Light Requirements:
Oxalis eckloniana C.Presl var. sonderi T.M.Salter requires bright, indirect light to thrive. Direct sunlight can scorch the leaves, whilst insufficient light can cause the foliage to become spindly and weak. Therefore, placing the plant near a south or west-facing window is ideal.
Temperature Requirements:
The ideal temperature range for Oxalis eckloniana C.Presl var. sonderi T.M.Salter is between 60-80°F (16-27°C). Lower temperatures can cause the plant to become dormant and cease growing, whilst higher temperatures can cause foliage damage and dehydration. It is important to keep the plant away from any drafts or air conditioning/ heating vents that can cause temperature fluctuations.
Soil Requirements:
Oxalis eckloniana C.Presl var. sonderi T.M.Salter requires well-draining soil that is rich in organic matter. A mixture of peat moss, perlite, and coarse sand is ideal for this plant. The soil pH should be slightly acidic, around 5.5-6.5. It is important to avoid letting the plant sit in water as this can lead to root rot.
Cultivation
Oxalis eckloniana C.Presl var. sonderi T.M.Salter is best grown in a well-draining potting mix with a slightly acidic pH. It is a low maintenance plant that can be grown both indoors and outdoors in a suitable climate. The ideal temperature for growth is between 60-75°F (15-24°C) and it requires partial shade to full sun exposure.
Watering Needs
It is important to keep the soil moist but not waterlogged. Water the plant when the top inch of soil feels dry. Avoid letting the soil dry out completely as this can cause stress to the plant. During the winter months, reduce watering frequency to prevent waterlogging and root rot.
Fertilization
Feed the plant every two weeks during the growing season with a balanced fertilizer. Use a low-nitrogen, high-potassium fertilizer to promote blooming. Avoid overfertilizing as this can cause damage to the plant.
Pruning
Oxalis eckloniana C.Presl var. sonderi T.M.Salter does not require regular pruning, but deadheading spent blooms can encourage new growth and prolong blooming. Prune back the plant in early spring to promote bushier growth and remove any dead or damaged foliage.
Propagation of Oxalis eckloniana C.Presl var. sonderi T.M.Salter
Oxalis eckloniana C.Presl var. sonderi T.M.Salter, commonly known as the Pink Oxalis or Sonder's Wood Sorrel, is a beautiful ornamental plant that belongs to the Oxalidaceae family. The plant is native to South Africa and is popular for its pink flowers and attractive foliage.

Propagation by Seeds
Propagation of Oxalis eckloniana C.Presl var. sonderi T.M.Salter using seeds is relatively easy. Collect seeds from mature and healthy plants during the summer months. Sow the seeds in a potting mix that is well-drained and moist. Cover the container with a plastic wrap to conserve moisture and place it in a warm area with indirect sunlight.

Propagation by Cuttings
Propagation of Oxalis eckloniana C.Presl var. sonderi T.M.Salter can also be done through stem cuttings. Take a cutting of about 4-6 inches from a mature plant, making sure it has a few leaves and a node. Remove the lower leaves and dip the cut end in rooting hormone. Insert the cutting into a well-draining potting mix and water it until the soil becomes moist. Cover the pot with a plastic wrap to retain moisture and place it in a shaded area. After a few weeks, the cutting will develop roots, and it can be transplanted to an individual container.
Propagation by Bulbs
Propagation of Oxalis eckloniana C.Presl var. sonderi T.M.Salter can also be carried out by dividing the bulbs. Carefully dig up the bulbs during the dormant season and separate the smaller bulbs from the larger ones. Replant the bulbs in a well-draining potting mix, ensuring they are not crowded, and water them well. Place the potted plants in a shaded area until they start to grow, after which they can be placed in a sunny location.
