Fishbone cactus, also known as Epiphyllum anguliger, is a unique and beautiful houseplant that can add a touch of exoticism to any indoor space. Caring for a fishbone cactus is relatively easy, as it is a low-maintenance plant that can tolerate a range of conditions. Here are some tips on how to care for a fishbone cactus indoors:
1. Lighting: Fishbone cactus thrives in indirect light, preferably bright but not direct sunlight. Place your plant near a window with filtered light or in a spot where it can receive bright, indirect light for several hours a day. However, be cautious of too much direct sunlight, as it can scorch the leaves.
2. Watering: Like most cacti, fishbone cactus prefers to dry out between waterings. It is important to water the plant thoroughly and then allow the soil to dry out completely before watering again. Overwatering can lead to root rot and other issues, so it’s better to underwater than overwater. During the growing season (spring and summer), water your fishbone cactus once a week or when the top inch of soil feels dry. In winter, cut back on watering to about once every two to three weeks, as the plant’s growth slows down.
3. Soil: Fishbone cactus prefers a well-draining soil mix that mimics its natural habitat. A mix of potting soil, perlite, and orchid bark or sand will provide the right balance of moisture retention and drainage. Avoid using heavy or compacted soils, as they can retain too much water and lead to root rot.
4. Temperature and Humidity: Fishbone cactus thrives in average room temperatures between 60-75°F (15-24°C). It can tolerate slightly cooler temperatures in winter but should be protected from frost. As for humidity, fishbone cactus can adapt to a range of humidity levels, but it generally prefers moderate humidity. In drier environments, you can increase humidity around the plant by placing a tray of water nearby or using a humidifier.
5. Fertilizing: Fishbone cactus is not a heavy feeder and does not require frequent fertilization. During the growing season, you can fertilize your plant once a month with a diluted balanced houseplant fertilizer. Be sure to follow the instructions on the fertilizer package for proper dilution ratios. Avoid fertilizing during winter when the plant is dormant.
6. Pruning and Propagation: Pruning is not necessary for fishbone cactus, but you can trim off any dead or damaged stems to maintain the plant’s appearance. Fishbone cactus is relatively easy to propagate. You can take stem cuttings and allow them to callous over for a few days before planting them in a well-draining potting mix. Keep the cuttings slightly moist until they develop roots, which usually takes a few weeks.
7. Pests and Diseases: Fishbone cactus is generally resistant to pests and diseases. However, it can occasionally be susceptible to mealybugs or fungal issues if overwatered. Inspect your plant regularly for any signs of pests or diseases, such as webbing, sticky residue, or wilting leaves. If you notice any problems, treat them promptly with organic insecticidal soap or a suitable fungicide.
In my personal experience, I have found that fishbone cactus is a relatively forgiving plant that can tolerate a bit of neglect. However, providing it with the right amount of light, water, and well-draining soil will ensure optimal growth and health. I hope these tips help you care for your fishbone cactus and enjoy its unique beauty in your indoor space.
