How to Grow and Care

Eulychnia is not common in cultivation, and only collectors with a specific interest in the genus seem to grow them. It requires full sun or light shade to keep the plant compact with strong, colored spines. It tends to bronze in intense light, which encourages flowering and heavy spine production. A light shadow may be useful on the hottest summer days.

These cacti require light but regular watering in summer. Let the soil dry between waterings. Keep the soil dry in winter.

Eulychnias need to be kept in a cool place during winter rest. They are resistant to light frost if kept on the dry side before and during cold weather. Eulychnias are hardy to 28 °F (-2 °C) in short periods.

Eulychnia likes very coarse, mineral cactus soil mix but can become too elongated if the soil is too rich. Feed with a high potassium fertilizer in summer.
