Moon cactus may seem strange because to their vivid colors, yet they bear pups or offsets just like other cacti. When these puppies are removed and multiplied, they will grow into brand-new plants. I’ve done it countless times in my shop, and I’ll explain (and demonstrate) how to do it here.
It is important to 1) examine the plant’s health, choose a healthy, good-sized pup, 2) twist and turn the pup to break it off, and 3) propagate the pup in order to remove the moon cactus pup from the parent. Grafting, which involves uniting two separate plants to create a new plant, is one of the main methods of propagation.
Should a moon cactus pup be separated from its parent? If I don’t separate the offset of a plant, would the parent plant perish? The solutions are provided below.
How is a new moon cactus planted?
These succulents will develop colorful flowers in late spring or early summer with adequate care.
- 1. Offer the right amount of shade and light. Sunlight must reach the rootstock cactus in sufficient amounts for photosynthesis. Place your moon cactus close to a window, but make sure it only receives filtered light since direct sunlight might be harmful. If you choose to put your cactus on a windowsill, make sure curtains are covering it to prevent it from getting too much direct sunlight.
- 2. Sow your moon cactus in soil that drains properly. Root rot or mealybugs might result from overwatering a moon cactus. For moon cacti, potting soil mixture is suitable; alternatively, you can amend the soil with perlite or coarse sand to increase drainage. To aid in the drainage of extra water, choose a porous clay pot with drainage holes.
- 3. Don’t overwater your moon cactus. The moon cactus doesn’t need a lot of water, like many other cactus species. After giving the soil a good soak with water, let it air dry entirely. Wait about a week before watering the plant again after the soil has dried out. Only during the growing season, and not throughout the winter, should the moon cactus be watered.
- 4. Position your moon cactus in a warm area. A area where the temperature does not fall below 60 degrees Fahrenheit is the best option. A moon cactus can be kept outside throughout the summer, but you must bring it inside during the winter because frost will kill it.
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.
How can you transform a puppy into a cactus?
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 young cactus be cared for?
Give them a drink, but not too much, and take long intermissions. “Because they store water in their stems, cacti are famed for surviving with little to no watering. That doesn’t imply they don’t require any watering, either. Make sure to inspect the soil periodically. It’s time to water the plant if the top two to three inches of soil are dry “says Palomares.
Thon reiterates Palomares’ counsel and adds: “The temptation to over-water cactus can cause root rot and scab, which manifests as rusty-colored, corky regions on the stems, which is why most people fail at growing cacti. My recommendation is to under-water; you can typically bring them back from the dehydration stage without any problems.”
How quickly do moon cacti expand?
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.
How frequently do moon cacti need to be watered?
Moon cacti aren’t the thirstiest of plants and don’t require a lot of watering, like the majority of cacti and succulents. According to Baldwin, you should only water them every two weeks or so, letting the soil dry out in between.
Your moon cactus may require even less watering over the winter, especially if it is older than a year. You can detect when your young one is thirsty if you follow the instructions in our scrumptious watering guide.
Your moon cactus should be in a pot with drainage holes, as with all plants, to avoid moisture buildup and root rot.
Summary
Moon cacti only require watering every two weeks (maybe even less in the winter), and the soil should totally dry out in between applications.

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.
How are cactus pups made to root?
Amazing plants, cacti generally grow slowly and have extended lifespans. The day comes for many cactus aficionados, though, when they want to begin propagating their cacti. To share it with friends and family, to start growing fresh cactus because of an illness, or to add to the collection of cacti. We will provide you with a comprehensive tutorial on how to propagate cacti from seeds, stem and leaf cuttings, offsets, and share advice in this post. You will be able to discover brand-new techniques for growing cacti.
Propagating cacti by dividing offsetsthe easiest way
Cacti can be multiplied vegetatively by diving their offsets. Vegetative propagation is the process of a parent cactus producing an offset asexually without the use of seeds.
An identical offset, which is typically a small cluster, is produced by the parent plant and can be divided to form a new cactus. Cacti can be spread most easily using this method.
An offset is typically quite simple to divide, and it will establish itself fast and often successfully. When you separate small offsets from a mother plant, many of them already contain tiny roots.
Not all species of cactus can generate offsets, however many of them can. It would be relatively simple to spread cactus without using seeds if they could all reproduce by offsets. Some cacti can generate offsets, but because the plant is so little and delicate, it is not advised that you separate them. Small offsets help these cacti grow and look better.
You shouldn’t divide/cut offset from the following cacti:
- The peanut cactus, Lobivia silvestrii
- small (note that you can cut offsets for big species) Genus Gymnocalycium
- Tephrocactus
- Echinocereus, a genus of bigger shrub cactus, including species like Echinocereus engelmannii.
- small-scale Rebutia cacti
This is Rebutia heliosaone of the plants that you avoid propagating with offsets
As it can affect the cactus’ growth and integrity, it is often preferable to reproduce these cacti in other ways.
