It prefers full sun to partial shade and well-draining soil. It can grow in a variety of soil types, including clay, loam, and sandy soil. The best time to plant this species is in the spring after the last frost. It can be propagated from seeds or stem cuttings.
Watering needs
Thunbergia bequaertii De Wild. requires regular watering during the growing season. Water the plant enough to keep the soil consistently moist, but not waterlogged. Reduce watering in the winter months to avoid overwatering.
Fertilization
Fertilize Thunbergia bequaertii De Wild. every two to four weeks during the growing season with a balanced, water-soluble fertilizer. Follow the instructions on the label and do not over-fertilize, as this can harm the plant.
Pruning

Propagation of Thunbergia bequaertii De Wild.
Thunbergia bequaertii De Wild. is a beautiful flowering plant that can be propagated through different ways. The following are the propagation methods:
Seeds
Seeds are the most commonly used propagation method for Thunbergia bequaertii De Wild. To start, you need to collect the seeds from the mature plant. The seeds should be sown in a mixture of potting soil and sand, and should not be buried too deep in the soil. Cover with a thin layer of soil and water gently. Place the pot in a well-lit area and keep the soil moist. The seeds should germinate within two to three weeks.
Cuttings
Thunbergia bequaertii De Wild. can also be propagated through cuttings. Take a healthy stem cutting of about 10-15 cm long and remove the leaves from the bottom part of the stem. Dip the cutting in rooting hormone and plant it in a mixture of potting soil and sand. Keep the soil moist and place the pot in a warm, humid area. The cutting should root within two to three weeks.
Division
Division is the most reliable way to propagate Thunbergia bequaertii De Wild. However, this method should only be done when the plant has outgrown its pot and needs repotting. Carefully remove the plant from the pot and separate the individual stems or clumps. Each stem or clump should have at least one new growth point. Plant each stem or clump in a new pot with fresh potting soil and water it thoroughly. Keep the soil moist and place the pot in a well-lit, warm area.
By following these propagation methods, you can easily propagate Thunbergia bequaertii De Wild. and enjoy its beautiful flowers in your garden or home.
Disease and Pest Management for Thunbergia bequaertii De Wild.
Thunbergia bequaertii De Wild. is a plant species that is typically resistant to diseases and pests.
Common Diseases
However, like any plant, it is still susceptible to certain diseases. One of the most common diseases that can affect Thunbergia bequaertii is leaf spot. This fungal disease causes small brown spots to appear on the leaves, which can quickly spread and lead to large areas of necrosis. Root rot is another potential fungal disease that can occur in plants growing in overly moist soil conditions. Avoiding overhead watering can help to prevent these diseases from developing.
Common Pests
Thunbergia bequaertii is also relatively resistant to pests. However, some pests may still cause problems. Aphids, for example, can damage plant tissue and attract additional pests like ants. Spider mites can cause yellowing and stippling of leaves, while whiteflies can cause leaf drop. Thrips can cause stippling and distortion of leaves, and can spread diseases as they feed.
Management Strategies
The best approach to managing diseases and pests in Thunbergia bequaertii is to focus on prevention. Ensure that the plant is grown in well-draining soil and is not overwatered. Avoid overhead watering if possible. To control pests, consider using insecticidal soap or neem oil. Introducing beneficial insects like ladybugs can also help to control pests naturally. If a disease does develop, remove infected plant material promptly and dispose of it to prevent the spread of the disease. Fungicides may be necessary to control fungal diseases, but should be used sparingly and only as a last resort.
