4. Once the seedlings have grown large enough, they can be transplanted to a larger pot or directly into the garden.

Propagation by cuttings:

Although Trichilia redacta is primarily propagated through seeds, some cultivars can also be grown from cuttings. Here are the steps for propagating the plant using cuttings:

1. Take a cutting that is about 10 cm long from a mature plant, making sure to make a clean cut.
2. Remove the leaves from the lower half of the cutting.
3. Dip the cut end of the cutting in rooting hormone powder, tapping off any excess powder.
4. Plant the cutting in a pot filled with a well-draining soil mix. The soil should be moist but not waterlogged.
5. Cover the pot with a plastic bag to maintain high humidity levels.
6. Place the pot in a warm and brightly lit area, avoiding direct sunlight.
7. After six to eight weeks, the cutting should have rooted and can be transplanted into a larger pot or directly into the garden.

By following these propagation methods, you can easily propagate Trichilia redacta Burtt Davy & Bolton to enjoy this beautiful plant in your home or garden.

Common Diseases:

One of the most common diseases that could affect Trichilia Redacta is Powdery Mildew. Powdery Mildew is a fungal disease that appears as a white, powdery coating on the leaves and stems of the plant. It can lead to stunted growth, reduced yield, and even death. To manage Powdery Mildew, it is recommended to remove and destroy infected plant parts immediately. You can also use a fungicide such as sulfur or neem oil to control the disease.

Another disease that could affect Trichilia Redacta is Leaf Spot. Leaf Spot is also a fungal disease that appears as small, circular spots on the leaves of the plant. It can cause the leaves to turn yellow and fall off prematurely. To manage Leaf Spot, it is recommended to remove and destroy infected plant parts and also to make sure that the plant is not overwatered. You can also use a fungicide to control the disease.

Common Pests:

One of the most common pests that could affect Trichilia Redacta is the Scale Insect. Scale Insects are small, oval-shaped insects that attach themselves to the plant and suck its sap, which can lead to stunted growth and reduced yield. To manage Scale Insects, it is recommended to use a horticultural oil spray or a soapy water solution to remove the insects from the plant. You can also introduce natural predators such as ladybugs or lacewings to the plant.

Another pest that could affect Trichilia Redacta is the Mealybug. Mealybugs are also small, oval-shaped insects that appear as white, cottony masses on the plant. They also suck sap from the plant and cause stunted growth and reduced yield. To manage Mealybugs, it is recommended to use a horticultural oil spray or a soapy water solution to remove the insects from the plant. You can also introduce natural predators such as ladybugs or lacewings to the plant.

Overall, managing pests and diseases in Trichilia Redacta involves a combination of good cultural practices such as proper watering and pruning, and also the use of natural or chemical control methods.
