Watering. Water thoroughly but infrequently. Allow soil to dry completely between waterings to prevent root rot. Reduce watering in winter when the plant is dormant.
Fertilizing. Feed with a balanced cactus fertilizer diluted to half strength every 4 to 6 weeks during the growing season (spring and summer). Avoid fertilizing in winter when the plant is dormant.
This cactus is fairly easy to care for but needs bright light and well-draining soil. Overwatering can cause root rot, so water sparingly and let the soil dry out between waterings. It grows quickly under good conditions and benefits from occasional feeding during the growing season.
