🌱 How to Care for Common mallow to Prevent Whiteflies?

💧 How to Water

Water when the top 2–3 cm of soil has dried out, approximately every 7 days during the growing season. The plant is drought-tolerant due to its strong taproot but performs best with consistent moisture during flowering. Significantly reduce watering during winter dormancy. Avoid standing water, which can cause root rot.

☀️ Lighting

Place in full sun (6–8 hours of direct light per day) for best flowering and growth. Tolerates partial shade but will flower less profusely. Not suitable as an indoor plant as it requires outdoor conditions and open ground.

🪴 Ideal Soil

Prefers loose, loamy, and well-drained soil enriched with compost. Tolerates most soil types—sand, clay, and silt—but thrives less in dense, waterlogged soil. Optimal pH: 6.0–8.0. Consider improving with well-rotted manure before sowing.
