Care & Maintenance

Often referred to as Wood Sorrels, Oxalis are also known as False Shamrocks and a plethora of other common names. Of the Oxalis species in cultivation, Oxalis triangularis is the one most commonly cultivated as a houseplant.

Oxalis are not only excellent houseplants because they come in a range of colors and sizes, but also because they are so prolific. Many will go through a dormant phase in the wintertime if kept as a houseplant. A significant portion of the play may die and go into dormancy if not receiving enough light. Give a dose of fertilizer and more light and it’ll grow back.

Sunlight: Thrives in bright indirect to bright direct light. Can handle a few hours of direct sun.

Water: Water every 1-2 weeks, allowing the soil to dry out halfway down between waterings. Expect to water more often in brighter light and less often in lower light.

Common Problems: It is generally a very easygoing plant. Should it get spider mites, treat the plant as soon as they appear with weekly sprays of horticultural (Neem) oil and regular wipe-downs of the plant.
