Watering Needs
Although Capparis holliensis A.Chev. is drought-resistant, it requires sufficient watering during the first year of planting to establish roots. After that, watering requirements reduce, and the plant can survive with minimal watering. Watering should be carried out at the base of the plant to avoid rotting of stems and leaves. Since it is tolerant of dry spells, the plant does not require frequent watering.
Fertilization
Fertilization should be done before planting, at the time of planting and during the plant's growing period. The best-suited fertilizer for Capparis holliensis A.Chev. is compost manure.

Pruning
Capparis holliensis A.Chev. requires minimal pruning, and pruning should only be carried out to remove the dead or damaged branches. Pruning should not be carried out during the plant's dormant season. Instead, pruning should be carried out just before the growing season begins to allow for new growth and to shape the plant to the required form. It is preferable to use sharp pruning tools to avoid damaging the plant and spreading diseases.
Propagation of Capparis holliensis A.Chev.
Capparis holliensis A.Chev. can be propagated by seeds or cuttings.
Seed Propagation
Seeds of Capparis holliensis A.Chev. are collected from mature fruits and washed to remove the pulp. After washing, the seeds are planted in pots filled with well-drained soil and placed in a shaded area. Germination usually occurs within 2-3 weeks, and the seedlings can be transplanted into individual containers when they reach a height of at least 10cm.
Cutting Propagation
Cuttings of Capparis holliensis A.Chev. can be taken from mature plants during the rainy season. The cuttings should be about 20cm long and 5-6mm in diameter, and should be taken from the top of the plant. The leaves on the lower half of the cutting are removed, and the cutting is dipped in rooting hormone and planted in well-drained soil. The cuttings should be watered regularly, and should be kept in a shaded and humid area until roots develop, which usually takes about 4-6 weeks. Once the cuttings have developed roots, they can be transplanted into individual containers.
Disease and Pest Management for Capparis holliensis A.Chev.
Capparis holliensis A.Chev., commonly known as the bush caper, is a shrub species that is endemic to Africa. Like all plants, it is susceptible to diseases and pests that can damage its growth and yield. To ensure healthy growth and a good yield, it is essential to implement proper disease and pest management strategies. Here are some common diseases and pests that may affect Capparis holliensis A.Chev., along with their management.
Diseases
Fungal Diseases: Capparis holliensis A.Chev. can be affected by fungal diseases such as powdery mildew, leaf spot, and blight. Powdery mildew appears as a white powdery growth on the leaves and is caused by a fungus. Leaf spot causes small circular spots on the leaves, which can eventually lead to defoliation if left unchecked. Blight is a fungal disease that affects the stems and leaves of the plant, causing rotting and discoloration.
Management: To manage fungal diseases, regular inspection of the plant is essential. If detected early, powdery mildew and leaf spot can be treated by removing the infected parts and applying a copper-based fungicide. For blight, it is recommended to remove the infected parts of the plant and apply a copper-based fungicide immediately. To prevent fungal diseases, ensure adequate ventilation, and avoid wetting the leaves during irrigation.
Pests
Insects: Capparis holliensis A.Chev. can be attacked by various insects, such as aphids, whiteflies, and mites. These pests feed on the sap of the plant and can cause wilting and stunted growth.
Management: Regular inspection of the plant is important to detect any insect infestations. To control insect pests, it is recommended to use insecticidal soaps or oils, which are eco-friendly and safe to use. It is essential to follow the instructions on the label and apply at the recommended rate. To prevent insect infestations, promote natural predators such as ladybirds, lacewings, and hoverflies.
Vertebrates: Capparis holliensis A.Chev. can also be affected by vertebrate pests, such as birds, rodents, and deer. These pests can cause significant damage by chewing on the leaves, fruits, and stems of the plant.
Management: To prevent vertebrate pests, use physical barriers such as netting or fencing. Electric fences can also be used to deter large animals. Alternatively, organic repellents can be sprayed on the plant to discourage animals from feeding. It is essential to apply repellents regularly to maintain their effectiveness.
In conclusion, proper disease and pest management are essential for the healthy growth and yield of Capparis holliensis A.Chev. Regularly inspecting the plant, implementing appropriate control measures, and preventing infestations are key to effective disease and pest management.
