Care & Size Guidance

Care & Size Guidance

The Taro plant grows happily if kept as an indoor plant in a bright room, away from sun light. It will thrive in rooms where humidity is high, as the leaves tend to evaporate massive amounts of water.

Keep the plant pot topped up, moist at all times. Feed with a seaweed based fertiliser to provide the plant with the necessary nutrients for its massive leaves.

It can be kept outdoors in summer, in a sheltered spot. It will thrive next to a pond or a heated Koi pond.

All parts of the plant are toxic and sap may irritate the skin on contact.
