How to Grow and Care
These plants need bright indirect light to grow well and produce flowers. They can often bloom all winter if kept in a sunny spot. Keep the soil barely moist but never soggy. Allow the top 2 inches (5 cm) of the soil to dry out before watering. It is best to water your Oxalis from the bottom so that the thin, fragile stems of the plant don't get waterlogged and the soil stays loose. Oxalis plants grow best in cool temperatures between 60 to 70 ºF (15 to 21 ºC) during the day and 55 to 65 ºF (13 to 18 ºC) at night. The soil should be loose and sandy rather than rich and organic. Feed your plant monthly when it is actively growing with a basic houseplant food at 1/2 the recommended strength. Never feed an Oxalis when it is dormant, and the bulbs are resting.
To propagate Oxalis, simply split the plant into smaller plants and place them in their own pots. Keep it out of direct sunlight until new shoots appear.
