oxalis thrives in bright, indirect light, preferably in a location that is cool at night (60°F) and warm during the day (70°F). The foliage has the unique ability to close its leaves during levels of low light, whether at night or on cloudy days. This behavior serves as a defense mechanism against excessive light. If you notice this, consider relocating the plant to a shadier spot or provide protection from intense sunlight.
Ensure it's planted in well-drained potting mix within a container that has proper drainage. While this plant prefers to be somewhat "pot bound," it's important to avoid overwatering and ensure the soil remains consistently moist, but not wet. Water two to three times a month, allowing soil to dry out between waterings.
