Temperature Requirements
Becium obovatum subsp. cordatum grows in a range of temperatures from mild to warm. It is well-suited to Mediterranean climates where the summers are hot and dry while the winters are mild and wet. However, it can also tolerate cooler temperatures as long as there is no frost or prolonged periods of freezing temperatures.
Soil Requirements
Becium obovatum subsp. cordatum prefers well-draining soils that are rich in organic matter. It can tolerate a range of soil types including sandy, loamy, and clay soils. However, it is sensitive to water-logging and requires adequate drainage to prevent root rot.
Cultivation Methods
Becium obovatum subsp. cordatum is a plant that is relatively easy to cultivate. It thrives in full sunlight, although it can also tolerate partial shade. The plant prefers well-draining soils, such as sandy or loamy soils, with a pH between 5.5 and 7.5. It is not tolerant of waterlogged soils, so ensure adequate drainage if grown in pots or containers. Becium obovatum subsp. cordatum can be propagated through cuttings or seeds, with cuttings being the faster method of propagation.
Watering Needs
Watering needs of Becium obovatum subsp. cordatum is moderate. This plant prefers soil that is moist but not waterlogged. During the growing season, water the plant once or twice a week, depending on the soil and environmental conditions. Avoid watering the plant too often, as it can lead to root rot.
Fertilization
Becium obovatum subsp. cordatum is a low-maintenance plant that does not require frequent fertilization. Applying general-purpose fertilizer once in six months, during the growing season, is sufficient. Alternatively, you can amend the soil with organic matter, such as compost or well-rotted manure, before planting to provide the necessary nutrients.
Pruning
Pruning of Becium obovatum subsp. cordatum is generally light. Pinching back the tips of the plants and removing dead or damaged stems encourages bushier growth. Regular pruning helps to keep the plant looking neat and tidy, promotes better air circulation, and helps prevent the spread of diseases. Pruning should be done at the beginning of the growing season or after the blooming season.
Propagation of Becium obovatum subsp. cordatum
Becium obovatum subsp. cordatum, commonly known as heart-leaved becium, is a semi-hardy perennial plant that is native to South Africa. The plant has attractive small, oval leaves with a slight sheen on the surface. The plant has small, pink to purple flowers that bloom in clusters during the summer months.
Propagation methods of Becium obovatum subsp. cordatum
Becium obovatum subsp. cordatum is propagated through various methods, including:
Seed propagation
The easiest and most common method of propagation for Becium obovatum subsp. cordatum is through seed propagation. The seeds should be sown in a well-draining soil mix and covered lightly with soil. They should be kept moist and placed in a warm, well-lit area. Germination of the seeds generally occurs within two to three weeks.
Softwood cuttings
Softwood cuttings are another method of propagation that works well for Becium obovatum subsp. cordatum. The cuttings should be taken during the spring or early summer months when the plant is actively growing. They should be about 10 cm in length and taken from the tips of the plant. The cuttings should be dipped in rooting hormone and placed in a well-draining potting mix. They should be kept moist and placed in a warm, well-lit area. Rooting of the cuttings generally occurs within four to six weeks.
Division
Division is also a viable method of propagation for Becium obovatum subsp. cordatum. The plant can be divided during the spring or early summer months when it is actively growing. The clump of the plant should be lifted from the ground, and the roots gently teased apart. The divided plants should be replanted in well-draining soil and kept moist until they are established.
Disease Management
Becium obovatum subsp. cordatum may be susceptible to several fungal and bacterial diseases such as leaf spot, powdery mildew, and bacterial blight. These diseases may lead to defoliation and weak plant growth.
To manage these diseases, it is advisable to remove and dispose of the infected plant parts. It is also essential to maintain proper plant hygiene by preventing overcrowding and ensuring good air circulation. Additionally, preventive fungicidal and bactericidal sprays may be used to protect and minimize disease spread.
Pest Management
Becium obovatum subsp. cordatum is often vulnerable to pest infestations such as spider mites, scale insects, and mealybugs. These pests usually suck out the sap of the plant, leading to yellowing, wilting, and eventual death of the plant.
To control these pests, it is important to regularly inspect the plants for signs of infestation. The use of natural predators like ladybugs or introducing insecticidal soaps and neem oil can be effective in managing pests. It is also essential to avoid over-fertilizing the plants as this may attract more pests.
