Colocasia ‘Black Coral’ and similar varieties, also known as elephant ears, can be a bit more challenging to grow in the UK due to its climate. These plants are native to tropical and subtropical regions and thrive in warm, humid conditions. The UK’s climate, which is more temperate and can be cooler, especially during the winter months, might require some extra care to successfully grow Colocasia ‘Black Coral’.
Here are a few considerations if you’re looking to grow Colocasia ‘Black Coral’ in the UK:
- Temperature: These plants are sensitive to cold temperatures and frost. They are typically grown as summer ornamentals and should be protected from frost during the colder months. If you’re in a colder region of the UK, you might need to dig up the bulbs and store them indoors during winter or provide them with winter protection.
- Sunlight: Colocasia plants prefer bright, filtered sunlight. In the UK, they might benefit from being placed in a location that receives ample sunlight during the summer months, but not direct midday sun which can be too intense.
- Soil and Water: Colocasia plants like consistently moist soil, but they don’t tolerate waterlogged conditions. Plant them in well-draining soil and ensure they receive regular watering, especially during the growing season.
- Humidity: Colocasia plants prefer high humidity. In the UK’s drier climate, you might need to mist the leaves regularly or place the plant in a location with higher humidity, like a bathroom or near a humidifier.
- Container Growing: If you’re concerned about the cold temperatures, you can consider growing Colocasia ‘Black Coral’ in containers. This allows you to move the plant indoors during colder periods and control its environment more effectively.
- Mulching: Applying a layer of organic mulch around the plant’s base can help retain moisture and provide some insulation during cooler periods.
- Feeding: Provide the plant with a balanced fertilizer during the growing season to support healthy growth and foliage development.
