When planting Solanum bequaertii De Wild., it is important to space the plants at least two feet apart to allow room for growth. The plant should be planted at the same depth as it was in the pot or nursery container. After planting, water the plant thoroughly to help it establish roots.
Watering Needs for Solanum bequaertii De Wild.
Solanum bequaertii De Wild. requires regular watering, especially during the first year of growth. Water the plant deeply once a week during dry periods, but avoid overwatering. Overwatering can cause root rot, which can kill the plant.
During the second year of growth, Solanum bequaertii De Wild. can tolerate periods of drought. However, it is still important to water the plant deeply during extended dry periods. It is also important to water the plant in the morning to allow the leaves to dry before nightfall to prevent fungal diseases.
Fertilization for Solanum bequaertii De Wild.
Solanum bequaertii De Wild. benefits from regular fertilization to promote growth and flowering. A balanced fertilizer with equal amounts of nitrogen, phosphorous, and potassium can be applied every two to three months during the growing season.
Compost or well-rotted animal manure can also be used to fertilize Solanum bequaertii De Wild.. Spread a thin layer of compost or manure around the base of the plant, being careful not to touch the stem. Water thoroughly after applying compost or manure.
Pruning Solanum bequaertii De Wild.
Solanum bequaertii De Wild. requires minimal pruning. The plant naturally grows into a compact, rounded shape. However, if the plant becomes too leggy or unruly, pruning can be done in early spring before new growth appears.
When pruning, use clean, sharp pruning shears and make cuts at a 45-degree angle just above a bud or leaf. Remove any dead, damaged, or diseased branches as well as any branches that are crossing or rubbing against each other.
Propagation of Solanum bequaertii De Wild.
Solanum bequaertii De Wild. can be propagated by seed and cuttings. However, propagation by seed is the most commonly used method.
Propagation by seed
The seeds of Solanum bequaertii De Wild. are obtained from the fruits of the mature plant. It is essential to select fresh, ripe and healthy seeds for successful propagation. The seeds are extracted from the fruits, dried and stored in cool, dry conditions to prevent loss of viability. Before sowing, the seeds are treated with a suitable fungicide to prevent fungal infections. The seeds can be sown directly in the field or in containers in a greenhouse or nursery.
If sowing directly in the field, it is important to ensure that the soil is well-drained and moist. The seeds are sown at a depth of about 1 cm and covered with soil. The seedlings typically emerge within 2-4 weeks.
When propagating in a greenhouse or nursery, the seeds are sown in trays or pots filled with a suitable seed bed mix. The seeds are covered with a thin layer of soil and watered lightly. The trays or pots are covered with a clear plastic cover to maintain humidity. The seedlings typically emerge within 1-2 weeks. Once the seedlings have developed 2-4 true leaves, they are transplanted into larger containers or directly into the field, depending on preference and availability.
Propagation by cuttings
Solanum bequaertii De Wild. can be propagated by stem cuttings, although this method is not as common as seed propagation. The cuttings are obtained from healthy, mature plants and should be about 10-15 cm long with 2-3 nodes. The bottom leaves are removed, and the cuttings are dipped in a rooting hormone to encourage root growth. The cuttings are then planted in a suitable rooting medium, such as a mixture of peat moss and perlite. The cuttings are watered lightly and placed in a shaded area. The rooting process typically takes 4-6 weeks. Once the cuttings have developed a strong root system, they can be transplanted into larger containers or directly into the field.
Disease Management for Solanum bequaertii De Wild.
Like all other plants, Solanum bequaertii is vulnerable to a wide range of diseases caused by fungi, bacteria, and viruses. Below are some common diseases that affect Solanum bequaertii and ways to manage them:
Early Blight
Early blight is a fungal disease that causes circular lesions on the leaves of plants. These lesions often have a target-like appearance and can cause premature leaf drop. To manage early blight, avoid overhead watering and remove any infected leaves. Fungicides containing copper or sulfur can be used to control the disease.
Verticillium Wilt
Verticillium wilt is a fungal disease that causes leaves to yellow and wilt. It can also cause stem discoloration and dieback. To manage Verticillium wilt, avoid planting in areas where the disease has occurred before. Fungicides are not very effective in controlling the disease, so removing the infected plant is the best course of action.
Mosaic Virus
Mosaic virus is a viral disease that causes mottled leaves with yellow and green patterns. It can also stunt plant growth and reduce yields. Unfortunately, there is no cure for the mosaic virus. The best course of action is to remove infected plants and plant healthy ones.
Pest Management for Solanum bequaertii De Wild.
Like most members of the Solanaceae family, Solanum bequaertii is vulnerable to many pests, including insects and mites. Below are some common pests that affect Solanum bequaertii and ways to manage them:
Spider Mites
Spider mites are tiny pests that can be difficult to detect until they have caused significant damage. They suck sap from the undersides of leaves, causing them to yellow and eventually drop. To manage spider mites, keep the plants well watered and wash them regularly with a strong spray of water. In severe cases, insecticidal soap or horticultural oil may be needed.
Whiteflies
Whiteflies are small, winged insects that suck sap from the leaves, causing them to yellow and wilt. They can also transmit diseases between plants. To manage whiteflies, keep the plants well-watered and wash them regularly with a strong spray of water. In severe cases, insecticidal soap or horticultural oil may be needed.
Tomato Hornworms
Tomato hornworms are large green caterpillars that can quickly strip plants of their leaves and fruit. They can be picked off by hand or sprayed with Bacillus thuringiensis (Bt), a biological insecticide. An organic option is to plant companion plants such as marigolds that can help deter the pests.
