Propogation time
Spring
Taro produces edible roots in thick tuberous bunches that are ideal for division propagation.
Carefully expose the roots of the plant by digging them into the soil 8 to 12 inches from the base of the plant. Loosen the soil around the plant.
Pull the roots of the plant apart with your hands. Separate the tubers, which look like thin, ribbed potatoes, and separate the roots from the main plant with a sharp knife. Make sure each tuber has at least one bud remaining (a bud is a small sprout on the tuber).
Choose a planting location with well-drained soil in partial shade. Dig one hole 2-3 inches deep for each tuber. Position the holes 2 feet apart and the rows 4 feet apart. Place one tuber in each hole with the bud up. If the bud on the tuber is not clearly visible, plant the tuber horizontally.
Add 1 teaspoon of slow-release high phosphorus fertilizer to each hole and water the area well.
