Cultivation of Coccinia rehmannii Cogn. var. littoralis A.Meeuse
Coccinia rehmannii Cogn. var. littoralis A.Meeuse is a tropical plant that requires warm temperatures to grow well. You must select a site with enough sunlight for at least six hours a day and well-draining soil. The plant requires shelter from strong winds and heavy rainfall, which means planting it close to other tall plants or near a fence can be an excellent idea.
Watering Needs
Water the plant regularly, especially during the dry months or when there is inadequate rainfall. Ensure that the soil remains moist but not waterlogged. Avoid spraying too much water on the leaves as it can cause them to rot.
Fertilization
Fertilize the plant using a slow-release fertilizer at the beginning of each growing season. The fertilizer should have a balance of nitrogen, phosphorus, and potassium. You may also add organic matter to the soil to improve its fertility levels.
Pruning
Pruning is necessary to control the size and shape of the plant. You can do it at any time of the year, but the best time is during the dormant season. Remove any dead, diseased, or damaged parts of the plant. It is also necessary to cut back old shoots to encourage new growth.
Propagation of Coccinia rehmannii Cogn. var. littoralis A.Meeuse
There are two common methods of propagating Coccinia rehmannii Cogn. var. littoralis A.Meeuse. These are:
Seed propagation
