🌱 How to Care for False Shamrock to Prevent Mealybugs?

💧 How to Water

Water every 10–14 days, only when the top 1–2 inches of soil are dry. Oxalis grows from corms that are very susceptible to rot in soggy conditions. During dormancy, withhold water completely and resume when new shoots emerge.

☀️ Lighting

Provide bright indirect light — an east-facing or curtain-filtered south/west window is ideal. Direct harsh sun can scorch leaves and trigger premature dormancy. Too little light causes leggy stems and dull leaf color. The leaves will naturally open toward the light source.

🪴 Ideal Soil

Use a well-draining potting mix enriched with perlite or coarse sand. Ensure the pot has drainage holes. A slightly acidic to neutral pH (6.0–7.0) suits this plant best. Heavy or compact soils that retain moisture will quickly cause corm rot.
