Disocactus Anguliger (Fishbone Cactus): How To Propagate and Grow

Fishbone Cactus is not your average cactus. This is a jungle cactus related to orchids and it loves humidity. While it may be slightly different from other cacti and succulents, it is actually a very easy-going plant that beginner gardeners will love practicing their gardening skills on.

How to Identify Fishbone Cactus

Identifying a Fishbone Cactus is a simple task. The long, green leaves of this cactus grow in a zig-zag or the shape of a ricrac trim. This is also the shape of the backbone of many types of fish, hence its name.

Where Does Fishbone Cactus Grow

Rather than coming from an arid, desert region of Mexico, Fishbone Cactus is a native of the tropical rainforests found in Chiapas, Mexico. This is why it enjoys humidity so much.

Uses of Fishbone Cactus

This is a highly decorative plant that is ideal for displaying in hanging baskets. Setting a Fishbone Cactus in a hanging basket allows its long leaves to drape over the edges of the basket with flair and drama.

How to Grow Fishbone Cactus from Seed

Since Fishbone Cactus is a slow-growing plant, it is not usually recommended that it be propagated by seeds, but if this is the way you prefer to grow a Fishbone Cactus, here are the basic steps to follow:

  1. Propagate the seeds outdoors if the weather is warm, but indoors if the weather is cool
  2. Plant the seeds in a seed tray filled with potting soil designed for succulents
  3. Place the seed tray in a sink filled with water so the soil will absorb the water from the bottom
  4. Place the seed tray in a warm area with indirect sunlight
  5. Place a piece of plastic wrap over the seed tray to keep in air humidity
  6. Add water to the seed tray as needed (the soil should be moist but not soggy)

Evidence that the seeds are sprouting will be tiny leaves above the soil.  As soon as these leaves are spotted, the plastic wrap should be removed.

Once the seedlings have grown into healthy plants, the following care must be taken:

  1. Move the new plants to a larger pot, if needed
  2. Feed the new plants with a diluted fertilizer during their growing season.
  3. Water the plants only when the soil is dry.

Fishbone Cactus Growing Conditions

Since this cactus comes from a rainforest setting, its growing conditions are slightly different from most other types of cacti and succulents. Fishbone Cactus will need:

  • Warm, humid air
  • Moist soil
  • Full sun

When to Plant Fishbone Cactus

It is best to plant Fishbone Cactus during warm and sunny months to ensure it grows strong and healthy.

How to Plant Fishbone Cactus

Planting a Fishbone Cactus is similar to planting other types of cacti or succulents; however, there are a few things that you will want to remember when handling one of these plants. When you go to plant a Fishbone Cactus, remember these steps:

  1. Put on a pair of gloves. Fishbone Cactus has tiny spikes on it that can prick your hands.
  2. Select a container that will drain off excess water. An unglazed pot is highly recommended.
  3. Select potting soil that will drain off excess water. These plants may like moisture more than other succulents and cacti, but they don’t do well when the soil around them gets soggy, so provided them with a good succulent/cactus potting soil, such as Birch Seed Soils All-Purpose Succulent Plant Soil.
  4. Fill the selected container with the potting soil.
  5. Create a hole in the potting soil.
  6. Set the plant into the hole.
  7. Cover the plant’s roots with potting soil.
  8. Make sure the plant is securely set in the potting soil.
  9. Water the plant as you would any succulent or cactus.
  10. Set the plant in a warm, sunny spot.

Fishbone Cactus Water Requirements

The water requirements of Fishbone Cactus are not typical of most succulents; however, since this plant is susceptible to root rot, it is best to use the soak and dry method when watering it.  The steps for doing this are as follows:

  1. Fill a tray or a sink with a few inches of water.
  2. Set the plant container in the tray making sure that the water is not so deep that it will run over the top of the container.  The point of watering in this way is so that the roots will soak up the water and the leaves will not get wet.
  3. Let the plant soak in the water for fifteen minutes.  This will allow the root system to soak up water from the bottom of the container.
  4. Take the plant container out of the water.
  5. Place the plant container in a spot where the excess water can drain from the hole in the bottom.
  6. Repeat this only when the soil around the plant is dry.

An important difference between Fishbone Cactus and most other cacti is that its soil should not be allowed to dry out as much. Be sure to check the moisture of the soil often and give it some water when the surface is dry. Also, this plant loves humidity, so consider misting it with a spray bottle or keeping it on a bathroom sink or in a bathroom window where it can enjoy the humidity of a warm shower.

Fishbone Cactus Diseases and Common Problems

The most common issues faced by Fishbone Cactus are overwatering and underwatering.

Fishbone Cactus Treatments and Maintenance

Overwatering

When a Fishbone Cactus gets too much water it can cause root rot and this will eventually kill the plant. The best way to prevent root rot is to learn how to properly water a Fishbone Cactus. But, if your plant is already dealing with the negative effects of overwatering (mushy leaves, yellowed leaves, transparent leaves, leaves that are falling out) then you will need to treat it immediately so that it has any chance of surviving.

Follow these steps to treat a Fishbone Cactus that has root rot:

Dry Out the Plant

Stop watering the plant immediately and set the plant’s container in a place that will allow the soil to drain off any excess water.

If the soil is unable to drain, you will need to remove the plant from the soggy soil, let it dry out for a few days, and then, replant it in dry soil.

Remove the Rotten Parts

Trim off any areas of the plant that are rotting, then allow the plant to callous for a few days.  Without letting it callous, the chances of the succulent surviving are very slim.

Add Sulfur to the Root System

This technique should be done after the plant has been trimmed of all its rotted areas and allowed to callous.  It will require that you dust a little sulfur on its root system to help prevent the spread of microbes.

Behead the Plant

This is the last resort technique, but it may be necessary if any of the plants can be saved.

Underwatering

It is unusual to learn that a cactus can be susceptible to underwatering, but Fishbone Cactus is not a typical cactus. If you begin to notice that your Fishbone Cactus is looking unhealthy (dry leaves, aerial roots appearing more frequently), it is a good idea to check the plant’s moisture levels more frequently. It may be that your Fishbone Cactus just needs a good drink more often, or perhaps, a humidity tray.

Fishbone Cactus Repotting Instructions

This plant can be replanted as a whole plant into a bigger or better container or it can be replanted as a stem cutting to produce a completely new plant. Either way, the steps are simple. Let’s walk through the replanting process now.

  1. Put on a pair of gloves. Fishbone Cactus has tiny spikes on it that can prick your hands.
  2. Select a container that will drain off excess water. An unglazed pot is highly recommended.
  3. Select potting soil that will drain off excess water.
  4. If propagating via a stem cutting, cut off a piece of the stem with a sterile cutting utensil.
  5. Fill the selected container with the potting soil.
  6. Create a hole in the potting soil.
  7. Set the plant into the hole.
  8. Cover the plant’s roots with potting soil.
  9. Make sure the plant is securely set in the potting soil.
  10. If you have planted a stem cutting, there is no need to water until you see that it growing. If however, you have replanted a mature plant, you can water it as you normally would.
  11. Set the plant in a warm, sunny spot.
