Cut back any dead or diseased branches first. Then, prune to shape the plant or reduce its size. The type of pruning depends on the desired shape, but it is recommended to not remove more than one-third of the plant's size in a single pruning event.
Propagation of Pavetta delagoensis Bremek.
Pavetta delagoensis Bremek. can be propagated by various methods, including:
Seed propagation
Seeds of Pavetta delagoensis Bremek. can be collected from the mature fruits. The seeds should be cleaned and sown in a well-draining potting mix. Keeping the soil moist is essential for the germination of seeds. The pot should be kept in a warm area with bright indirect sunlight. The seeds will normally germinate within two to four weeks of sowing.
Cuttings propagation
Pavetta delagoensis Bremek. cuttings can be taken from healthy parent plants. The cuttings should be taken from a healthy branch that is at least 10 centimeters long, and all the leaves except the top two should be removed. The cutting should be dipped in rooting hormone and planted in a well-draining potting mix. The pot should be kept in a warm area with bright indirect sunlight. The roots will normally form within six to eight weeks of planting.
Air layering propagation
Air layering is another propagation method that can be used for Pavetta delagoensis Bremek. This method involves making a small cut in the bark of a healthy branch and then wrapping the cut area with a moist sphagnum moss. The moss must be kept moist and covered with plastic wrap to create a humid environment. Roots will form inside the moss in two to three months of starting the layering process. Once roots develop, the branch can be cut from the parent and planted into a potting mix.
Regardless of the propagation method used, the new plants should be kept in a warm area with bright indirect sunlight. They should be kept moist, not waterlogged or allowed to dry out. Once established, they can be transplanted into their permanent location.
Disease Management for Pavetta delagoensis Bremek.
Like all plants, Pavetta delagoensis Bremek. is susceptible to various diseases such as:
- Leaf spots - caused by different fungal pathogens resulting in circular or irregularly shaped lesions on the leaves.
- Rust - this disease appears as yellow or brown pustules on the underside of the leaves which eventually causes the leaves to fall off prematurely.
- Powdery mildew - this is a fungal infection that affects the leaves and stems of the plant, causing a white powdery growth.
To manage these diseases, it is important to:
- Ensure proper plant nutrition and watering practices to maintain a healthy plant.
- Prune and remove infected plant parts as soon as they are noticed to prevent the spread of the disease.
- Use appropriate fungicides as recommended by a plant disease specialist.

- Caterpillars - can cause extensive damage to leaves by eating them.
- Aphids - small, pear-shaped insects that feed on the tips of leaves, leaving them distorted and stunted, and also excrete a sticky substance that can create fungal growth on leaves and other plant parts.
To manage pests, it is important to:
- Inspect the plants regularly for signs of pests and on the first sign of an infestation, take immediate action.
- Use appropriate insecticides as recommended by a plant pest specialist.
- Encourage natural predators such as ladybugs or lacewings which can help control pests.
