How to Grow a Jacaranda Tree in the UK
What is a Jacaranda Tree?
Jacaranda trees are beautiful trees with masses of vibrant purple-blue flowers. They’re native to South America, but they can be grown in the UK as well. However, they need a warm growing environment and don’t tolerate frost.
Dwarf Jacaranda Trees for UK Gardens
The best type of jacaranda tree for the UK is the dwarf grafted form, ‘Bonsai Blue’. This variety is much more compact and can be grown in a pot. It can be moved outdoors in the summer and brought inside for the winter.
How to Care for a Jacaranda Tree in a Pot
- Watering: Water sparingly, only when the compost is almost dry to the touch.
- Feeding: Feed once every 2-3 weeks with a general liquid fertilizer during the growing season (spring to autumn).
- Repotting: Pot on into the next size up of container annually in late winter or early spring.
- Pruning: Trim as needed to maintain a balanced shape in early spring.
Planting and Care Guide
- Planting: Plant in a well-drained, peat-free compost in a pot two to three sizes larger than the one it came in.
- Location: Grow in a conservatory or heated greenhouse over winter. Move outdoors to a sheltered spot in full sun from late spring to early autumn.
- Temperature: Maintain a minimum temperature of 5DEGC over winter.
How to Propagate a Jacaranda Tree from Cuttings
Jacaranda ‘Bonsai Blue’ is produced by professional grafting and cannot be propagated at home.
Jacaranda Tree Pests and Diseases
- Red spider mite: Improve humidity levels by placing the pot on a pebble and water-filled saucer.
- Whitefly: Use biological controls, such as predatory insects, to manage infestations.
