🌱 How to Care for Candy Cane Sorrel to Prevent Anthracnose?

💧 How to Water

Water every 7 days during the growing season, allowing the top inch of soil to dry out between waterings. During summer dormancy, stop watering almost completely. Overwatering is the primary cause of bulb rot—always use well-draining soil and pots with drainage holes.

☀️ Lighting

Provide full sun to partial shade (at least 4–6 hours of direct sun daily). The flowers only open fully in bright light—insufficient light leads to poor flowering and leggy stems. Avoid harsh afternoon sun in very hot climates.

🪴 Ideal Soil

Use a well-draining mix such as sandy loam or a standard potting mix amended with perlite or coarse sand. Slightly acidic to neutral pH (6.0–7.0) is ideal. Good drainage is critical to prevent bulb rot.
