A soil test can help determine the best fertilizer and application frequency.
Pruning
Pruning is essential for the proper growth and shape of the tree. Early pruning can help shape the plant to the desired form and prevent the formation of weak or damaged branches. Later, pruning should be done to remove dead, diseased, or damaged branches. It is recommended to prune the plant during the dry season, as pruning during the rainy season can lead to the growth of bacteria or fungi on the wounds of the plant.
Propagation of Castilla elastica Sesse ssp. costaricana (Liebm.) C. C. Berg
Castilla elastica Sesse ssp. costaricana (Liebm.) C. C. Berg, commonly known as the Panama rubber tree, is a species of evergreen tree that is native to Central America and southern Mexico. It is commercially important for its latex, which is used in the production of rubber-based products. Propagation of this plant can be done through several methods, including seed propagation, air layering, and grafting.
Propagation by Seed
Propagation of Castilla elastica Sesse ssp. costaricana by seed is straightforward. The seeds must be collected from mature trees, and after removal of the pulp, they can be sown immediately. The seeds should be sown in a well-draining soil mix that is kept moist at all times. They should be kept in a warm and humid environment for successful germination. Germination rates may vary, and it usually takes 2-3 years for the plant to reach maturity.
Propagation by Air Layering
Air layering is also a useful method of propagation for the Castilla elastica Sesse ssp. costaricana. This method involves the formation of roots on a stem while still attached to the parent plant. A section of the stem is slit, and rooting hormone is applied to the cut area. The slit area is then wrapped in a moist material, such as sphagnum moss. After a few months, roots will form on the cut area. The stem can then be cut off from the parent plant and potted in a well-draining soil mix.
Propagation by Grafting
Grafting is another propagation method that can be used for Castilla elastica Sesse ssp. costaricana. In this method, a scion from a desirable plant is grafted onto a rootstock from a hardy and disease-resistant plant. The scion is taken from a mature tree and must be compatible with the rootstock plant. Afterward, the graft is wrapped to keep moisture. The plant is then placed in a warm and humid environment to facilitate healing. Grafted plants usually grow faster and produce fruits and rubber latex much earlier than plants propagated by other methods.
