Plant Description

Description

Selenicereus wercklei, commonly known as Werckle’s Moonlight Cactus, is an unusual tropical cactus with long, trailing or climbing stems that make it ideal for hanging pots and elevated shelves. Unlike traditional desert cacti, it naturally grows in humid tropical forests, where it climbs through trees and produces impressive nocturnal flowers when mature.

PLANT CARE

Everything you need to know to keep your plant happy and thriving.

☀️

LIGHT

Medium Light

💧

WATER

Moderate watering. Allow the upper section of compost to dry slightly between waterings, then water thoroughly and allow excess water to drain away. Keep slightly more moist during spring and summer and reduce watering during winter.

🌱

SOIL

Free-draining epiphytic cactus mix containing houseplant compost, orchid bark and perlite. It needs more moisture retention than a traditional desert cactus mix while still requiring excellent drainage.

🪴

REPOT

Repot every 2–3 years in spring or when noticeably rootbound. Move up only one pot size at a time and use a container with good drainage.

JOE'S TOP TIP

Treat this more like a tropical jungle cactus than a desert cactus. Give it bright, indirect light, good humidity and more regular watering than traditional cacti. Allow the stems to trail naturally from a hanging pot or provide support if you prefer a climbing plant.

⚠️

COMMON MISTAKE

Keeping it extremely dry because it's a cactus. Selenicereus naturally grows in tropical environments and appreciates more consistent moisture than desert species. However, permanently wet compost can still cause root rot.

PLANT FACT

Selenicereus species are often called Moonlight Cacti because many produce spectacular flowers that open during the evening or at night. The flowers are adapted to attract nocturnal pollinators such as moths and bats.
