In addition, prune some of the less productive branches to increase the yield of the tree. It is advisable to prune the Cola nut tree during the dormant season when it is not actively growing to reduce stress on the plant.
Propagation of Cola urceolata K.Schum.
Cola urceolata K.Schum. can be propagated through both sexual and asexual methods. However, due to the slow growth of the plant, asexual methods are preferred as they ensure that the new plants will have the same characteristics as the parent plant.
Asexual propagation
The two most widely used asexual propagation methods are cuttings and layering.
Cuttings propagation
Cuttings can be taken at any time during the growing season. Where possible, it is best to take softwood cuttings because they will root more easily and quickly. To propagate Cola urceolata K.Schum. using cuttings:
- Take a cutting about 5-10 cm long, making sure there is at least one node present.
- Strip off the leaves from the lower half of the cutting.
- Dip the cut end in rooting hormones.
- Plant the cutting in soil or a rooting medium.
- Keep the soil or rooting medium moist and warm.
- The new plant should start rooting after a few weeks.
Layering propagation
Layering is the process of encouraging a branch or stem to produce roots while still attached to the parent plant. It can be a good option for Cola urceolata K.Schum. because the plant's branches and stems tend to be quite flexible and easy to manipulate. To propagate Cola urceolata K.Schum. using layering:
- Identify a long, flexible stem that is low to the ground.
- (Optional) Gently scrape a part of the stem where you will encourage the development of roots.
- Ensure that the portion of the stem that has contact with the soil is about 10-15 cm long.
- Allow the plant to grow as usual, ensuring that the soil remains moist and free of weeds.
- The new plant should be well-rooted after a few months, once you are sure, sever the new plant from the parent.
Sexual propagation
If you do want to propagate Cola urceolata K.Schum. using sexual methods, collect the seeds when they are ripe and plant them in a soil or potting mix that has been prepared for them. Soaking the seeds in water can speed up the germination process. However, germination tends to be fairly low, and the plants can take up to six months to produce their first true leaves.
