• Plant the edible purple oxalis in a pot of approximately 2 liters with high-quality potting soil. Ensure good drainage at the bottom using clay pebbles.
• Water generously at the base of the plant during planting.
• Place it in a shaded area for 3 to 4 days to allow it to acclimate.

- Soil type / Substrate:

It grows very well in any type of soil; however, it prefers a light, well-draining substrate rich in organic matter.

- Exposure / Light:

This small purple-leaved clover loves bright light. It is best to find a full sun location so it can grow properly. It tolerates shade but will produce fewer leaves.

- Temperature / Hardiness:

The little wild sorrel thrives when temperatures range from 15 to 25°C. Below this, it grows more slowly but does not suffer. This small herbaceous plant easily resists cold temperatures down to -10°C. Its USDA hardiness zone is 5.

- Watering / Irrigation:

Irrigation should be done at the base of the plant. It is necessary to water it twice a week in mid-summer if it is exposed to full sun. Otherwise, it does not require watering if grown in the ground. It is very hardy and highly resistant to water shortage and drought.

- Multiplication / Reproduction:

Oxalis corniculata reproduces mainly by clump division throughout the year. It can also be propagated by sowing its seeds.

- Pests / Diseases:

This variety is sometimes attacked by aphids or red spider mites in the spring. Over-watering can lead to powdery mildew on the foliage, a fungal disease that should be treated promptly.
