Light Requirements
The plant Oxalis adspersa Eckl. & Zeyh. prefers to grow in bright light conditions. It can tolerate partial shade but too much shade can result in poor growth and fewer flowers. It is best to grow the plant in a spot that receives bright but indirect light.
Temperature Requirements
For the best growth of Oxalis adspersa Eckl. & Zeyh., the temperature should be between 16°C and 21°C. Temperatures below 10°C can be harmful to the plant, and it cannot tolerate frost. During the winter, it is important to maintain a consistent temperature to avoid stress on the plant.
Soil Requirements
The plant prefers well-drained soil with a pH level of 5.5 to 6.5. It cannot tolerate waterlogged soil, so it is essential to provide adequate drainage. Sandy loam or loamy soil with good organic matter is ideal for the plant's growth.
It is important to avoid using heavy clay, as it can restrict the plant's growth by not allowing adequate root development. The soil should also be rich in nutrients. Incorporating organic compost or fertilizers can provide essential nutrients for growth.
Cultivation
Oxalis adspersa Eckl. & Zeyh., commonly known as pink oxalis, is a perennial plant species that is native to South Africa. It prefers well-drained, sandy soils, although it can grow in other soil types. The plant does well in both full sun and partial shade. Pink oxalis grows from a bulb that needs to be planted in autumn for the best results. The bulbs should be planted about 10cm deep and 10cm apart from each other.
Watering Needs
During the growing season, which is from late winter to early autumn, pink oxalis should be watered regularly. However, care should be taken not to overwater the plant as it can cause bulb rot. The soil should be kept slightly moist, and the plant should be watered at the base to avoid getting water on the leaves.
Fertilization
Pink oxalis does not require much fertilization. However, during the growing season, a light application of a balanced fertilizer can be beneficial. The fertilizer should be applied according to the manufacturer's instructions. Alternatively, well-rotted compost can be added to the soil to improve its fertility.
Pruning
Pink oxalis does not require much pruning. However, dead or damaged leaves can be removed periodically to maintain the plant's appearance. After the plant has finished flowering, the spent flowers and flower stems should be removed. This can encourage the growth of new flowers and prevent the plant from using up its energy on producing seeds.
