A soil pH of 6.0 to 7.0 is optimal for healthy growth. It is recommended to use a potting mix with equal amounts of sand, peat, and perlite for adequate drainage.
Cultivation Methods
Dichapetalum aurantiacum Engl., also known as "gifblaar" or "poison leaf," is a shrub-like plant that grows up to 2 meters tall. It can be cultivated in both garden settings and indoor settings as long as certain requirements are met.
It thrives in warm and humid environments and prefers soil that is well-draining, slightly acidic, and nutrient-rich. When transplanting the plant, it is essential to ensure that the new soil is similar to the plant's original soil, to avoid transplant shock.
Propagation can be achieved through seeds or cuttings. Seeds should be planted in a mixture of sand and soil, kept moist, and germinated in temperatures between 20-30°C. Cuttings can be taken in spring or summer and should be propagated in a moist environment with high humidity to promote faster rooting.
Watering Needs
Dichapetalum aurantiacum needs regular waterings, but the soil must be allowed to dry out somewhat before the next watering to avoid overwatering and root rot. It is crucial to water the plant deeply but infrequently to ensure sufficient moisture retention in the soil. Leaves should be kept dry when watering to prevent leaf rot and fungal infection.
Fertilization
Regular fertilization will promote the healthy growth of Dichapetalum aurantiacum. A fertilizer high in nitrogen and potassium is ideal for this plant, and it should be applied every two to three weeks during the growing season. It is essential to ensure that the soil is moisture-free and well-draining before fertilization to avoid harming the roots, and any excess fertilizer should be removed with water.
Pruning
Pruning is an essential aspect of the care of Dichapetalum aurantiacum. Pruning promotes growth, increases air circulation, and reduces the risk of the spread of disease. Pruning should only be done during the plant's dormant period, which is usually during the fall. Dead or diseased branches should be pruned immediately, and any branches that are growing inwards towards the center of the plant should be removed to increase air circulation. Overall, the aim of pruning is to promote the plant's natural shape while keeping it healthy and aesthetically pleasing.
Propagation of Dichapetalum aurantiacum Engl.
Dichapetalum aurantiacum Engl. can be propagated through both seeds and stem cuttings. Both methods have their advantages and disadvantages, and the choice of method will depend on the objectives of the grower.
Propagation by seeds
Seeds of Dichapetalum aurantiacum Engl. can be obtained from mature fruits. It is recommended to obtain fresh seeds and plant them immediately after collection. The seeds can be sown directly into a substrate, or they can be germinated in trays with appropriate substrate and then transplanted to individual pots. If sowing directly in a substrate or otherwise, the seeds should be planted superficially and covered with a thin layer of substrate.
Germination of Dichapetalum aurantiacum Engl. seeds can be slow and unpredictable. The seeds should be kept moist and warm, which can be achieved by covering the pots or trays with plastic wrap or using a propagator. The substrate should be well-drained, and it is recommended to use a mix of peat and perlite or vermiculite.
The seedlings can be transplanted to individual pots when they have developed a few true leaves. At this stage, they can be managed similarly to adult plants.
Propagation by stem cuttings
Dichapetalum aurantiacum Engl. can also be propagated by stem cuttings. This method usually produces faster and more uniform results than seed propagation.
The stem cuttings should be obtained from mature plants and should be at least 10 cm long. The lower leaves should be removed, and the cuttings should be allowed to dry for a few hours before planting. The cuttings can be planted directly into individual pots with an appropriate substrate or can be inserted into propagation trays or substrates.
The substrate should be well-drained, and it is recommended to use a mix of peat and perlite or vermiculite. The cuttings should be kept moist and warm, and it is recommended to cover them with plastic wrap or use a propagator. Rooting usually occurs in a few weeks.
The newly rooted plants can be transplanted to individual pots when they have developed a sufficient root system and a few new leaves. At this stage, they can be managed similarly to adult plants.
