Try to avoid placing the plant near drafts or air conditioning units, as this can cause temperature fluctuations that may harm the plant.
Soil Requirements
The soil used for Dichapetalum altescandens Engl. must be well-draining and rich in organic matter. A pH between 6.0-7.0 is ideal. This plant prefers slightly moist soil but will not survive in waterlogged conditions. A mixture of peat moss, perlite, and vermiculite is recommended.
It is important to note that Dichapetalum altescandens Engl. is a toxic plant and should be kept away from children and pets. It is essential to wear gloves when handling this plant, as its sap can cause skin irritation and even blindness if it comes in contact with the eyes.
Cultivation of Dichapetalum altescandens Engl.
The Dichapetalum altescandens Engl., also known as the green poison arrow plant, is a slow-growing plant that is native to West Africa. This plant grows well in warm temperatures and should be kept in an area that receives adequate sunlight. It is a fairly low-maintenance plant and can thrive in a variety of different soil types.
Watering Needs
The Dichapetalum altescandens Engl. should not be overwatered, as it prefers a drier soil. It is recommended to water this plant every two weeks, or when the top layer of soil has become dry to the touch. Overwatering can lead to root rot, and underwatering can cause the plant to become stressed and die.
Fertilization
It is recommended to fertilize this plant during the growing season, which typically runs from spring through fall. A balanced fertilizer such as a 10-10-10 or 20-20-20 can be used, and it should be applied every four weeks. Avoid fertilizing during the winter when the plant is dormant.
Pruning
Pruning of the Dichapetalum altescandens Engl. is not necessary, but it can help to shape the plant and promote fuller growth. Any dead or dying leaves should be removed as they appear to prevent the spread of disease. It is also recommended to prune any branches that are obstructing the plant's overall shape and structure.
Propagation of Dichapetalum altescandens Engl.
Dichapetalum altescandens Engl. is a flowering plant that is native to tropical regions of Africa. It can be propagated through several methods, including seeds, stem cuttings, and layering.
Propagation by Seeds
Seeds of Dichapetalum altescandens can be collected from the ripe fruit. The seeds can then be sown in well-draining potting soil in a container at a depth of about 1 inch. Keep the soil moist and warm, ideally between 70 to 85 °F, and you can expect germination in about 2-3 weeks. Once the seedlings have grown large enough, they can be transplanted to a larger container or planted outdoors.
Propagation by Stem Cuttings
Dichapetalum altescandens is also propagated through stem cuttings. Take cuttings from the stem in the spring, choosing healthy, young shoots. Cuttings should be about 6 inches long and should have some leaves attached. Remove the bottom leaves and dip the cut end of the stem in rooting hormone powder. Plant the stem in the well-drained potting soil, then water it well and cover the pot with a plastic bag to create humidity. Place the pot in a warm and bright spot, away from direct sunlight, and keep the soil moist. After about 6-8 weeks, the cuttings should have taken root; you can transplant the plants when they have grown large enough.
Propagation by Layering
Another method to propagate Dichapetalum altescandens is by layering, which involves placing a low-hanging stem of the plant in contact with soil so that it creates new roots. Choose a flexible stem and bend it downwards to the ground, keeping it in place with a small stake. Cover the part of the stem that is in contact with the soil. After a few weeks, roots should start to form. At this point, you can sever the new plant from the parent plant and transplant it.
