🌱 How to Care for Cornish Lily to Prevent Spider Mites?

💧 How to Water

Water about once a week while leaves and flower stems are actively growing, letting the top of the soil dry between waterings. Stop watering almost entirely once the foliage yellows and dies back for summer dormancy, resuming only when new growth appears.

☀️ Lighting

Give it a warm spot in full sun, such as a bed against a sunny, sheltered wall, or at least several hours of direct light a day; too much shade weakens flowering.

🪴 Ideal Soil

Plant in gritty, sharply-draining soil -- equal parts loam-based compost, peat-free multipurpose compost and coarse sand or grit work well -- with the bulb's neck sitting just proud of the soil surface to prevent rot.
