The Bengal Trumpet Vine makes an excellent tub plant for the patio or decking. Use a large flower pot or planter (at least 50 cm diameter) with holes in the base. Cover the bottom with a layer of potsherds or gravel. Put some potting compost in the pot and plant the root ball of the Bengal Trumpet Vine at the correct depth. Fill the pot with compost, press firmly and water immediately after planting. Place the pot in a semi-shady area with protection from direct, bright sunlight.

The Bengal Trumpet Vine makes a great climbing plant

The long branches of the Bengal Trumpet Vine can be placed against a trellis or any type of support. Place the climbing support firmly into the pot. It is also possible for the Bengal Trumpet Vine to climb against a wall or fence during the summer.

The Bengal Trumpet Vine is originally from India. Another well-known species is the 'Thunbergia Alata'. This remarkable plant has black specks in the centre and is often called 'Suzanne-with-the-beautiful-eyes'.

The Bengal Trumpet Vine is a free-flowering and fast growing vine and will therefore require water regularly during the summer season and less during the autumn. Feed approximately every 4-5 weeks to ensure more flowers and a more vigorous plant. Deadhead regularly to encourage more flowers.

The Bengal Trumpet Vine must be protected during the winter

This tub plant is not hardy, but it can be preserved easily throughout the winter. Before the first frost, cut back old shoots and place the pot in a cool, light room (10-15˚C). Water moderately, (about once a week) to prevent the soil from drying out. As the weather gets warmer during the spring, you can water the Bengal Trumpet Vine more often and you can place it outside on your patio and look forward to enjoying your Bengal Trumpet once again. Be careful not to leave it out if there are any signs of night frosts.
