The plant thrives in areas with full sunlight to partial shade. It can be propagated using seeds or stem cuttings.
Watering Needs
Solanum dasyphyllum Schumach. & Thonn. var. decaisneanum Bitter prefers moderate watering with a deep soak once a week during the growing season. However, during dry periods, it may require more frequent watering to keep the soil moist.
Fertilization
It is recommended to fertilize the plant during its active growing season from spring to summer. A blend of organic and inorganic fertilizers can be used. Apply the fertilizer every four to six weeks, following the manufacturer's instructions. Overfertilization can result in excessive growth and poor fruit production.
Pruning

Propagation of Solanum dasyphyllum Schumach. & Thonn. var. decaisneanum Bitter
Solanum dasyphyllum Schumach. & Thonn. var. decaisneanum Bitter, commonly known as African eggplant or bush tomato, can be propagated through several methods:
Seed Propagation
The plant produces fruits that contain numerous small seeds. To propagate the plant using seeds, start by harvesting the matured fruits. Once the fruits are harvested, remove the seeds from them and clean them with water to remove any debris.
Next, sow the seeds in well-draining soil and cover with a thin layer of soil. Water the soil lightly and keep it moist until germination occurs. The seeds usually take about two weeks to germinate.
Cuttings
The plant can also be propagated through stem cuttings. To propagate the plant using cuttings, take cuttings from healthy plants. Cut a healthy stem that has at least two nodes and removes the leaves from the bottom node.
Next, dip the cuttings in rooting hormone powder and plant them in well-draining soil. Keep the soil moist and place the cuttings in a shaded area to protect them from direct sunlight. After about four weeks, the cuttings should have developed roots and can be transplanted to their permanent location.
Air Layering
Another propagation method for Solanum dasyphyllum Schumach. & Thonn. var. decaisneanum Bitter is air layering. This method involves selecting a healthy stem and stripping a ring of bark from the stem about 10 cm from the tip. Apply rooting hormone powder to the exposed area and wrap it with damp sphagnum moss and plastic wrap. After a few weeks, roots should have developed from the exposed area. Cut off the rooted section and plant it in well-draining soil.
Disease Management
Solanum dasyphyllum Schumach. & Thonn. var. decaisneanum Bitter is highly susceptible to fungal diseases such as powdery mildew, downy mildew, and leaf spot. To manage these diseases, it’s important to keep the plants as clean and dry as possible. Remove any dead or diseased plant tissue promptly. Avoid overhead watering and ensure good air circulation around the plants.
Organic fungicides such as copper-based sprays may be used to manage fungal diseases. However, it’s important to follow the directions carefully and apply them at the first sign of disease.
Another effective way to manage fungal diseases is by using preventive measures. Practicing crop rotation, selecting disease-resistant varieties, and keeping tools and equipment clean can prevent the spread of fungal diseases.
Pest Management
Common pests that affect Solanum dasyphyllum Schumach. & Thonn. var. decaisneanum Bitter include spider mites, aphids, and whiteflies. These pests can cause leaves to yellow and wilt, and may even kill the plant if left untreated.
To manage these pests, insecticidal soaps or oils may be used. These are effective against soft-bodied insects like aphids and whiteflies, but may not be as effective against spider mites. If using insecticides, it’s important to follow the directions carefully and avoid spraying when the temperature is too hot.
Natural predators such as ladybugs, lacewings, and parasitic wasps can also be introduced into the garden to control pest populations. It’s important to avoid using broad-spectrum pesticides that can kill these beneficial insects.
Good cultural practices such as removing weeds and debris from around the plants, and keeping the area clean can also help prevent pest infestations. Additionally, using row covers or netting can physically prevent pests from reaching the plants.
