Oxalis sp. (Shamrock)

Oxalis like cool air and moist soil while they are growing. Bright indirect light is best, but they will grow in lower light levels. Fertilize weekly while they are growing with a balanced fertilizer. Shamrocks are bulbs, and they require a dormant period every once in a while. Restrict all watering. As with any bulb, let the leaves die back naturally. Do not remove any leaves until they are brown. Let the bulbs stay dormant for 3 to 4 weeks, then water and fertilize. In most indoor-grown shamrocks, this dormant period occurs 2 to 3 times a year.
