Some moon cacti—but not all—have colored parts that sprout tiny, propagable offshoots. These may be grafted onto “rootstock” cacti like Cereus peruvianus, Hylocereus trigonus, or Trichocereus spachianus.
Using a healthy, rooted cactus (such as any of the aforementioned types), cut off the top so it is only a few inches tall. To do this, use a clean knife to cut off the top portion (or “scion”) you want to propagate. Place the branch where it was cut on your new rootstock.
From there, you can use string or rubber bands to keep them joined. To hold everything in place, wrap it vertically all the way around the plant and pot. Your plants ought to be growing as a single unit in six to eight weeks! Just make sure to keep an eye out throughout that period for any rot or bugs.
Summary
Use a clean knife to cut the moon cactus branch. Place the cut ends of the offshoot and the rootstock together after cutting the top of your rootstock. Give them about two months to unite, and keep them together with a rubber band.

How can a moon cactus be grafted?
Grafts can take many distinct forms. The types of cuts you make and the location of the transplant vary amongst them. Here, we’ll talk about the lateral graft, which is the simplest and most efficient type.
- At the desired height, cut the rootstock’s head off. A minimum of two to three inches above the soil is required. Use a clean, sharp knife, and make the incision as precisely as you can.
- To make the scion, remove the head from your other cactus. Where they will meet, the scion and rootstock should be about the same diameter.
- Take a look at your cacti’s chopped portion. Most likely, you’ll observe a ring or perhaps some dots that resemble tubes. These are the xylem and phloem, which are found in the plant’s vascular cambium. That specific type of plant tissue is in charge of producing new xylem, which functions similarly to blood arteries for plants. As nearly as you can, you should match these rings or the tubes. This is the crucial stage in the grafting process. You should be fine if you manage to match up the sides and have a clean cut.
- Wrap the entire plant in twine or rubber bands to hold the graft in place. from the cactus’s peak all the way down to and around the pot. Never worry about harming the cacti. What’s a little pressure going to do when you just chopped off their heads? If you are unable to keep the pieces together in this manner, you can use a skewer similar to a sandwich toothpick. As with any time you wound a plant, there is a slight chance of infection.
What is the time required to graft a moon cactus?
Because it is a grafted cactus, the moon cactus cannot grow. If you see the top of your moon cactus detaching from the rootstock cactus, use the following actions to re-graft it:
- 1. Take out the moon cactus with care. Cut off the cactus’ vibrant top with a clean knife.
- 2. Trim the cactus rootstock. Cut off the top layer of the old rootstock if you don’t want to utilize it.
- 3. Join the rootstock and moon cacti together. The moon cactus should be placed on top of the rootstock and firmly fastened with twine or rubber bands around the entire plant and pot. After around two weeks, the two cactus will have joined and the rubber band or twine can be taken off.
Does Moon the cactus grow grafted?
In a procedure that involves cutting off the top of the rootstock cactus and the bottom of the Hibotan, the moon cactus is typically sold already grafted. The sliced edges of the two sections are secured together, and they soon heal together. Re-grafting the moon cactus onto a new rootstock will increase its lifespan.
Additionally, it can be grown from seed, although it will take at least a year to produce a usable specimen. Sprinkle some fine sand on top of the seeds after scattering them over a dry succulent mixture. For germination, moisten the flat and move it to a warm area. Replant the seedlings in groups for the best results once they are big enough to be taken out.
Removing the offsets, which are tiny replicas of the parent plant growing from the rootstock, is the more typical way to propagate moon cacti. In cactus potting soil, these easily divide and take root.
How are cactus grafted?
Simply said, a grafted cactus is a single plant created by crossing two species of cacti. By fusing the top cactus (also known as the scion) with the green cactus bottoms, grafting enables two types of cactus to flourish (referred to as the rootstock). The scion receives its chlorophyll from the rootstock, which enables the frequently colorful scion to carry out photosynthesis and survive.
How long do moon cactus live?
Moon cactus are short-lived because they are grafted. Your moon cactus should survive for a few years, possibly longer. However, eventually the two grafted plants will start to separate or split, and at that time the moon cactus will perish unless it is grafted onto a new foundation.
