Pruning
Inocarpus fagifer does not require heavy pruning, but minor pruning can help control its shape and size. Prune the tree during the dormant season to remove any dead, damaged, or diseased wood. Remove any weak branches that may not be able to support heavy fruit. You can also prune the tree to control its height or shape.
Overall, Inocarpus fagifer is a low-maintenance tree that can thrive in many different growing conditions. By following the above cultivation and care tips, you can enjoy a healthy, productive tree that provides both shade and delicious nuts.
Propagation methods for Inocarpus fagifer (Parkinson) F.R. Fosberg
Inocarpus fagifer, commonly known as the Tahitian chestnut, is a tropical tree species with edible nuts that are rich in nutrients. The species can be propagated through various methods ranging from vegetative to sexual propagation. The following are some of the common propagation methods for Inocarpus fagifer:
Seed propagation
Seed propagation is one of the common methods of propagating Inocarpus fagifer. The species produce seed pods that are brown and woody when mature. The seeds are black and relatively hard, and they take about 30-40 days to germinate.
Air-layering propagation
Air-layering propagation can also be used to propagate Inocarpus fagifer. The method involves girdling a branch and covering the wound with a rooting medium such as sphagnum moss or coconut coir. New roots will form at the point of the injury, and the branch can be cut and planted after a few months.
Cuttings propagation
Cuttings propagation can also be used to propagate Inocarpus fagifer. The method involves taking stem cuttings from the parent plant and rooting them in a suitable medium such as sand or vermiculite. The cuttings should be taken from healthy, disease-free parent plants, and the rooting medium should be kept moist but not waterlogged.
Budding propagation
Budding propagation is another method that can be used to propagate Inocarpus fagifer. The method involves grafting a scion (a small branch or twig) from a desirable cultivar onto a rootstock. The rootstock must be compatible with the scion for the grafting to be successful. Budding propagation is more complex and requires more skill and knowledge than other propagation methods.
In conclusion, Inocarpus fagifer can be propagated through different methods such as seed propagation, air-layering propagation, cuttings propagation, and budding propagation. The choice of propagation method will depend on the availability of plant materials, the resources, and the desired outcome.
