Cultivation of Strychnos angolensis Gilg var. tisserantii P.A.Duvign.
Strychnos angolensis Gilg var. tisserantii P.A.Duvign is a slow-growing, evergreen shrub or small tree, native to Africa. The plant prefers a warm and sunny climate, with temperatures between 20-30°C (68-86°F). The species can tolerate dry periods, but prefer a moderate amount of watering throughout the year.
Watering Needs
The plant requires moderate watering, and the soil should be kept slightly moist but not waterlogged. Water the plant deeply once a week during dry periods, and reduce watering during the cooler months.
Fertilization
Strychnos angolensis will benefit from an application of a balanced fertilizer once in the spring and once in the fall. Use a slow-release fertilizer with a nitrogen-phosphorus-potassium (NPK) ratio of 10-10-10 or 12-12-12.
Pruning
The shrub should be pruned annually to maintain its shape and size. Prune in the early spring before new growth appears. Remove any dead, damaged, or diseased branches, and thin out the older growth. Pinch back new growth to encourage branching and denser foliage. Keep the shrub at a height of 2-3m (6-10ft) through regular pruning.
Propagation of Strychnos angolensis Gilg var. tisserantii P.A.Duvign.
Strychnos angolensis Gilg var. tisserantii P.A.Duvign. can be propagated through different methods that include seed propagation, vegetative propagation, grafting, and air layering. Each method has its advantages and disadvantages, but the choice depends on the availability of the materials, the purpose of the propagation, and the level of expertise of the installer.
Seed propagation
The most common propagation method is by seeds since they are readily available, easier to handle, and cheaper. The seeds can be collected from mature fruits, which are small and orange when ripe. To improve the seed germination rate, the seeds must be extracted as soon as the fruits ripen, washed, and dried. The seeds can be sown in a nursery or directly in the field, but the nursery provides better control of the growth and development. When establishing a nursery, the seeds can be sown in well-prepared seedbeds and covered with a thin layer of soil. The ideal germination temperature is around 25-30°C, and the time for emergence is usually 4-5 weeks. The seedlings must be watered regularly and protected from pests and diseases.
Vegetative propagation
Another propagation method is by vegetative means that include stem cuttings, root cuttings, and sucker removal. The stem cuttings must be collected from a healthy and vigorous parent plant, preferably in the early morning or late afternoon. The cuttings must have at least two nodes and be 10-15 cm long. The lower leaves must be removed, and the cutting must be dipped in rooting hormone before planting. The cutting can be planted in a rooting medium such as sand, peat moss, or a mixture of both. The soil must be kept moist but not waterlogged, and the cutting must be protected from harsh sunlight and wind until they develop roots and new leaves. Root cuttings and sucker removal follow similar procedures as stem cuttings, but the former involves the removal of roots rather than stems, while the latter involves removing growing shoots that arise from the parent plant's base.
Grafting
Grafting is a more advanced propagation method that involves joining two different plant parts to create a single plant. This method is useful in propagating plants that are difficult to root or have desirable traits worth preserving. The plant's scion is the upper part that carries the desired traits, while the rootstock is the lower part that provides the root system. The two parts must be compatible, meaning that they must belong to the same plant family or genus. The graft union must be protected from moisture loss and pests until it establishes and heals.
Air layering
Air layering is a propagation method that involves creating a new plant by inducing roots on a stem while it is still attached to the parent plant. The method is useful for plants that are difficult to propagate by other methods, and it produces a clone of the parent plant. The stem to be layered must be healthy and flexible, and it must be wounded slightly at the point where roots are to form. A rooting hormone is applied to the wound, and a plastic wrap is tied around the wound to hold a handful of moist moss or other rooting medium. The wrapped up moss is then secured with string or rubber band. The moss is kept moist, and roots will develop within a few weeks. Once roots are well-developed, the new plant is cut off and transplanted.
Disease Management
The plant Strychnos angolensis Gilg var. tisserantii P.A.Duvign. is susceptible to several diseases that can significantly reduce its productivity. Below are some of the common diseases and ways to manage them:
- Leaf Spot: Leaf spot is caused by fungi, and it is characterized by the appearance of small, round, brown spots on the leaves. To manage it, you should remove and destroy infected leaves to prevent the spread of the disease. Also, avoid overhead watering, as this can facilitate the spread of the fungi.
- Root Rot: Root rot is usually caused by overwatering, and it can lead to the death of the plant. If you notice that your plant is showing signs of root rot, such as yellowing leaves and rotting roots, you should immediately reduce watering and improve the drainage of the soil.
- Powdery Mildew: Powdery mildew is a fungal disease that is characterized by the appearance of powdery white spots on the leaves. To manage it, you can apply a fungicide to the affected plant, or prune infected leaves to prevent the spread of the fungus.
Pest Management
Strychnos angolensis Gilg var. tisserantii P.A.Duvign. is also susceptible to several pests that can cause significant damage to the plant and reduce its productivity. Below are some of the common pests and ways to manage them:
- Spider Mites: Spider mites are tiny pests that commonly attack plants, and they can cause the leaves to turn yellow and fall off. To manage spider mites, you can apply insecticides, or use natural predators such as ladybugs. Alternatively, you can use neem oil, which is an effective and natural pest control method.
- Caterpillars: Caterpillars are common pests that can cause significant damage to the plant by feeding on the leaves. To manage them, you can physically remove them from the plant, or use an insecticide. A more natural approach is to introduce natural predators like birds and parasitic wasps.
- Mealybugs: Mealybugs are small, white, and fluffy pests that commonly attack indoor plants. They can cause significant damage to the plant by feeding on its sap. To manage mealybugs, you can use insecticides, alcohol, or a mixture of soap and water.
