Lithodoras originate from regions with light and rocky soils. While regular watering in dry periods is important while the plant is establishing , it’s better to allow mature plants to dry out between waterings. Lithodoras prefer well drained soils, of acidic pH. Avoid heavy clay soils with poor drainage. Low fertilizer requirements, do not over feed.
