Watering. Water sparingly, allowing the soil to dry out completely between waterings. Reduce watering significantly in winter when the plant is dormant.
Fertilizing. Feed with a balanced cactus fertilizer during the growing season (spring and summer), about once a month. Avoid fertilizing in winter when the plant is dormant.
Espostoa lanata is a slow-growing cactus that prefers bright light and minimal watering. It is drought-tolerant and needs well-draining soil to prevent root rot. Avoid overwatering and provide good air circulation to keep it healthy.
