🌱 How to Care for Siskiyou Lewisia to Prevent Aphids?

💧 How to Water

Water every 7–10 days during the growing season, allowing the soil to dry out completely between waterings. In winter, reduce to once every 3–4 weeks. Never allow moisture to sit at the crown — this plant is highly prone to crown rot and root rot. Always water at the base, never overhead, and use morning watering to allow any surface moisture to evaporate.

☀️ Lighting

Prefers full sun to light partial shade with a minimum of 4–6 hours of direct sunlight daily. In hot climates, protect from intense midday sun to prevent leaf scorch. Indoors, place near an east or west-facing window for bright indirect light.

🪴 Ideal Soil

Requires sharply draining, gritty soil — ideally a cactus/succulent mix with added perlite and coarse sand. Soil pH between 6.0 and 7.0. Never use heavy, moisture-retentive soil. In nature, this plant grows on near-vertical rocky cliff faces with minimal soil.
