Pruning of Deinbollia unijuga D.W.Thomas
Pruning Deinbollia unijuga D.W.Thomas is done primarily to maintain its shape and size. It is best to prune the plant after the blooming season to avoid interrupting the growth of its flowers. The plant should be pruned selectively, removing only damaged, diseased, or overgrown branches. Regular pruning encourages the growth of new branches and rejuvenates the plant.
Propagation of Deinbollia unijuga D.W.Thomas
Deinbollia unijuga D.W.Thomas, also known as "Tickle me Plant," can grow up to 8 meters tall and is native to tropical Africa. The plant is commonly grown for its ornamental foliage and fruit. Propagation of Deinbollia unijuga D.W.Thomas can be done through various methods:
Seed propagation
Seeds can be used for propagation of Deinbollia unijuga D.W.Thomas. The seeds should be collected from the ripe fruits, washed and sown in seed trays. It is important to note that the seeds should be sown as soon as possible after collection to ensure higher germination rates. The seedlings should be kept in a warm, humid and well-lit area.
Cutting propagation
Cutting propagation is another effective method that can be used to propagate Deinbollia unijuga D.W.Thomas. The cuttings should be taken from mature plants and should be 20-25cm with 2-3 leaves. A rooting hormone can be applied to the cuttings to increase the chances of successful growth. The cuttings should be planted in well-draining soil and kept in a warm and humid area.
Air layering propagation
Air layering propagation is a commonly used method to propagate Deinbollia unijuga D.W.Thomas. This method involves wounding a stem and then enclosing the wound with a moist rooting medium. The roots can grow out of the wound and into the rooting medium. Once roots have formed, the stem can be cut and planted in a well-draining soil mix.
Division propagation
Division propagation can also be used for Deinbollia unijuga D.W.Thomas. The plant can be divided into several parts, with each part having its root system, stem, and foliage. This method is best used for mature plants that have multiple stems.
Disease and Pest Management for Deinbollia unijuga D.W.Thomas Plant
Deinbollia unijuga D.W.Thomas is generally a low-maintenance plant that is not prone to disease and pest attacks. However, the following are some of the common diseases and pests that might affect the plant:

One of the common diseases that might affect Deinbollia unijuga D.W.Thomas plant is powdery mildew. Powdery mildew is a fungal disease that appears as a white powdery substance on the leaves, stems, and flowers of the plant. It can cause stunted growth, yellowing of leaves, and even death of the plant.
To manage powdery mildew, use a fungicide that contains potassium bicarbonate or neem oil. Regularly prune the infected parts of the plant and avoid watering the plant from above.
Common Pests
One of the common pests that might affect Deinbollia unijuga D.W.Thomas plant is mealybugs. Mealybugs are tiny insects that suck sap from the plant. They appear as white cottony masses on the leaves and stems of the plant. They can cause stunted growth, premature leaf drop, and even death of the plant.
To manage mealybugs, use a horticultural oil or insecticidal soap. Regularly prune the infected parts of the plant and avoid over-fertilization as it can attract mealybugs.
Another common pest that might affect Deinbollia unijuga D.W.Thomas plant is thrips. Thrips are tiny insects that suck sap from the plant. They appear as slender insects on the leaves and flowers of the plant. They can cause silvery patches on the leaves, stunted growth, and distortion of leaves and flowers.
To manage thrips, use an insecticide that contains spinosad or neem oil. Regularly prune the infected parts of the plant and avoid over-fertilization as it can attract thrips.
Regular monitoring of Deinbollia unijuga D.W.Thomas plant is essential in managing both diseases and pests. Early detection and treatment can save the plant from severe damage, thereby maintaining its vitality and beauty.
