Becium grandiflorum var. decumbens is a perennial herb which is commonly found in the grasslands and rocky areas of southern Africa. The plant requires certain growth conditions to thrive, which include:
Light requirements
The plant prefers to grow in areas that receive full sunlight. In its natural habitat, it is commonly found in open grasslands and rocky areas that receive minimum to no shade. Lack of adequate sunlight can lead to stunted growth and reduced flowering in the plant.
Temperature requirements
Becium grandiflorum var. decumbens grows best in areas with a warm and temperate climate. The plant can tolerate a wide range of temperatures, from as low as 10° C in winter to as high as 35° C during summer. However, it is not frost-tolerant and can get damaged by low temperatures.
Soil requirements
The plant grows well in a well-drained soil that is rich in nutrients. It tolerates a wide range of soil types, including sandy, loamy, and clay soils, as long as they are well-draining. However, the plant does not tolerate waterlogged soils. Becium grandiflorum var. decumbens does not require high amounts of fertilizers, but adding organic matter in the soil can help improve growth and flowering.
Cultivation Methods
Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald prefers warm and sunny locations with well-draining soil. It can be grown in pots or directly in the ground, but ample space is needed as it can spread up to 1 meter in diameter. In areas with mild winters, it can be grown year-round outdoors. In colder climates, it is recommended to grow it indoors or in a greenhouse during winter.
Watering Needs
Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald prefers moderate watering. It is important to avoid overwatering as it can lead to root rot. The soil should be allowed to dry out slightly between watering to prevent waterlogging. However, it is crucial to keep the soil evenly moist during the flowering period to avoid stress on the plant.
Fertilization
It is recommended to fertilize Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald with a balanced fertilizer every two weeks during the growing season. Avoid fertilizing during the winter period. Over-fertilization should also be avoided as it can cause damage to the plant.
Pruning
Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald requires minimal pruning. However, it is recommended to trim back the plant after the flowering period to encourage bushier growth. Pinching off the tips of the branches during the growing season can also help to prevent the plant from becoming too leggy. Pruning should also be done to remove damaged or diseased branches immediately to prevent the spread of infection to the rest of the plant.
Propagation of Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald
Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald can be propagated through seeds, cuttings, and division.
Seeds
Seeds of Becium grandiflorum (Lam.) Pic.Serm. var. decumbens (Gürke) Sebald can be sown directly into the soil. The best time to sow seeds is in spring or early summer when the soil is warm. The seeds should be sown at a depth of 3 mm and spaced about 30 cm apart. The soil should be kept moist until the seedlings emerge.
Cuttings
Cuttings can be taken in late spring or early summer. The cuttings should be about 10 cm long and taken from the tip of the stem. The lower leaves should be removed, and the cutting should be dipped in rooting hormone. The cutting should be planted in a well-draining rooting medium and kept moist until roots develop.
Division
The plant can be divided in early spring. The clump should be carefully dug up, and the root system separated into individual sections. Each section should have several stems and a healthy root system. The sections should be replanted in a well-draining soil and watered thoroughly.
Disease Management
One of the most common diseases that affect Becium grandiflorum var. decumbens is fungal leaf spots. These are circular spots that appear on the leaves and can lead to the defoliation of the plant. The best way to manage this disease is to keep the leaves dry by watering the plant early in the morning and providing adequate spacing between plants to promote good air circulation. If the disease persists, it is advisable to use a fungicide that is labeled for use on the plant.
Another common disease that can affect Becium grandiflorum var. decumbens is powdery mildew. This is a fungal disease that appears as a white powdery substance on the surfaces of leaves, stems, and flowers. To manage this disease, it is important to keep the plants well-spaced and to prune any plants that are heavily infected. Applying a fungicide that is labeled for use on the plant may also be necessary.
Pest Management
One of the common pests that attack Becium grandiflorum var. decumbens is the whitefly. These are tiny white insects that suck sap from the leaves of the plant, leading to yellowing and stunted growth. To manage whiteflies, it is important to keep the plants healthy by providing adequate water, fertilization, and pruning. Encourage natural predators such as ladybugs and lacewings to control the population. If the population is too high, you can apply a insecticide that is labeled for use on the plant.
Another pest that can attack Becium grandiflorum var. decumbens is spider mites. These are tiny pests that also suck sap from the plant, leading to stunted growth and discoloration of the leaves. To manage spider mites, it is important to keep the leaves of the plant clean by regularly spraying with water. Encouraging natural predators and applying an insecticide that is labeled for use on the plant can also be effective.
