The fertilizer should be applied once a month, following the manufacturer's instructions, to avoid overfeeding the plants.
Pruning Convolvulus thomsonii Baker
Pruning of Convolvulus thomsonii Baker is not necessary but can help maintain the plant's shape and encourage more blooms. The plant can be pruned back by a third of its size in the late summer season to encourage more flowers.
The plant's dead flowers and stems can be removed throughout the growing season to improve the overall appearance of the plant.
Propagation of Convolvulus thomsonii Baker
Convolvulus thomsonii Baker, commonly known as Thai morning glory or Thomson's bindweed, is a beautiful ornamental plant due to its large, showy, and trumpet-shaped flowers. Propagation of Convolvulus thomsonii Baker can be done through several methods that include:
Seed Propagation
The most common method of propagation for Convolvulus thomsonii Baker is through seeds as it is the most straightforward and easiest method. The plant typically propagates through self-seeding in the wild. For cultivation, the seeds can be sown in spring or fall outdoors or in containers. The seeds should be surface sown and kept moist until germination, which can take one to two weeks. The seedlings can be transplanted once they have developed two to three true leaves.
Cutting Propagation
Propagation of Convolvulus thomsonii Baker through cuttings is also possible, but it is a bit more difficult as the plant is not a heavy rooting specimen. The best time for cutting propagation is in the late spring or early summer when the plant is actively growing. Take 3 to 4-inch-long cuttings from a healthy, mature plant, remove the bottom leaves, and dip the cut ends in rooting hormone. Place the cuttings in a potting mix, keep them moist and warm, and wait for roots to form, which can take several weeks. Once the plant is well-rooted, you can transplant it to a larger container or directly into the garden.
Division Propagation
Propagation of Convolvulus thomsonii Baker through division can be done in spring or autumn when the plant is actively growing. Divide the mature plants into several sections with roots attached using a sharp, sterile knife or a garden spade. Transplant the new divisions into fresh potting mix or directly into the garden. Ensure that the new divisions are kept well-watered until they become established.
Regardless of the propagation method that you choose, be sure to provide the plant with adequate sunlight, water, and nutrients to promote healthy growth. With proper care and attention, Convolvulus thomsonii Baker can add stunning beauty to your garden or indoor space for years to come.

Fortunately, there are ways to manage these issues and prevent them from destroying the plant entirely.
Common Diseases
Fungal diseases are the most common type of disease affecting Convolvulus thomsonii. Some of the most common fungal diseases include:
- Leaf spot: This appears as brown spots on the leaves and can eventually cause the leaves to fall off.
- Anthracnose: This causes the plant's foliage to wilt and die.
- Powdery mildew: This appears as a white powdery substance on the leaves and can cause them to become distorted, turn yellow, and eventually fall off.
To manage fungal diseases, it is recommended to keep the plant dry by avoiding overwatering and providing adequate spacing between plants for air circulation. If disease is detected, remove infected foliage and treat the plant with a fungicide.
Common Pests
Convolvulus thomsonii is also susceptible to pests that can damage or kill the plant. Some of the most common pests that affect this plant include:
- Aphids: These are small, soft-bodied insects that feed on the sap of the plant and can cause yellowing and distortion of the leaves.
- Spider mites: These are tiny pests that live on the undersides of the leaves and feed on the plant's sap, eventually causing yellowing and drying of the leaves.
- Thrips: These are narrow insects that cause silvery or brownish scars on the leaves.
To manage pest infestations, it is recommended to regularly inspect the plant for signs of pests, such as yellow leaves or webbing. Prune and dispose of infested plant parts and use insecticidal soap or Neem oil to control the pest population.
By following these disease and pest management strategies, you can increase the likelihood of Convolvulus thomsonii growing and thriving in your garden or landscape.
