General Appearance

Scolopia engleri Gilg is a deciduous tree that grows up to 15 meters tall. It has a dense, spreading crown and a straight, cylindrical trunk that can have a diameter of up to 60 cm. The bark of the tree is rough, dark gray or brown, and fissured. The leaves are alternate, elliptical to oblong in shape, and have a glossy dark green color on the upper surface and a lighter color on the underside. The tree bears small, greenish-white flowers that are borne in clusters on the branches. The fruit is a red to dark purple drupe, which is edible but is often sour and astringent in taste.

Light Requirements

Scolopia engleri Gilg generally requires full sunlight exposure for healthy growth. The plant grows best in areas with unobstructed sunlight, but it can tolerate partial shade in the afternoon. Insufficient light can cause slow growth and weakened stems, resulting in stunted development and reduced fruit production.

Temperature Requirements

The ideal temperature range for Scolopia engleri Gilg is between 20°C to 28°C. The plant thrives in warm to hot climates and does not tolerate cold temperatures. Temperatures below 15°C can cause severe damage to the plant's leaves, branches, and stems, leading to complete decline in unfavorable conditions.

Soil Requirements

Scolopia engleri Gilg grows best in fertile, well-drained soils. The ideal soil pH level for the plant is between 5.0 and 6.5, which is slightly acidic. The plant can tolerate a wide range of soil textures, but it prefers sandy loams or rocky soils. The soil should be rich in organic matter and nutrients, which can promote healthy growth and strong roots.

Cultivation of Scolopia Engleri Gilg

The Scolopia Engleri Gilg is an evergreen tree with a moderate growth rate. It is native to the tropical regions of Africa, where it grows in dense forests and woodlands.

The plant prefers well-drained soils that are rich in organic matter. The pH of soil for Scolopia Engleri Gilg should ideally be between 5.5 and 6.5.

The plant can be propagated either by seeds or cuttings. However, it is easier to propagate it from cuttings.

Watering Needs of Scolopia Engleri Gilg

Scolopia Engleri Gilg prefers moderately moist soil. The plant requires regular watering, especially during the first few years of growth. However, it is important not to let the roots sit in water or waterlog the soil.

During the dry seasons, the plant needs more water, and when the soil on top becomes slightly dry, it is time to water it. Overwatering can lead to root rot and cause harm to the plant.

Fertilization of Scolopia Engleri Gilg

The Scolopia Engleri Gilg requires regular fertilization to grow well. Using organic fertilizer is the best, and it should be applied at least once every month during the growing season.

However, one should be careful not to apply too much fertilizer as it can lead to salt build-up in the soil, which in turn leads to root damage or death.

Pruning of Scolopia Engleri Gilg

Pruning of the Scolopia Engleri Gilg should be done to maintain its shape and size, especially in the early years of growth. The pruning should be done after the plant has flowered or during the dry season.

Any weak branches, dead, or diseased branches should be carefully removed as they can harm the plant. Pruning cuts should be made just above the bud, and the cut surface should be treated with fungicide to prevent infections.

Propagation of Scolopia engleri Gilg

Scolopia engleri Gilg is commonly propagated by both seed and cuttings. The propagation process can be done in a greenhouse or outdoors through direct seeding. The following are the methods for propagating Scolopia engleri Gilg:

Propagation by Seed

The following are the steps for propagating Scolopia engleri Gilg by seed:

1. Collect ripe fruits from the plant during the fall season. The fruits are typically reddish-purple and are about 1.5 cm in diameter.
2. Extract the seeds from the fruits and remove the pulp.
3. Clean the seeds with water and dry them for two days in a well-ventilated area.
4. Prepare a seedbed that is rich in organic matter.
5. Sow the seeds in the seedbed at a depth of 1-2 cm and cover them with soil.
6. Water the seedbed regularly to keep it moist, but not waterlogged.
7. The seeds will germinate within two months.
8. Transplant the seedlings to individual pots when they have grown four true leaves.
9. Maintain the seedlings in a greenhouse or protected environment for six months before transplanting them into their final location outdoors.

Propagation by Cuttings

The following are the steps for propagating Scolopia engleri Gilg by cuttings:

1. Take cuttings in the early spring from the current season's growth.
2. Cut a 10-15 cm stem from the parent plant.
3. Remove all the leaves except for the top 2-3 leaves.
4. Dip the cut end of the stem in rooting hormone powder.
5. Prepare a rooting medium that is a mix of peat moss and perlite.
6. Insert the cutting into the rooting medium and water it.
7. Cover the cutting and container with clear plastic.
8. Place the container in a shaded area where the temperature is around 21°C.
9. Mist the cutting regularly and remove any dead leaves.
10. The cutting will root within 3-4 weeks.
11. Transplant the cutting to individual pots and maintain the cutting in a greenhouse or protected environment for six months before transplanting it into its final location outdoors.

Disease and Pest Management for Scolopia engleri Gilg Plant

Scolopia engleri Gilg, also known as African cherry, is susceptible to different pests and diseases that can adversely impact the plant's growth and productivity. Here are some of the common pests and diseases that might affect the Scolopia engleri Gilg plant, along with suggested ways of managing them:

Pests

Mealybugs: These soft-bodied, white insects feed off the sap of plants, weakening them. Signs of a mealybug infestation include sticky leaves and a white, cotton-like substance that clusters beneath leaves and along the stem. To manage the infestation, spray the plant with rubbing alcohol and water.

Scale insects: Scale insects are small, hard, and dome-shaped, and they reproduce quickly. You can identify them by the small bumps on the stems or leaves, and the sticky substance they produce. To get rid of the scale insects, use a cotton swab soaked in rubbing alcohol and water and swab the insects off the leaves and stem.

Diseases

Anthracnose: This fungal disease often affects African cherry's leaves, causing brown or black spots and leading to leaf drop. To manage this disease, prune infected leaves, improve air circulation, and avoid overhead watering.

Root Rot: Root rot is a bacterial disease caused by poor soil drainage. The disease leads to the death of the plant's roots, weakening the plant, and causing it to die eventually. To prevent root rot, ensure proper drainage and avoid overwatering.

Powdery Mildew: Powdery mildew appears as a white powdery substance on the leaves, leading to leaf curling and shedding. To manage the disease, prune affected leaves and use a fungicide to control further spread.

By taking care of the plants and ensuring that any pest or disease problems are quickly identified and addressed, you can successfully grow and maintain Scolopia engleri Gilg plants.
