Fishbone Cactus Profile

General Information

Fishbone cacti are most recognized for their long, arching stems with serrated leaf nodes that dangle from trees in their natural habitat. These species of desert cacti are found in Mexico, where they grow as an epiphyte in evergreen forests in Guerrero, Jalisco, Nayarit, and Oaxaca, where tropical rainforests provide a damp, humid climate.

Fishbone cactus plants were initially classified as a member of the Epiphyllum genus, but it was recently reclassified as a Disocactus anguliger species. The fishbone cactus has smooth, green leaves with thickly branching branches. It is a unique cactus species. The plant is often ornamental because of its fragrant fall blossoms. This fast-growing epiphyte is easy to grow.


This plant is known as the fishbone cactus because it resembles the bones that make up a fish’s skeleton. 

The word cactus comes from the Ancient Greek word o (káktos), which Theophrastus first used to describe a spiky plant whose identity is unknown. The Fishbone cactus, on the other hand, is a one-of-a-kind cactus. It requires different conditions to survive than desert cactus.


Flowers only occur at their mature time, which is the most beautiful part of cultivating these plants. But their bloom lasts for an extended period, mostly a few days. Late fall or early winter is when the Fishbone cactus blooms. The white or pale yellow flowers open at night and provide a lovely scent. The blooms are frequently several inches long, with numerous petals and golden stamens.

Care Tips

Care tips for fishbone cactus

Light Requirement

It prefers bright, indirect light to grow, although it is versatile and can cope with a little less light. In its native environment, the fishbone cactus thrives as a shrub or tree that receives dappled, indirect light. 

The fishbone cactus thrives in a location that receives several hours of bright indirect light when cultivated indoors. Be mindful that if these plants are suddenly relocated from a shady to a sunny location, they may become sunburned. 

Temperature Requirement

The fishbone cactus thrives in warm and humid conditions since it is native to tropical areas. Your fishbone cactus will thrive in temperatures ranging from 60 to 78 degrees Fahrenheit (15 to 25 degrees Celsius), but don’t let it drop below that in the winter; it cannot take frost. If you reside in a cold-weather climate, you must take precautions. 

Water Requirement

Since Fishbone enjoys moist and humid environments, you may water it just like your other house plants during the growth season. This plant, unlike other cacti, is not native to the dry desert. Make sure it gets enough water, especially during the growing season. 

Water the pot once the top inch or two has dried out. It can tolerate missing water but does not appreciate being bone dry for too long. Keep the soil wet but not soggy. Mist it every now and then to add humidity. Allow the soil to dry out a little more in the winter before watering. It’s critical to determine if you’re under-watering or not.

Humidity Requirement

Fishbone Cactus may thrive in a standard household setting, although it prefers a little more humidity because it thrives in humid conditions. About 60% and above humidity levels. 

They will get a good amount of ambient humidity from being in a more covered place in these conditions, so a kitchen or bathroom in the house would be ideal. We recommend misting it frequently, placing it near a humidifier, or using a pebble tray to improve humidity.

Soil Requirement

A well-drained mix will best simulate the conditions in which these plants develop in their natural environments. This sort of mix allows for greater root aeration, which is ideal for epiphytic plants. 

A combination of 2/3 cactus compost or ordinary houseplant compost with 1/3 perlite, grit, or orchid bark for a high-organic matter mix. It requires wet soil. To improve water retention, mix 1 part peat moss with 1 part perlite into normal cactus soil.

Fertilizer Requirement

Treat your fishbone cactus from early spring through late summer with a half-diluted organic fertilizer or houseplant fertilizer. The fishbone cactus does not require any additional fertilizer throughout the year as long as the potting mix contains organic components. 

Fertilize the plant only while it is actively growing. If the plant isn’t actively growing, don’t fertilize it. If you wish to increase flowering, use a fertilizer with a higher potassium content.

Space Requirement

A mature Fishbone Cactus may grow to be 6 inches tall or 3 feet long, with leaves that can grow to be 8 to 12 feet long, so at least a broad enough room for your plant could suffice. You may either plant it in a pot with enough area to grow on a shelf or in a hanging basket. If the right conditions are met, this plant will be happy in your small garden.

Growing and Planting Tips


Fishbone cactus propagation is quite simple and straightforward. There are different ways that can be used to grow your cactus, either in water or in soil.

Stem Cutting Propagation in Water

When growing fishbone cactus, select a strong stem for your cut. Place the cuttings in a jar with some water. Place the jar in a bright, indirect light and keep an eye on the water. When it becomes filthy, remove it and replace it with new, clean water. Before transferring it to potting soil, please wait until your cutting has a few inches long roots. Maintain it by watering it on a regular basis.

Stem Cutting Propagation in Soil

Select a strong stem for your cut. Plant the cutting in a potting mix-filled container. As the roots grow, keep the potting mix damp but not soggy. Place the pot in direct, intense light. You may also cover the top with a transparent plastic bag to keep the humidity in. After a few weeks, you can gently tug on the cut to test for resistance. You may begin now by taking good care of it.

Divisional Propagation in Soil

Divisional propagation is the quickest and most straightforward way. This procedure is frequently used when the plant is being repotted. Simply split one or more plant portions with different root systems from the main plant. Separate the roots gently, ensuring that the majority of them remain intact. Then, immediately after placing each plant in its own container, begin caring for it.


You may trim your cactus to keep its size and shape under control. It has the ability to grow relatively huge and spread out in all directions. To stimulate healthier growth, remove yellow or decaying leaves as well as plant detritus. To cut the stem, use a pair of clean, sharp scissors. Pruning in the spring or summer encourages new growth and gives your plant a new appearance.

Potting and Repotting

Fishbone cactus plants grow well in well-drained soil. Aside from proper soil, picking a pot made of porous materials like terracotta, concrete, or ceramic can help with drainage. 

Repot your fishbone cactus once or twice a year. To avoid being root bound, the soil also needs to be replenished with all its nutrients. Use a pot that is one size larger than the existing one and has sufficient drainage. If feasible, repot during the growth season (spring and summer).

Problems and Troubleshooting

Problems and Troubleshooting


Overwatering can cause root rot, which leads to mushy stems and plant death. If your Fishbone Cactus has been overwatered, you may notice that the potting mix is quite moist and clumpy. If the potting mix becomes wet, replace it immediately rather than wait for it to dry naturally, which might cause more damage to the plant. Remove any dead leaves or roots to allow your Fishbone Cactus to focus on its growth. Please keep track of how much water you give your Fishbone Cactus each time so it doesn’t end up sitting in wet soil.


Fishbone cactus leaves might wrinkle or shrivel if they are underwater. This plant is succulent. However, unlike other cactus plants, they require regular irrigation. If your Fishbone Cactus seems thirsty, gently water it; if the cactus appears to have wrinkly leaves and is dying, soak it and let it dry to help it recover.

Nutrient Deficiency

This plant needs a lot of nutrients to grow strong and healthy. A nitrogen and potassium deficiency causes your plant’s base leaves or cactus stems to become yellow to light green, limiting its development.

Follow this essential criterion to guarantee that your plant gets adequate nutrients: give your cactus ample light. Use the suitable soil and fertilizer, and take good care of your plant.

Flowering Problems

Fishbone cactus are typically challenging to bloom indoors, and it may take a couple of years to reach flowering maturity. It also requires high light intensity to produce flowers. And lastly, this succulent’s blooms only last a few days. 

To encourage and ensure blooming, the fishbone cactus should be exposed to cold temperatures, regular feeding, watering, and enough of bright indirect light.