How often do you water a moon cactus?
Since moon cacti are indigenous to dry desert areas, they don’t require a lot of watering. It is preferable to fully water them, let them dry completely, and then wait a little while before watering them once more. This mimics the rare downpours that occur in their natural habitat. They usually only require watering once or twice a month as houseplants, and even less in the winter. The most frequent cause of death for moon cactus houseplants is overwatering.
What do I do with moon cactus pups?
Your moon cactus may start to develop tiny bumps or colored balls on the side that resemble miniature replicas of the plant. These are puppies or babies, not blossoms.
The moon cactus puppies can be propagated, but keep in mind that they won’t be able to survive without being grafted to a host cactus until they have some green or a darker spot on them. If you prefer the way your Moon cactus looks without them, you can either leave them in place or remove them.
Hylocerus undatus or Myrtillocactus geometrizans are typical stock cacti if you wish to try grafting them. In essence, you simply slice a little portion off the bottom of the Moon cactus baby and a slice from the top of the stock cactus, set them together with the sliced regions touching, then tie them together with twine for about a week or two until they bond.
Your moon cactus pup could be able to survive on its own without a graft host if it is a dark-colored type (occasionally dark purple, burgundy, or almost brown looking), or if it has any green on it. To determine if the pup will develop roots, you can pluck it off and place it on top of cactus soil.
Why is my moon cactus growing arms?
The bottom stock cactus will occasionally branch, sending up side shoots that resemble arms. There is no reason not to leave them if you like them, even if you might notice that they begin to grow more quicker than the rest of the plant and may eventually dominate it.
Using a pair of tidy, razor-sharp pruning shears or scissors, you may also clip the side growth. The cut will heal without any issues, and if you’d like, you may plant the cutting in a different container where it will establish roots and grow into a brand-new plant (without the moon cactus on top, of course).
How do you keep a moon cactus alive?
A moon cactus requires little maintenance to be healthy. Overwatering or when they split from their root stock kill the majority of moon cacti. Simply give your cactus some strong indirect light and water it every few weeks once the soil has dried up fully to keep it alive.
Why is my moon cactus dying?
Usually, grafted moon cacti only live for one or two years. This is due to the fact that the moon cactus depends on the graft with its host cactus (the green “stem”), and it will perish if that begins to split or separate.
Overwatering is another common cause of moon cacti death, and you can see it if the green base starts to become brown or mushy.
Why is the moon cactus top turning brown?
When a cactus turns brown, it usually means that it has been overwatered (especially if the brown areas feel mushy or squishy to the touch). However, if the plant has gone for several months without water, it may also mean that it has been underwatered.
It may have been scorched by too much direct sunlight or a grow lamp that was too close if the top of your moon cactus is becoming brown. Moon cactus only require indirect light; direct sunlight can cause them to burn or fade. Simply relocate your plant to a location with less sunlight if this is the case. The brown top won’t go away, but perhaps the healthy tissue that is still there will live and develop.
What kind of rootstock does moon cactus use?
This sweet “A mutant cactus is actually a cross between a rootstock cactus like Hylocereus and a cactus known as Gymnocalycium (the sicon). the word “Typically, the terms “moon cactus” and “orange moon cactus” are used interchangeably, while red forms can also be included.
What is the lifespan of grafted cacti?
A grafted cactus with a brightly colored ball-shaped top is called a moon cactus. These vibrant cacti have gained popularity as compact, low-maintenance houseplants. Typically, the cactus top is an intense shade of red, yellow, pink, or orange. This patterned top has the look of a vibrant cactus blossom. Some of these vibrant cactus plants have tops that are multicolored or variegated, but every one of them has a cluster of tiny, prickly spines that runs along the curved veins.
Gymnocalycium mihanovichii, also known as the moon cactus, goes by the names Hibotan cactus, ruby ball cactus, and star flowered cactus. A grafted combination of two cacti is known as a moon cactus. The green lower cactus might be any type of cactus, while the bright Gymnocalycium mihanovichii cactus at the top is a common cactus. The cactus ball typically ranges in size from 1 to 2 (2.55 cm) and has noticeable ribs on it.
