Propagation Methods
Propagation of Thunbergia exasperata Lindau can be done through different methods such as:
1. Seeds
Seeds are the most common method of propagation for Thunbergia exasperata Lindau. The seeds are collected from matured fruits and sown in a nursery. It is recommended to sow the seeds in a good quality seed-raising mix and cover them lightly with soil. The seeds will germinate within 2-3 weeks, and the seedlings can be transplanted into individual pots after they have developed their second pair of leaves.
2. Cuttings
Propagation of Thunbergia exasperata Lindau can also be done through stem cuttings. Choose healthy stems that are approximately 4-6 inches long and make a clean cut below the node. Remove the leaves from the lower half of the stem and dip it in a rooting hormone powder. Insert the cutting into a well-draining potting mix and water thoroughly. The cuttings should be kept in a warm and humid area to encourage root growth.
3. Layering
Another propagation method is layering. This involves bending a lower branch of the plant down towards the ground and covering it with soil. The branch should be slightly damaged to encourage the growth of roots. After the roots have developed, which can take anywhere from a few weeks to a few months, the branch can be cut from the mother plant and transplanted.
Propagation of Thunbergia exasperata Lindau can be rewarding if done correctly. With proper care and attention, the plant will thrive in any garden.
