Cultivation and propagation: It is a summer-growing and easy cactus to grow. It makes great potted specimens.
Growth rate: Espostoa produces noticeable amounts of growth each year if kept well fed and watered throughout the warmest months, particularly if it has been acclimatized to accept full sun.
Soils: It likes very porous standard cactus mix soil with little organic matter (peat, humus).
Repotting: Repotting every 2-3 years. Needs lots and lots of space to grow, use large container filled with very porous compost. Use pot with good drainage.
Watering: Water the plants well and allow them to dry before watering again.
Sun exposure: Outside full sun, inside needs bright light, and some direct sun. During winter months, put them in a cool luminous place and encourage them to enter winter dormancy by withholding water over the winter as they will etiolate, or become thin, due to lower levels of light.
Hardiness: It is easy to grow and cold hardy as low as -12°C (or less).
