

Elephant's Ears are hardy to Zone 8 (10°F). In colder climates, they can be overwintered indoors in their container or dug and stored bareroot. Before the first frost in fall, lift the clump of rhizomes with a spade or fork. Store rhizomes in peat moss to help retain moisture, and keep them in a cool location (50–60°F) for the winter.
