Weberbauerocereus johnsonii

Weberbauerocereus johnsonii is a columnar cactus native to the dry valleys and rocky slopes of Peru. It can grow into tall, branching stems that may exceed several metres in height, with a grey-green epidermis and well-defined ribs lined with clusters of stout spines. The spines vary from pale to golden brown and provide protection from intense sunlight. In summer, mature plants produce large, tubular nocturnal flowers, typically white, that emerge near the stem tips and open at night to attract pollinating moths or bats. With age, plants may develop a woody base and a more tree-like form.

Care Tips:

• Light - Requires full sun to light shade; strong light maintains spine colour and promotes healthy growth.
• Water - Water deeply but infrequently during the warm growing season; allow the soil to dry completely between waterings. Keep almost dry in winter.
• Humidity - Prefers arid conditions and excellent air circulation.
• Media - Use a sharply draining cactus mix with added coarse sand or pumice.
• Temperature - Thrives between 15-30 °C; protect from frost and prolonged cold combined with moisture.
• Fertiliser - Feed monthly with a low-nitrogen cactus fertiliser during active growth; do not fertilise in winter.
• Repotting - Repot every 3-4 years or when outgrowing its container; handle carefully due to spines.
