false shamrock

False shamrock plants (Oxalis triangularis) require regular, consistent watering. Water the soil until it is evenly moist but not soggy; it should be moist enough to hold together when lightly squeezed. In spring and summer, water once a week, allowing the top 1 inch of soil to dry out in between waterings. In fall and winter, reduce the frequency of watering to once every 2 weeks, also allowing the top 1 inch of soil to dry out in between waterings. False shamrock plants like high humidity so spraying them with water from a mister, especially in very dry conditions, can be beneficial.

Oxalis triangularis (false shamrock) does best in a sunny location. Allow it to receive at least 6 to 8 hours of sunlight per day for maximum growth and flowering. If placed in a less sunny area, the leaves and the flowering will be reduced but the plant will still live.

False shamrock is a low-maintenance plant, and does not require frequent pruning for optimal growth. To promote healthy foliage, the plant should be lightly pruned in late spring or early summer, as soon as flowering is finished. Using sharp gardening shears, deadhead any spent bloom stalks and trim back any overgrown stems. Pruning should be done incrementally, removing no more than 1/3 of the plant's growth at 1 time. It is not necessary to prune the plant regularly; instead, prune only when the plant appears to be overgrown.
