Light requirements
The plant Capparis lilacina Gilg usually requires bright and direct sunlight for optimal growth. In its natural habitat, it can be found growing in open areas, sunny slopes, and rocky terrain. Therefore, to ensure healthy growth, it is advisable to place it in a spot where it receives at least six hours of direct sunlight per day.
Temperature requirements
Capparis lilacina Gilg is well adapted to grow in hot and dry conditions. It grows best in temperatures ranging from 25°C to 35°C. However, it can tolerate slightly lower temperatures during the winter season. Extreme cold temperatures can cause damage to the plant.
Soil requirements
The plant prefers well-drained and nutrient-rich soil. It grows best in sandy or loamy soil that is slightly acidic to neutral (pH 6.0 to 7.5). Capparis lilacina Gilg is a drought-tolerant plant, and it can survive in moderately saline soils. However, it is best to avoid waterlogged soils as they can lead to root rot.
Cultivation
Capparis lilacina Gilg, commonly known as the Kenyan caper plant, is a small shrub that is native to the dry regions of East Africa. It can be grown both indoors and outdoors. For outdoor cultivation, it requires a well-drained soil with plenty of sunshine. It can also be grown in a container in a warm greenhouse or sunny window ledge.
Watering Needs
Capparis lilacina Gilg prefers a dry environment and can tolerate short periods of drought. It is essential to avoid overwatering the plant as it can lead to root rot. Water the plant only when the soil is completely dry. For container-grown plants, ensure that there are drainage holes to avoid waterlogging.
Fertilization
During the growing season, feed Capparis lilacina Gilg with a balanced fertilizer once per month. Avoid nitrogen-rich fertilizers as they may encourage leafy growth at the expense of flower production. Consider using a fertilizer that is specifically formulated for flowering plants to promote abundant blooms.
Pruning
Prune Capparis lilacina Gilg after flowering to help maintain its shape and size. It tends to produce long, sprawling branches that can be cut back to promote bushier growth. Cut back any dead, diseased, or damaged branches as soon as they are spotted. Avoid heavy pruning as it may reduce the number of flowers produced in the following season.
Propagation of Capparis lilacina Gilg
Capparis lilacina Gilg, commonly known as African Caper, is propagated by seed, stem cutting, or layering. The following are the propagation methods:
Seed Propagation
Seeds of Capparis lilacina are collected and sown in a well-draining seedbed during the spring season. The seedlings will begin to emerge after a few weeks. Once the seedlings reach a height of 10 cm, they can be transplanted into individual pots filled with a well-draining potting mix. The pots should be kept in a warm and protected place.
Stem Cutting Propagation
Stem cuttings of Capparis lilacina can be taken from the current year's growth during the early spring or fall. The cuttings should be about 15-20 cm long, with a couple of leaves on the top. Remove the bottom leaves and dip the cut end in rooting hormone. Plant the cuttings in a well-draining rooting medium and keep them in a warm, humid place. The cuttings will begin to root within a few weeks.
Layering Propagation
Layering is another method of propagating Capparis lilacina. During the spring season, a low branch of the mother plant is selected, and a portion of the stem is buried in the soil, leaving the top portion exposed. The buried stem should be wounded and treated with rooting hormone before covering with soil. The stem will begin to grow roots in a few weeks. Once the roots have developed, the new plant can be separated from the mother plant and transplanted into a pot or a new location.
Disease Management
Capparis lilacina Gilg is prone to various fungal and bacterial diseases that can affect the plant's growth and ultimately reduce its productivity. Below are some common diseases and ways to manage them.
Anthracnose
Anthracnose is a fungal disease that affects the leaves and fruit of the Capparis lilacina Gilg plant. It causes circular lesions on leaves, which turn brown and dry out. In severe cases, it can affect the fruit, causing it to rot and drop off the plant. To manage anthracnose, ensure the plant has good air circulation, avoid overhead watering, and remove infected plant parts.
Powdery Mildew
Powdery mildew is a fungal disease that affects the leaves of the Capparis lilacina Gilg plant. It appears as a whitish powdery growth on the leaves, which can distort and stunt their growth. To manage powdery mildew, ensure the plant has good air circulation, avoid overhead watering, and apply fungicides as needed.
Bacterial Leaf Spot
Bacterial leaf spot is a bacterial disease that affects the leaves of the Capparis lilacina Gilg plant. It causes black or brown spots on the leaves, which can enlarge and join together causing the leaves to fall off. To manage bacterial leaf spot, remove infected leaves, ensure the plant has good air circulation, and avoid overhead watering.
Pest Management
Capparis lilacina Gilg is also prone to insect pest infestations, which can cause significant damage to the plant. Below are some common pests and ways to manage them.
Scale Insects
Scale insects are common pests that can infest Capparis lilacina Gilg plants. They appear as small, flat, oval-shaped pests that attach themselves to the stem or leaves of the plant. They feed on the plant's sap, causing yellowing and stunted growth. To manage scale insects, prune and dispose of infected plant parts, spray insecticides, and introduce biological control agents such as ladybugs.
Aphids
Aphids are small, pear-shaped insects that feed on the sap of Capparis lilacina Gilg plants. They cause curling and yellowing of leaves, stunted growth, and can transmit diseases. To manage aphids, prune and dispose of infected plant parts, spray insecticides, and introduce biological control agents such as ladybugs.
Leaf Miners
Leaf miners are small insects that feed on the leaves of Capparis lilacina Gilg plants. They create tunnels within the leaves, which can cause defoliation and damage to the plant. To manage leaf miners, prune and dispose of infected plant parts, use sticky traps to capture adults, and apply insecticides as needed.
