Becium grandiflorum (Lam.) Pic.Serm. var. obovatum (E.Mey. ex Benth.) Sebald thrives in full sunlight to partial shade. In regions with intense heat, providing partial shade is ideal to prevent the plant from wilting due to water loss.
Temperature Requirements
The ideal temperature for the growth of Becium grandiflorum (Lam.) Pic.Serm. var. obovatum (E.Mey. ex Benth.) Sebald ranges between 25 and 35 degrees Celsius. It is a warm-season plant that can tolerate high temperatures, but it cannot flourish in extreme cold.
Soil Requirements
Becium grandiflorum (Lam.) Pic.Serm. var. obovatum (E.Mey. ex Benth.) Sebald prefers soils that are well-drained and fertile. The plant can grow in a wide range of soils, including sandy loams, clay loams, and loamy soils. The pH range of the soil should be between 5.5 and 7.5, which is slightly acidic to neutral. The plant can tolerate salty soils, but it will not survive in water-logged conditions.
Cultivation Methods
Becium grandiflorum (Lam.) Pic. Serm. var. obovatum (E.Mey. ex Benth.) Sebald, commonly known as Wild Sage, is a South African shrub that thrives in dry and rocky areas. To cultivate this plant, provide it with well-draining soils that are rich in organic matter. Wild Sage requires full sun exposure for at least six hours each day to grow correctly.Watering Needs
Wild Sage is very tolerant of drought, and excessive watering can lead to root rot and other fungal diseases. Water this plant sparingly and make sure that the soil is completely dry before the next watering. During the growing season, it is recommended to water the plant once every two to three weeks.Fertilization
Fertilization is not a requirement for Wild Sage, but it can be beneficial for the growth of the plant. Use a low nitrogen fertilizer with a balanced NPK ratio that contains equal amounts of phosphorous (P) and potassium (K). Apply it once every six months or as required. Over-fertilizing can lead to nutrient buildup in the soil and cause harm to the plant.Pruning
Wild Sage does not require extensive pruning. Prune the plant to remove any dead or damaged branches and to maintain its shape. Pruning also helps to promote vigorous growth and abundant flowering. It is recommended to prune Wild Sage after the blooming season has ended. Sterilize pruning tools before and after use to prevent the spread of diseases.Propagation of Becium grandiflorum var. obovatum
Becium grandiflorum var. obovatum, commonly known as Wild Rosemary, is a shrubby plant that belongs to the Lamiaceae family. It is a common plant in southern African regions, and its propagation can be achieved through different methods.
Seed propagation
One of the primary forms of propagating Becium grandiflorum var. obovatum is through seeds. The seedlings take roughly 3 to 4 weeks to germinate, and they can be planted in a nursery setup first before being transplanted into their permanent position later. The optimum germination temperature is around 20 to 30 °C.
The soil should be well-draining and fertile, with a pH range of 5.5-7.2. It is essential to keep the soil moist during the germination period, and seeds should be sown at a depth of around 3mm in furrows. After germination, the seedlings should be thinned out and transplanted into separate putting bags or trays.
Cuttings propagation
Becium grandiflorum var. obovatum can also be propagated through cuttings. This method is useful in scenarios where mature plants have been established or for when the seedlings are unavailable. The cuttings can be taken from the current season's growth, measuring about 7-10 cm long, and planted into moist potting soil placed in a tray.
The cuttings should be placed at a depth of about 2-3 cm and kept in a shaded area with adequate humidity. The tray should be covered in a transparent plastic bag to help keep the moisture level consistent. After a few weeks, the roots should start to develop, and the cuttings can be transferred to small pots with well-draining soil.
Division propagation
Another viable method of propagating Becium grandiflorum var. obovatum is through division. It involves splitting the roots of mature plants to establish new plants. The process is best done in the spring as it is the best time for the plants to recover from the cuttings.
Be careful during this process to avoid damage to the roots. For the best results, dig up the whole root ball and gently pry apart the plant sections. Once you have obtained new plant sections with roots intact, plant them free in separate pots or on the ground, spacing out at least half a meter apart for proper growth and development.
Disease Management for Becium grandiflorum var. obovatum
Becium grandiflorum var. obovatum is a hardy plant with a good resistance to most diseases. However, some diseases can still affect the plant, particularly if grown in poorly drained soil or excessive moisture conditions.
Fungal diseases like powdery mildew, gray mold, and downy mildew can affect the plant in conditions of high humidity. To manage these diseases, growers can promote good air circulation around the plant by spacing them appropriately. Growers can spray the plant with a fungicide or a mixture of baking soda and water mixed with plant oil.
Bacterial diseases can also affect the plant, causing wilting, yellowing and necrosis of plant tissues. To manage bacterial diseases, growers should practice good sanitation in the growing area by removing plant debris and infected plant material promptly and treating the plant with a bactericide.
Pest Management for Becium grandiflorum var. obovatum
Becium grandiflorum var. obovatum is relatively resistant to pests. However, certain pests can still pose a threat to the plant, particularly if grown in warm and dry conditions.
Squash bugs, aphids, and spider mites can attack the plant, causing stunted growth, yellowing leaves and even plant death. To manage pest problems, growers should practice good sanitation by removing plant debris and infected tissue promptly and treating the plant with pesticides. Neem oil and insecticidal soap are organic options for managing the pests.
Growers should also practice crop rotation and companion planting to help protect the plant from pests. Planting companion species like marigold and garlic can deter pests, while rotating the growing area can help break the pest cycle.
