Colocasia, is a tropical plant that can be grown outdoors in the UK in the summer months. Here are some care instructions to help your plant thrive:
-
Location: Choose a spot in your garden that gets partial shade to full sun. Colocasia prefers moist, well-draining soil and high humidity, so consider planting it in a boggy or waterlogged area.
-
Watering: Keep the soil consistently moist, but not waterlogged. Water deeply once or twice a week, depending on the weather and soil conditions. If the plant starts to wilt, it may need more frequent watering.
-
Fertilizer: Apply a balanced fertilizer every two weeks during the growing season (spring through summer) to encourage healthy growth.
-
Pruning: Remove any damaged or dead leaves as soon as possible. Colocasia metallica can also be pruned to control its size and shape.
-
Overwintering: In the UK, Colocasia is not hardy and will not survive the winter outdoors. Before the first frost, dig up the plant and store the rhizomes in a cool, dry place until spring.
