🌱 How to Care for Silver Squill to Prevent Leaf Spot?

💧 How to Water

Water every 2–3 weeks during the growing season, allowing the top inch (and ideally more) of soil to dry out completely before watering again. In winter, reduce to once per month or less. Never let the bulbs sit in soggy soil, as this quickly leads to rot.

☀️ Lighting

Place in bright, indirect light — a spot near an east- or west-facing window is ideal. It tolerates a few hours of direct morning sun but should be shielded from harsh afternoon sun. Avoid deep shade, which causes leggy, pale growth.

🪴 Ideal Soil

Use a well-draining mix such as a cactus/succulent potting blend or standard potting soil amended with perlite or coarse sand. A slightly acidic to neutral pH of 6.0–8.0 is acceptable. Good drainage is critical to prevent bulb and root rot.