Put the moon cactus in a warm, sunny location to take care of it. The pot needs to have drainage holes and a quick-draining cactus mixture within. Only water the plant thoroughly when the potting soil is completely dry. To cultivate a robust, eye-catching cactus, fertilize regularly in the spring and summer.
Aerated, sandy soil with good water drainage is the best soil for moon cactus plants. A potting mixture can also be transformed into suitable cactus soil by adding pebbles or tiny stones. Like the majority of succulent species, cacti demand an acidic to neutral potting soil.
The ruby ball cactus and other cacti grow slowly, at a rate of between 0.4 to 1.1 (13 cm) each year. Moon cactus plants are typically supplied almost completely developed.
Ten to 200 years are the lifespan of cactus plants. Outside-growing cacti often live longer than interior-growing cacti, but with the right care, your indoor moon cactus plant can flourish for many years.
The moon cactus has a shorter lifespan than the majority of cacti. These grafted cactus often only survive for a few years. Because the rootstock has outgrown the top of the plant, they live shorter lives. You must re-graft the vibrant ball cactus onto the rootstock to increase their lives. You can learn how to take care of your moon cactus by re-grafting it towards the end of this post.
What is killing my grafted cactus?
Yes! If both cacti are still healthy, you may be able to save one of them. Not mushy, still firm, not excessively dark or stained are considered signs of good health.
We will first determine whether your cactus has been overwatered before discussing what may be done to salvage each individual portion of your cactus.
By selecting one of the following, you can move on to the next stage with confidence that you haven’t overwatered your cactus: Rootstock preservation (the green stalk supporting the colorful cactus on top) protecting the Scion (the colorful, spiny top cactus) A Different Way to Save the Scion
Remember that your moon cactus isn’t intended to live for very long, so it’s highly likely that it’s dying (especially if you’ve had it for a while). It might not be related to your care. Perhaps you provided it with the ideal environment!
Has your moon cactus been overwatered?
Your cactus may have been overwatered if more than one of these is accurate:
- Your rootstock is mushy or becoming brown.
- Even though the ground is wet and squishy, you haven’t watered your cactus in the past 24 hours.
- The cactus’s roots are mushy and brown or black when you check them.
- The cactus’ soil does not drain well.
- Prior to letting the earth totally dry up, you have been watering.
If you don’t already, it would be a good idea to check the roots for indications of root rot if you have any of these symptoms (brown or black, mushy roots).
If the rootstock of a cactus with root rot is mushy, there is little that can be done to salvage it. You could move on to the part that describes how to graft the scion onto a new rootstock if the scion is sound and firm.
You do have a choice if the rootstock is not mushy but the roots are rotten. You’ll need to: 1. Remove all brown or black, mushy roots; only the white, healthy roots should be retained. 2. After that, replant in loose soil and stop watering your plant for at least a few weeks. 3. After you water, wait until the soil is completely dry before you water again.
Your cactus will be content if you plant it in well-draining soil and make sure to wait until the earth is totally dry before watering it once more. This assumes that the roots are still white and healthy.
Important Information: If your moon cactus isn’t getting enough light to utilize the water you’re giving it, you should offer it more light. Light is very important to cacti.
They will flourish in windows that face either the west or the east. They will also be content close to a south-facing window. They won’t get enough light if they’re put more than about a foot from a window, and watering them during periods of low light will be problematic.
To make sure it gets adequate light, I keep mine right on the sill of a west-facing window.
To photosynthesize or produce food, the plant utilizes water and light. The water remains there unused since the plant cannot photosynthesize without enough light. When its roots are left in the stagnant water, they develop root rot, which damages the plant.
Saving the Rootstock
Because it is using all of its efforts to nourish the scion, the rootstock is simply unable to sustain itself. The rootstock will callus over and start to support itself if the scion or ball cactus on top is removed.
Here is how to develop your own cactus from the rootstock alone:
- Obtain a good, clean knife.
- Make a clean incision through the Hylocereus undatus cactus below the scion with the knife. You want to get rid of the entire scion. It is acceptable to take some of the rootstock or Hylocereus undatus out as well.
- Place your happy Hylocereus undatus back in a sunny window after the scion has been removed so that it has time to callous over.
- Give it some time and just water it when the soil is dry.
