🌱 How to Care for Saffron crocus to Prevent Thrips?

💧 How to Water

Do not water during summer dormancy (late June to September). In autumn and winter, water only if the soil is dry and no rain is forecast. In spring, maintain light and regular watering (about 30 mm/week, on alternate days) until the foliage withers. Never allow the soil to become waterlogged—excess water is the primary cause of corm rot.

☀️ Lighting

Requires full sun—at least 6 to 8 hours of direct light per day—to bloom well. Shaded locations drastically reduce flowering and stigma production.

🪴 Ideal Soil

Use sandy, light, and very well-drained soil with a slightly alkaline pH (6.0 to 8.0). Avoid clay-heavy or waterlogged soils, and avoid replanting in soil where other plants from the Iridaceae family have previously grown to reduce the risk of fungal diseases.
