Pruning of Manulea Platystigma Hilliard & B.L.Burtt
The Manulea Platystigma does not require a lot of pruning. However, it is advisable to remove any dead or diseased parts of the plants regularly. Pruning will also encourage new growth and flowering.
You can prune the plant after flowering has ended in late Summer or early Autumn. You can also pinch back the stems during the growing season to promote bushier growth. Always use a clean and sharp pair of pruning shears and disinfect them before pruning the plant.
Propagation of Manulea Platystigma
Manulea Platystigma can be propagated through seeds, cuttings, and division. The following methods can be used to propagate the plant:
Seed Propagation
The seeds of Manulea Platystigma need to be sown in well-draining soil during spring or early autumn. The soil should be carefully prepared, and the seeds should be sown at a shallow depth. The seedlings should be watered regularly and kept in a partially shaded area until they have grown to a suitable size to be transplanted.
Cuttings Propagation
Cuttings of Manulea Platystigma can be taken from the softwood in late spring or summer. The cuttings should be 10-15cm long and should be taken from the healthy parts of the plant. Remove any leaves from the bottom of the cutting, and dip the cut end of the stem in rooting hormone before planting in well-draining soil. The cuttings should be kept in a shaded area and kept moderately moist until roots develop. Once the roots have developed, they can be transplanted into larger pots or directly into the ground.
Division Propagation
The division of Manulea Platystigma can be done during spring. The plant should be carefully dug out of the ground and the roots separated into smaller sections. Each section should have a healthy amount of leaves and roots. Replant each division in a new location and water regularly until established.
Disease Management
Manulea platystigma is a hardy plant that is not often affected by diseases. However, just like other plants, it is vulnerable to fungal and bacterial infections. Here are some of the common diseases that can affect the plant:
- Crown Rot: This disease is caused by a soil-borne fungus and can lead to the rotting of the plant's crown. The affected plants should be removed, and the soil should be treated with appropriate fungicides before planting new seedlings.
- Leaf Spot: Leaf spot is caused by a fungus and appears as small, circular, brown spots on the leaves. To manage this disease, infected leaves should be removed, and the plant should be sprayed with a fungicide. It is also essential to maintain good plant hygiene.
- Powdery Mildew: Powdery mildew is a fungal disease that appears as a white powdery coating on the leaves. To manage this disease, affected leaves should be removed, and the plant should be regularly sprayed with fungicide. It is also crucial to ensure proper air circulation and avoid watering the plant late in the day.
Pest Management
Manulea platystigma is relatively pest-resistant. However, it can still be attacked by pests, mainly if grown in a garden or farm setting. Here are some of the common pests that can affect the plant:
- Aphids: Aphids are tiny, soft-bodied insects that suck sap from the plants, leading to stunted growth. To manage them, spray the plant with insecticidal soap or neem oil.
- Spider Mites: Spider mites are tiny arachnids that often appear as small red or black dots on the leaves. To manage them, treat the plant with miticide or remove infected leaves. It is also essential to maintain proper plant hygiene.
- Whiteflies: Whiteflies are small insects that often appear as tiny white or yellowish specks on the leaves. They suck sap from the plant, leading to a weakened immune system. To manage them, spray the plant with insecticidal soap, neem oil, or a solution of water and dish soap.
Regular inspection of the plant can help in identifying pests and diseases and take quick action to manage them. Good plant hygiene and proper cultural practices, such as adequate watering and fertilization, can also help to keep the plant healthy and less vulnerable to pests and diseases.
