Oxalis ramigera Sond. is a moderately shade-tolerant plant species. It thrives well in bright light, preferably indirect sunlight. Therefore, planting it in partially shaded areas with at least four to six hours of bright light per day is ideal. Full sunlight may cause the plant to wilt or bleached leaves. On the other hand, deeply shaded areas may result in leggy plants and less-frequent blooming.
Temperature Requirements
The plant species has a wide temperature tolerance range and can grow in almost all temperature zones. However, the ideal temperature range for Oxalis ramigera Sond. is between 10°C to 30°C. Extreme heat may cause the leaves to scorch, while cold temperatures may affect the plant's growth and cause the leaves to wither.
Soil Requirements
Oxalis ramigera Sond. grows best in well-drained soils, which are slightly acidic with a pH range of 5.5 to 6.5. The soil should be fertile, rich in organic matter, and able to retain moisture. Sandy loam soil is most suitable as it provides enough aeration and drainage that prevents waterlogging. Additionally, adding compost to the soil enhances the nutrient uptake and helps in maintaining soil moisture levels.
Cultivation methods
Oxalis ramigera Sond. is a perennial bulbous plant native to South Africa. It is quite resilient and easy to cultivate, and it would thrive in a variety of positions from full sun to partial shade. You can grow Oxalis ramigera in garden beds, borders or containers.
Prepare the planting bed by removing stones, weeds, and roots. Mix organic matter, such as compost or well-rotted manure, into the soil to improve drainage and nutrient retention. Plant the bulbs in autumn, with the top of the bulb just below the soil surface. Spacing should be at least 10 cm apart to promote good air circulation.
Watering needs
Oxalis ramigera Sond. likes moist soils but can tolerate short periods of dryness. Water regularly during the growing season, especially in full sun or warm positions when the soil is more likely to dry out. Avoid overwatering as this can cause the bulbs to rot. Use mulch to help retain moisture and suppress weeds.
Fertilization
Oxalis ramigera Sond. benefits from regular fertilization to promote healthy growth and flowering. A balanced granular fertilizer can be applied during the growing season, every four to six weeks. Reduce feeding when it starts to die back in the autumn.
Pruning
To promote and maintain bushy growth, you can pinch back leggy stems occasionally. It also helps to deadhead spent flowers regularly. Pruning is not generally necessary for the health of the plant, and too much pruning can reduce flowering.
Propagation of Oxalis Ramigera Sond.
Oxalis Ramigera Sond. is a bulbous plant that propagates using various methods such as seeds, bulbs, and cuttings.
Seed Propagation
The plant produces seeds after flowering. Collect the seeds when the pods have dried and turned brown. Sow the seeds in a well-draining soil mixture. Keep the soil moist and warm at all times. Germination should occur within two weeks.
Bulb Propagation
The bulb is the main storage organ for the plant, and it will reproduce by developing small bulblets. The bulblets can be separated from the main bulb and planted in well-draining soil. Cover the bulblets lightly with soil and keep them moist. They should start growing within two to three weeks.
Cutting Propagation
Cuttings of Oxalis Ramigera Sond. are easy to propagate. Take the cuttings during the growing season and ensure that they have a few leaves attached. Dip the bottom of the cutting in rooting hormone and plant it in well-draining soil. Keep the soil moist and warm until new growth appears. Within six to eight weeks, the cutting should have developed roots and new growth.
Disease and Pest Management for Oxalis ramigera Sond.
Oxalis ramigera Sond. is a beautiful ornamental plant that is relatively resistant to pests and diseases.
