The Tree Chilli can grow to a height of up to 4m (13ft) with a spread of approximately 2m (6ft) although it will be less when grown in a container. The plant is hardy in the very mildest parts if grown in a sunny, sheltered position.
To obtain the best results grow the plant in a container that can be moved to a frost free greenhouse, conservatory or indoors overwinter. During the winter months the plants will loose their foliage due to low light levels. In winter keep the plant on the dry side as a wet compost can cause the roots to rot. The plants can be moved outdoors to a sunny, sheltered position in early summer once the danger of frost has passed. Keep the plants well watered and feed with a liquid tomato fertilizer every 10-14 days when the flowers start to set. The fruits can be harvested when they are still green or allowed to fully ripen.
In very mild areas the plants can be planted outdoors in late May or early June once the danger of frost has passed. Before the first frosts of autumn apply a thick mulch around the root area for frost protection and lightly trim back the plant and wrap it in fleece until the milder weather arrives in April.
