Amorphophallus atroviridis, commonly known as the Voodoo Lily, is a fascinating tropical plant native to Southeast Asia. While it prefers warm and humid climates, it is possible to grow it outdoors in the UK during the summer months. Here are some care instructions to help you successfully cultivate Amorphophallus atroviridis outdoors in the UK:
-
Planting: Choose a well-draining location in your garden with partial shade or filtered sunlight. Amorphophallus atroviridis prefers rich, organic soil with good moisture retention. If your soil is heavy or clay-like, consider adding compost or well-rotted manure to improve drainage and fertility.
-
Watering: Provide consistent moisture to the plant, keeping the soil evenly moist but not waterlogged. During the active growing season (spring to early autumn), water your Voodoo Lily whenever the top inch of soil feels dry. However, be cautious not to overwater, as it can lead to root rot.
-
Fertilization: Apply a balanced organic fertilizer to the soil in spring and mid-summer to provide nutrients for healthy growth. Follow the instructions on the fertilizer package for application rates. Organic options like compost or slow-release fertilizers are generally preferred.
-
Mulching: Apply a layer of organic mulch around the base of the plant to conserve moisture, suppress weed growth, and regulate soil temperature. Mulching also mimics the natural leaf litter that Amorphophallus atroviridis would receive in its native habitat.
-
Temperature and humidity: Voodoo Lily thrives in warm and humid conditions. In the UK, it's best to grow it outdoors during the warmer months and bring it indoors when the temperatures drop. Protect it from frost and cold drafts. Aim for temperatures between 20-30°C (68-86°F) during the day and around 15-20°C (59-68°F) at night.
-
Pests and diseases: Keep an eye out for common pests such as aphids, slugs, and snails, which may attack the foliage or tubers. Monitor the plant regularly and take appropriate action if pests are detected. Good garden hygiene and proper airflow can help prevent diseases.
-
Dormancy: Amorphophallus atroviridis enters a dormant period during late autumn and winter. As the foliage dies back naturally, reduce watering and allow the soil to dry out between waterings. You can choose to lift the tuber during this time and store it in a cool, dry place, or you can leave it in the ground if you provide sufficient protection from frost and excessive moisture.
