Propagation of Sterculia Lindensis Engl.

Sterculia Lindensis Engl. can be propagated through various methods such as seed propagation, vegetative propagation, root cuttings, and grafting.

Seed Propagation

Seed propagation is the most common method of propagating Sterculia Lindensis Engl. The most suitable time for seed collection is during the early part of the dry season. The collected seeds should be cleaned, dried in the sun for a few days and stored in a cool place until when ready to plant.

The planting process should start with the scarification of the seed coat to improve germination. This can be achieved by soaking the seeds in hot water for 24 hours. Alternatively, you can pour boiling water over the seeds and allow them to soak for 12 hours before planting. The seeds should then be sown in a well-drained nursery bed. After germination, the seedlings can be transplanted to individual pots or to the field.

Vegetative Propagation

Sterculia Lindensis Engl. can also be propagated vegetatively by stem cuttings. The cuttings should be taken from healthy and disease-free plants. The best time to take cuttings is during the wet season when the plant is actively growing. The cuttings should be about 10cm long, with at least two nodes and a few leaves.

The cuttings should be treated with rooting hormones and planted in a well-drained potting mix. Ensure that the cuttings are placed in a shaded area to prevent excessive drying. After rooting, the cuttings can be transplanted to individual pots or to the field.

Root Cuttings

An alternative method of vegetative propagation is through root cuttings. This method involves taking root cuttings from the parent plant and planting them in a well-drained medium. The cuttings should be about 10cm long and the diameter of a pencil. Ensure that the cuttings are placed horizontally in the soil and well-watered. The cuttings should be kept in a shaded area until when they start showing new growth.

Grafting

Grafting is another method of propagating Sterculia Lindensis Engl. This method involves joining a scion of the desired cultivar with a rootstock of a closely related species. The scion should be chosen from a healthy plant that is free from pests and diseases. The rootstock should be a strong, disease-resistant plant.

The graft union should be wrapped with grafting tape to hold it together. The grafted plant should be kept in a shaded area and watered regularly until when established.
