Propagation of Xeromphis obovata (Hochst.) Keay
Xeromphis obovata, commonly known as the Indian Wild Plum, is a small deciduous tree belonging to the family Rubiaceae. The tree is native to India, Sri Lanka, and Myanmar. It has blooming white flowers, and the plum-like fruits of the tree are edible and used in traditional medicine.
The plant can be propagated through various methods, including:
Seed Propagation
The seeds of Xeromphis obovata are viable and can be sown for propagating the plant. The seeds should be collected from ripe fruits and sown in the soil during spring. The soil should be moist and well-drained. The seeds will germinate in 15 to 20 days, and the young seedlings can be transplanted to a larger pot or container when they have 2-3 pairs of true leaves.
Cuttings Propagation
The plant can also be propagated by stem cuttings collected from a healthy and mature tree. The cuttings should have a length of 10-15 cm and must be taken from semi-hardwood with a diameter of 0.5-1 cm. The cuttings should be planted in well-drained soil with ample moisture and should be kept in shade. The cutting will develop roots in 5-6 weeks, and it can be transplanted to a larger pot or container after 3-4 months.
Air Layering
Air layering is one of the effective propagation methods for Xeromphis obovata. A healthy and mature branch of the tree should be selected for air layering. A section of the branch should be removed, and a 2-3 cm wide strip of bark should be peeled off from the stem. The exposed region should be kept moist with sphagnum moss, and it should be wrapped with plastic or polythene. After a few weeks, roots will develop at the cut area. The rooted portion can be separated from the mother plant and planted in a pot or container.
Propagation of Xeromphis obovata through these methods requires patience, proper care, and attention to the plants. By following the correct steps and techniques, one can successfully propagate the plant for gardening or plantation purposes.
Disease and Pest Management for Xeromphis obovata (Hochst.) Keay

To manage this disease, it is important to remove and destroy the infected leaves. One can also use fungicides to control the disease.
Rust: Rust is another fungal disease that can affect the leaves of Xeromphis obovata. It is caused by the fungus Puccinia xeromphicola and appears as rusty brown spots on the leaves. To manage this disease, it is important to remove and destroy the infected leaves. One can also use fungicides to control the disease.
Root Rot: Root rot is a fungal disease that affects the roots of Xeromphis obovata. It is caused by the fungus Phytophthora sp. and occurs due to overwatering or poor drainage. One can manage this disease by improving the drainage in the soil and avoiding overwatering. Fungicides can also be used to control the disease.
Common Pests
Scales: Scales are small, oval-shaped insects that suck the sap out of the leaves and stems of Xeromphis obovata. They appear as small bumps on the plant and can cause yellowing and stunted growth. To manage scales, one can use insecticidal soap or neem oil.
Aphids: Aphids are small, pear-shaped insects that feed on the sap of Xeromphis obovata. They also secrete a sticky substance called honeydew, which attracts ants. To manage aphids, one can use insecticidal soap or neem oil. Natural predators such as ladybugs and lacewings can also be introduced to control the aphids.
Spider Mites: Spider mites are tiny, red insects that suck the sap out of the leaves of Xeromphis obovata. They can cause yellowing and tiny webs on the leaves. To manage spider mites, one can use insecticidal soap or neem oil. Natural predators such as predatory mites can also be introduced to control spider mites.
By taking proper care of the plant and promptly managing any diseases or pests, one can ensure the healthy growth and yield of Xeromphis obovata.
