Taro Overview

Colocasia as a genus is one of three similar genera that originate from Malaysia. Its members can be deciduous or evergreen, tuberous-rooted perennials. It is often found growing along river banks and has a dormant period during the dry season in places like South Africa. Colocasia species have large, round or arrow-shaped leaves, often with conspicuous veins. Insignificant flowering spathes are rarely in cultivation. Colocasias can be used effectively as marginal plantings in ponds and lakes. They grow best out of full sunlight and thrive in wet soil. All parts poisonous if eaten uncooked, and leaves may irritate skin.

Common problems with Taro

This species has a constant battle with hornworms (Hawk moth caterpillar) and cutworms. The best method to control them is to remove them by hand and to keep monitoring them regularly. Other problems that occur with this species is tuber rot if kept wet over winter, and southern blight.

How to harvest Taro

Harvest fruit or seeds after flowering period and sow immediately as the seeds do not store very well.

How to propagate Taro

Seed

Red seeds with a fleshy seed coat emerge after pollination. The seeds are extremely viable and will germinate after two weeks after sowing immediately. Remember to remove the fleshy seed coat before sowing the seeds as the seed coat inhibits germination.

Division

Divide corms or collect offsets during the dormancy period.
