Light Requirements:
Triaspis emarginata De Wild. var. emarginata thrives when exposed to full sunlight. This plant requires at least six hours of direct sunlight each day. In case the plant is grown indoors, it should be placed near a south-facing window where it can receive enough sunlight.
Temperature Requirements:
Triaspis emarginata De Wild. var. emarginata can grow effectively in temperatures ranging from 15°C to 30°C. However, the plant may not survive under very low temperatures.
Soil Requirements:
The plant grows well in well-draining, rich soils. The ideal soil for Triaspis emarginata De Wild. var. emarginata is a mixture of sand, loam, and organic matter. The pH range for optimum growth of the plant is between 6.0 to 7.0.
Cultivation
Triaspis emarginata De Wild. var. emarginata, also known as the African milkberry, is a tropical plant that requires warm temperatures and high humidity to thrive. It grows best in well-draining soil, and the soil pH must be slightly acidic to neutral (between 5.5 and 7.0). The plant can be grown in pots or in the ground.
Watering Needs
African milkberry plants need consistently moist soil but must not be overwatered. Water the plant once the top inch of soil has dried out slightly but before it completely dries out. Avoid getting the leaves wet while watering to prevent leaf spots and other fungal diseases.
Fertilization
Fertilize the African milkberry with a balanced fertilizer every two weeks during the growing season. Reduce fertilization to once a month during the winter months. Use a fertilizer that is high in nitrogen to promote new growth and magnesium to prevent yellowing leaves.
Pruning
Regular pruning will help keep the African milkberry plant tidy and promote bushy growth. Pinch back the tips of the stem to encourage branching and remove any yellow or dead leaves. You can also prune the plant back by up to a third of its size to help control its overall size. Prune the plant during the growing season as the new growth will be quick to heal.
Propagation of Triaspis emarginata De Wild. var. emarginata
Triaspis emarginata De Wild. var. emarginata can be propagated through both seeds and cuttings. However, propagation through seeds is a little complex and time-consuming than cuttings.
Propagation through seeds
Seeds of Triaspis emarginata De Wild. var. emarginata are not easy to come by, as the plant produces fewer seeds. The seeds require proper preparation before sowing because they have a hard outer coating that needs to be broken down to enhance germination rates.
The seeds should first undergo an acid scarification process that helps breakdown the seed coat. This can be done by soaking the seeds in hot water (70–80°C) for about 10 minutes. Alternatively, one can soak the seeds in concentrated sulfuric acid for 20 minutes and then rinse thoroughly with water.
After breaking dormancy, sow the seeds in pots containing potting soil mixed with sand or perlite at a depth of about 2-3 times the diameter of the seed. Keep the soil moist by watering regularly and maintain a warm temperature of about 25-30°C. Germination of the seeds should take between 2-3 months.
Propagation through cuttings
Triaspis emarginata De Wild. var. emarginata can be easily propagated through stem cuttings.
To propagate using cuttings, select healthy young stems and make 10-15cm cuttings, ensuring that each cutting has at least two nodes. The lower pair of leaves should be removed, and the cutting base should be dipped in rooting hormone powder before planting in potting soil. Water the soil and cover the cutting with a transparent plastic bag to create a humid environment that will facilitate root formation. Ensure the soil is moist by watering regularly and place the cutting in partial shade. Rooting should occur after 3-4 weeks.
Once the cuttings have developed roots, transplant them into individual pots.
Disease and Pest Management for Triaspis emarginata De Wild. var. emarginata
Triaspis emarginata De Wild. var. emarginata is a hardy plant that is resistant to most pests and diseases. However, it can still be affected by a few illnesses and bugs. It is important to keep an eye out for any sign of disease or infestation to take timely actions.
Common Diseases
Leaf Spot: Leaf spots are caused by fungi that can cause yellowing and browning of the leaves. To control leaf spot, remove and destroy any infected leaves immediately and avoid over-watering the plant. Ensure good air circulation around the plant by pruning or spacing. Alternatively, you can also use a fungicide to spray the plant every two weeks until the disease is under control.
Root Rot: Root rot is caused by a waterlogged soil, which can lead to poor drainage. The roots will start to decay, causing the plant to wilt and eventually die. To prevent root rot, make sure to plant the Triaspis emarginata De Wild. var. emarginata in a well-draining soil mix and avoid over-watering. If the plant shows signs of root rot, remove the affected roots and repot the plant in fresh soil.
Common Pests
Aphids: Aphids are small, green insects that feed on the plant's sap, which can cause damage to the leaves and stem. To control the infestation, remove the aphids by hand or use a mild soap solution to spray the plant every few days until the infestation disappears. You can also introduce friendly predator insects to help control the population.
Spider Mites: Spider mites are tiny pests that can cause webbing on the leaves and stem of the plant. To control spider mites, spray the plant with a soapy water solution or an insecticide that is labeled for spider mites. Be sure to follow the instructions in the product label carefully to avoid harming the plant.
Overall, it is essential to have a regular maintenance routine for Triaspis emarginata De Wild. var. emarginata to avoid any potential diseases or pests. Keeping the plant healthy and stress-free is the key to preventing any infestation or illness.
