How much water should I give my false shamrock (Oxalis) houseplant?


Wet soil is a quick way to kill a false shamrock plant. It must have fast-draining soil, be in a pot with a drain hole and be watered with attention. Water thoroughly, making the potting mixture moist and checking back after 15 minutes to remove any water sitting in the plant's run-off dish. When the plant is in active growth, keep the soil barely moist and allow the soil to just dry between waterings. After flowering, if the plant begins to die-back, taper watering and then keep the soil dry during the period of dormancy.

Humidity above 50% when in active growth will support a healthy plant with attractive leaves. Keep your plant on a tray of wet pebbles or moss. Employing a simple hygrometer near the plant will help you monitor whether the air moisture is staying in the targeted range.
