Temperature Requirements
Boerhavia erecta L. is highly adaptable and can grow in a wide range of temperatures. It can tolerate both hot and cold weather conditions. The plant can withstand temperature ranges between 15°C to 45°C. However, an optimal temperature range of 20°C to 30°C is ideal for its growth and development.
Soil Requirements
Boerhavia erecta L. grows well in various soil types ranging from sandy, loamy to clay soils, but it prefers well-drained soils with good aeration. It can grow in both acidic and alkaline soils but prefers a slightly acidic to neutral soil pH range between 6.0 to 7.5. The plant can also tolerate saline soils but not waterlogged conditions.
Boerhavia erecta L. requires a soil rich in nutrients, especially nitrogen, phosphorus, and potassium. Organic matter-rich soils are ideal for the growth of this plant species. Adequate soil fertility levels are vital in promoting plant growth, flower bud formation, and fruit set.
Cultivation methods
Boerhavia erecta L. is a hardy, drought-resistant plant that thrives in warm temperatures. It is best grown in well-draining soil that is rich in organic matter. The plant can be grown from seeds or cuttings, which should be planted in a warm and sunny location. It is important to space the plants about 24 inches apart to allow the roots to spread easily.
Watering needs
Boerhavia erecta L. requires moderate watering. The plant does well in dry conditions, but it is crucial to keep the soil moist during the first few weeks after planting. Once established, the plant can handle occasional dry spells. It is important to water the plant deeply and infrequently to encourage deep root growth.
Fertilization
Boerhavia erecta L. benefits from regular fertilization. A slow-release fertilizer can be applied to the soil during planting or after the plant has become established. It is also recommended to supplement the soil with organic matter such as compost or manure. However, avoid over-fertilization, which can lead to excessive foliage growth and reduced flower production.
Pruning
Boerhavia erecta L. does not require extensive pruning, but it can benefit from occasional maintenance to promote healthy growth. Deadheading can encourage the plant to produce more flowers, and pruning can be used to shape the plant and remove damaged or diseased foliage. However, avoid excessive pruning, which can damage the plant and reduce flower production.
Propagation of Boerhavia erecta L.
Boerhavia erecta L., commonly known as erect spiderling or tar vine, is a flowering plant that belongs to the four o'clock family. Propagation of Boerhavia erecta L. is mainly carried out through seeds and cuttings. The plant can be propagated throughout the year, but the best time to propagate is during the rainy season.
Propagation through seeds
The seeds of Boerhavia erecta L. can be directly sown in the field or in pots filled with well-draining soil. Before sowing, the seeds should be soaked in water for 24 hours. They should be sown 2-3 cm deep in the soil and spaced at least 30 cm apart. The seedlings emerge within 10-14 days. The young seedlings should be watered regularly until they establish.
Propagation through cuttings
The cuttings of Boerhavia erecta L. can be taken during the growing season. The cuttings should be 10-15 cm long and taken from healthy plants. They should be dipped in rooting hormone powder and planted in pots or in the ground filled with well-draining soil. The cuttings should be watered regularly until they firmly establish.
In conclusion, Boerhavia erecta L. can be propagated through seeds and cuttings. The best time to propagate is during the rainy season. The young seedlings and cuttings should be watered regularly until they establish.
