Cultivation Methods
Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr. is a tropical plant that can be grown outdoors in warm regions with high humidity. The plant requires a well-draining soil mix that is rich in organic matter.
The plant prefers partial shade to full shade and can be grown in pots or planted directly in the ground. Make sure to plant the seedlings in a hole that is slightly larger than the root ball, and water the plant thoroughly immediately after planting.
Watering Needs
The plant needs to be watered regularly, but not excessively. Overwatering can lead to root rot, so it's important to allow the soil to dry out between waterings. Check the soil moisture level regularly and water the plant if the top inch of soil feels dry to the touch.
The amount of water required also depends on the location and climate. In areas with high humidity, the plant may require less frequent watering.
Fertilization
Fertilize Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr. every two to three months during the growing season with a balanced fertilizer. Be sure to follow the instructions on the label and avoid overfertilizing, as this can damage the plant.
Slow-release fertilizers can also be used, as they provide a steady supply of nutrients over a longer period of time.
Pruning
Pruning is not necessary for Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr., but it can be done to keep the plant compact and bushy. Pruning should be done in the spring or early summer before new growth starts.
Cut back any dead or diseased branches, and remove any branches that are crossing or rubbing against each other. Use clean and sharp pruning shears to prevent damage to the plant tissue.
Propagation of Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr.
Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr. is commonly propagated through vegetative methods, such as stem cuttings and layering, due to the challenges involved in propagating it using seeds. Although it can be propagated using seeds, sourcing the seeds is challenging and the germination process is complicated. Therefore, vegetative propagation is the preferred method.
Stem Cuttings
The stem cuttings method can be employed using a sharp and sterilized pruning shear or knife. For the best results, select a healthy plant with strong stems. Cut several sections of stem from the plant, each with a length of 10-15 cm. The stem cutting should have a minimum of two leaf nodes. Remove the leaves on the lower part of the stem cutting, leaving the upper part intact to support photosynthesis.
After removing the leaves, dip the cutting in a rooting hormone, which will help stimulate the growth of roots. Place the cutting in a pot filled with moist soil or a rooting medium such as vermiculite. Keep the soil or rooting medium consistently moist to ensure the growth of roots. In 3-5 weeks, roots should have emerged from the base of the stem cutting. Transplant the new plants into a pot filled with fertile and well-draining soil, suitable for the Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr.
Layering
Layering is another effective way to propagate Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr. To do this, locate a healthy plant with strong stems and choose a section of the stem that is touching the ground or close to it. Remove some of the leaves on the selected section of the stem, leaving a few leaves at the top to support photosynthesis. Bury the bottom part of the stem in the soil, ensuring that some leaves are still above the ground. Place a small stone on the buried section of the stem to hold it in place.
Water the soil around the buried part frequently to keep it moist. After some time, roots should have emerged from the buried section of the stem. At this point, cut the stem from the parent plant and transplant the new plant into a pot filled with fertile and well-draining soil.
Disease Management
Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr. can be susceptible to various diseases. The most common ones are fungal diseases such as leaf spot, powdery mildew, and anthracnose. To manage these diseases, it is essential to practice good sanitation by removing infected plants and debris. Also, ensure that the soil is well-drained and clean and avoid overhead watering. Fungicides such as copper-based products can also be used to manage these diseases.
Pest Management
Various pests can affect Tricalysia pobeguinii Hutch. & Dalziel var. pubescens Aubrév. & Pellegr. The most common ones are spider mites, scale insects, and mealybugs. To manage these pests, it is essential to practice good sanitation by removing infected plants and debris. Additionally, introducing beneficial insects such as ladybugs and lacewings can help manage these pests. In severe cases, insecticides such as neem oil or insecticidal soap can be used to manage these pests.
