Some cacti can be multiplied by harvesting the offsets and placing them in the ground to allow them to take root naturally. For some species, it’s necessary to remove a shoot, let it calluse, and then plant it till roots form. It’s not the case, though, with the moon cactus. The mutants with pure neon hues can only be propagated using the grafting technique.
The Pup as a Scion
Offsets of the moon cactus (the pup) begin as a little hump that resembles the appearance of their mother plant. They have small, delicate, pointy spikes that are neatly curled up, and they are as colorful and vibrant as their mother. They only rely on the rootstock for support, therefore they develop slowly.
They cluster together around the main plant’s ball-shaped body. They can stay with their mother if you want to. But removing them from their mother will prevent the plant from going without nutrients and dying. When moon cactus puppies are a good size and ready for grafting and propagation, I advise removing them.
The Ideal Rootstock
Make sure to pick a healthy rootstock while grafting. Straight, green, chunky, pest-free, and fungus-free rootstocks are indicators of good health. These qualities make a rootstock hardy, able to survive harsh environmental conditions like drought.
To function efficiently and provide adequate nourishment for itself and the scion, the rootstock must be healthy and juicy. The rootstocks Hylocereus, Cereus peruvianus, Stenocereus, and Myrtillocactus are specifically compatible with Gymnocalycium. They are a great choice for rootstock due to their thick and robust qualities.
How to Propagate Moon Cactus Pups
Purely yellow, red, pink, or orange moon cactus puppies can only grow after being grafted. Since they have no chlorophyll in their bodies, they are unable to be rooted directly in the soil. The base cactus serves as their host in order for them to survive.
How can a cactus be grown from a pup?
It’s time to pot up offsets from cacti after removing them and letting them callus. The ideal medium is grippy and well-draining. You can buy cactus mixes or make your own by mixing 50 percent peat or compost with 50 percent pumice or perlite.
Cuttings only require a pot that is slightly larger than their base diameter. In order to prevent the offset from toppling over, cover one-third to one-half of the base with the medium. Keep the medium mildly moist and place the pup in indirect but bright sunlight.
Although some cacti can take months to root, most do so in four to six weeks. By observing any fresh green growth, which shows that the roots have taken hold and the plantlet is receiving nutrients and water, you may determine when it has rooted.
How should a moon cactus cutting be taken?
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 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.
Can you grow young cacti?
Because it doesn’t include the transfer of seeds, cactus pup propagation is a vegetative method of plant propagation. You employ an offset, which is produced asexually by the parent plant, to create a new plant.
The pup develops as a little clump that is simple to separate from the parent plant and use to create a new cactus. This is most likely the simplest way to spread cacti. The majority of the time, it is rather simple to separate the pup from the parent plant, and it will establish itself fairly fast and frequently with success.
Most of the time, the pups will have a limited number of their own roots. Sadly, not all cacti species can give birth to pups. Make sure your garden’s cactus species can produce offsets before choosing this method of propagation.
Types of cacti that grow pups/offsets
Offsets are produced by many cacti of the barrel and rosette varieties. Large barrel cacti typically produce the largest pups, making them one of the greatest succulent species to multiply through this technique. The barrel cactus has a special technique of giving its offsets nutrients and water while protecting them from the harsh sun.
The majority of pups develop at the plant’s base, although some may also appear throughout the stem or even on the pads. Any of these offsets can be taken out and rooted in a container so they can develop into new plants.
As long as you make clean incisions and give the offsets time to calluse before rooting, propagating cacti from offsets or pups is simple and quick.
In general, cacti plants that you should think about growing from pups ought to be big, rounded, and clump-forming. The offsets must be at least the size of a tiny ball, and the parent plant must be substantial.
How is a puppy reproduced?
Succulents can also grow from solitary leaves. Succulent cultivars with fleshy, plump leaves that are simple to remove function well with this technique. Leaf propagation spares less of the “mother” plant and each leaf can create numerous little plants, even though it will take much longer to produce a full-sized plant. Getting a quality leaf cutting is crucial, much like with stem cuttings. Although they must split from the plant at the base of the stem, leaves can be wiggled off of a plant. Kremblas advises caution, saying, “Be sure to reach all the way down to where the leaf joins the stem, as a broken leaf will not propagate.” And make sure to select a leaf that is firm, plump, and limp-free.
Leaf cuttings should be allowed to callus and need partial sun to grow, just like stem cuttings. Leaf cuttings should be placed on top of a thin layer of succulent potting soil (not buried), and they should be misted with water to keep them wet. The leaf cuttings will start to grow little “pup” plants in about three weeks. The mother leaves will start to wilt and drop off after eight weeks, at which point your pups are ready to be planted.
Can the top of my moon cactus be chopped off?
Hibotan cactus is another name for the moon cactus (Gymnocalycium mihanovichii). It is actually a cactus that has been grafted from two separate species.
Grafting is the process of fusing the tissues of two different plant species so that they can develop together.
Because it lacks chlorophyll, the top portion of the moon cactus (the vibrantly colored ball) is unable to make its own food.
The top part is unable to create enough food on its own to support itself. It survives and thrives by using the lower cactus’ capacity for food production.
What is the top cactus (scion)?
Gymnocalycium mihanovicii friedrichii, sometimes known as a chin cactus, is the cactus on top.
The ball cactus on top is referred to as the scion when people or businesses are making these cacti.
What is the bottom cactus (rootstock)?
The cactus at the bottom is a Hylocereus undatus, sometimes known as a pitahaya or dragon fruit.
The bottom cactus is referred to as the rootstock supporting the scion while moon cacti are being created.
Why is this cactus not destined to survive long?
Because the scion acts as a parasite on the rootstock, the moon cactus cannot endure for very long.
The rootstock is unable to continuously support the scion and itself through food production.
When a result, as the rootstock tries to maintain both of them over time, it gradually becomes weaker from lack of nutrition and eventually dies, which results in the death of both cacti.
How long will moon cactus live?
Because we don’t know how long they were alive before we bought them, it’s difficult to provide an answer. Before a person’s health begins to deteriorate and eventually leads to death, it seems typical for them to have moon cactus for anywhere between 1.5 and 3 years.
Deaths from overwatering and/or lack of light typically occur more quickly than this, which may help you figure out what is ailing your cactus.
A moon cactus can be grafted, but how?
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.
What two plants make to a moon cactus?
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.
