Houseplant of the Week: cobra cactus
Why will I love it?
The Opuntia zebrina f. reticulata is an unusual cactus due to its distinctive crisscross markings on the pads, which give it a unique, snakeskin-like appearance. With its irregular shapes and sculptural form, this cactus is a living piece of art that requires very little maintenance.
Light or shade?
It thrives in full sun.
Where should I put it?
Given its love for bright light, place it in a sunny spot such as a south-facing windowsill, sunroom or conservatory, where it get the attention it deserves.
How do I keep it alive?
Avoid overwatering. Let the soil dry out completely between waterings. During the growing season (spring and summer) water it every week, reducing to just once a month in winter, and use a well-draining cactus soil mix. Adding extra drainage materials such as pumice or perlite will help keep the roots dry and prevent rot. This cactus loves warmth, thriving in temperatures of between 10-30C, but it can tolerate a room as low as -5C if the soil remains completely dry. Use a cactus fertiliser once a month during the growing season but stop feeding in winter when the plant goes dormant.
Did you know?
The cobra cactus doesn’t exist in the wild – it was cultivated in a plant nursery for its striking appearance. Like other members of the Opuntia family, it produces small, colourful flowers, but its real allure comes from its intricate and rugged form.
