The Fishbone Cactus (Epiphyllum anguliger), also known as the Ric Rac or Zig Zag Cactus, is a stunning houseplant that adds a quirky and tropical vibe to your home. Known for its unique, zig-zag-shaped leaves that resemble a fish skeleton, this cactus is native to the tropical rainforests of Mexico, where it thrives as an epiphyte. Unlike traditional desert cacti, the Fishbone Cactus prefers a more humid environment and slightly different care. Here’s a comprehensive guide to keeping your Fishbone Cactus healthy and vibrant.
The Fishbone Cactus thrives in bright, indirect light. While it can tolerate some direct sunlight, too much can scorch its leaves. An east-facing window is ideal, where it can enjoy soft morning light. If you don’t have enough natural light, a grow light can help provide the plant with the brightness it needs to thrive. Avoid placing it in low-light conditions, as this may slow its growth and reduce its chances of blooming.
Unlike desert cacti, the Fishbone Cactus prefers moderately moist soil. Water your fishbone cactus thoroughly when the top inch of soil feels dry, allowing excess water to drain out of the pot. Be careful not to let the plant sit in standing water, as this can cause root rot. During the growing season (spring and summer), water more frequently, but reduce watering in the cooler months when the plant’s growth slows.
The Fishbone Cactus thrives in well-draining soil. Use a potting mix designed for epiphytes or create your own potting mix by combining regular potting soil with orchid bark, perlite, or sand. This mimics the plant’s natural environment and prevents waterlogging. A pot with drainage holes is essential to keep the roots healthy. Repot the plant every 2-3 years or when it outgrows its container, ideally in spring.
As a tropical plant, the Fishbone Cactus prefers warm and humid conditions. It thrives in temperatures between 60-80°F (15-27°C) and doesn’t tolerate frost. If your home is dry, especially during winter, increase humidity by misting the plant, placing it near a humidifier, or setting it on a pebble tray filled with water.
Feed your Fishbone Cactus during its active growing season with a balanced, water-soluble fertilizer diluted to half strength. Fertilize once a month from spring to early fall to encourage healthy growth and flowering. Reduce or stop feeding during the winter months when the plant is dormant.
Pruning helps maintain the shape and health of your Fishbone Cactus. Remove any yellowing, damaged, or overly long stems using sterilized scissors or pruning shears. Pruning can also encourage new growth and make the plant bushier.
The Fishbone Cactus is easy to propagate through stem cuttings. Simply cut a healthy stem segment, let it dry for a day or two to form a callus, and then plant it in a well-draining potting mix. Keep your plants soil slightly moist until roots develop, which usually takes a few weeks. Propagation is best done in the spring or summer when the plant is actively growing.
The Fishbone Cactus is considered non-toxic to pets, making it a safe choice for households with cats or dogs. However, it’s always a good idea to discourage pets from chewing on the plant to prevent accidental damage.
One of the most exciting aspects of the Fishbone Cactus is its fragrant, star-shaped flowers that bloom at night. To encourage blooming, ensure the plant gets enough bright, indirect light and a consistent care routine. Cooler temperatures (around 60°F or 15°C) in the fall can also trigger flowering. Be patient, as it may take a few years for a young plant to bloom.