You can propagate cacti from offsets with these cacti:
- Your offset-propagating cacti should be big, rounded, and clump-forming. It is ideal for offsets to be at least the size of a little ball and the primary parent cactus to be huge. These cacti grow “separately,” and the pups on them don’t have a nice appearance.
- For instance, the majority of Mammillaria or huge Echinopsis eyriesii are ideal. Numerous additional species are equally appropriate. Please refer to our individual care papers if you have any questions.
Cacti that don’t produce offsets/pups:
Many cacti don’t normally generate pups or offsets. These include, for instance:
- big cacti with a barrel form, like those in the genus Ferocactus.
- Others include the genus Astrophytum of cactus,
- Parodia,
- as well as numerous others.
Offsets are unusual for these cacti. However, in the event of wounds, damage to the root system, cold, etc., they can still create offsets to preserve themselves. Some individuals propagate uncommon cacti in this way. However, most cacti create offsets, and it’s usually easy to divide them apart for fresh growth.
How to propagate cacti using offsets/pups:
- In late spring or summer, cut the offsets from the main parent plant.
- The offset ought to be between 1.5 and 2 inches long. Higher offsets on the parent cactus typically have stronger and healthier offsets.
- You will need to either cut the pup/offset free from the parent plant with a knife or disconnect it manually.
- To see where a parent plant and a pup are connected, remove the soil from the offset’s top.
- It could be simpler to manually disconnect the offset
- Simply take a pup, turn it around, and gently break it till it falls off.
- You can use a knife if that doesn’t work. Cut the knife at the connecting place after sterilizing it (with boiling water or alcohol).
- Cut off any remaining parent plant material from the pup using a clean knife. If not, it will decay and harm the pup.
- After that, you must allow your pup to dry for around three days before planting it. The pup can be dried most effectively by being positioned vertically in a vacant container with drainage holes. If the offset isn’t dried, any wounds won’t heal in time for planting and will instead degrade the soil.
- When you cut off any cacti offsets from the parent plant, their roots will develop organically (most Echinopsis cacti, for example).
- A cactus pup without roots can be placed in dry soil with some gravel for a few days or even up to a week before it begins to grow roots. Alternatively, you might put your cactus in a pot with perlite, some ground charcoal, and sand so that it can develop roots. With small-rooted offsets, skip this step.
- Set up the soil and container for your new cactus. Before adding soil, remember to utilize the proper containers and drainage. Learn how to make cactus soil and select the best container here.
- Place a pup in the ground, but don’t bury it too deeply. The dirt should only cover one-fourth of the stem.
- Deep under the stem, some adult cactus generate very tiny pups. These puppies will frequently be little and receive less light. These pups should be dried for a few days before planting in order to separate them. After leaving them in the shade for several days, gently move them to a lighter location.
- After planting, don’t water the cactus right away! 5-7 days should pass before watering. By doing this, you will reduce the possibility of rotting and infections.
That’s basically all for growing and dividing cacti from offsets. This is the simplest method for propagating cactus, and if you choose to use it in the late spring or summer, you shouldn’t encounter many difficulties. Ensure that pups are dry before planting.
Propagating cacti with stem and leaf cuttingsthe second best way
The second best method of cacti propagation uses stem and leaf cuttings. By straightforward division, this method of propagation is also vegetative. Cutting propagation is comparable to pup/offset propagation. This method of reproduction is quite helpful when a cactus is growing too large and unsightly, or if it is, for example, beginning to decay. A nice approach to share your cactus with friends or family is through stem/leaf cuttings.
- Approximately 7 days after watering your cactus, take cuttings in the spring or summer.
- Selecting healthy, non-dry, uninfected cactus portions is the first step.
- To reduce the risk of infection, clean a knife or blade with rubbing alcohol in this manner.
- With a knife, slice the leaf or stem portion across the joining point.
- If the object comes off of the cactus loosely, you can avoid needing a knife to make the cut. Try to remove a leaf with a base by gently pulling it from side to side.
- Apply some horticultural charcoal like this to the base of the cutting and a piece of a cut cactus to avoid infection of the plant and the cutting. To stop the chopped area of your cactus from drying out, you can even cover it with a piece of paper or fabric.
- It is now crucial to use a knife to “sharpen” the end of the cutting base. Cut the base’s edges with a knife that has been sterilized. Sharpen the edge by slowly slicing across the cutting base, just as you would with a pencil. This is crucial because if the cutting is allowed to dry, the roots will draw back inside the skin at the location of the cut. Even while a blunted cutting will develop more quickly, its roots will only grow from one side and will be too feeble to support the plant’s stem for an extended period of time. This is so that there won’t be any root growth from the plant’s center.
- However, if you sharpen the cutting edge, roots will begin to sprout from the center of the plant, building a stronger root system for long-term success.
- The cutting should be dried. Once you pot them, this will help them develop more effectively. Drying should only be done vertically for 10-14 days for thick/large clippings and 5-7 days for little ones. It can be hung or put vertically in a container that is empty. Your cutting will begin to develop tiny roots on that side if you place it on a table (horizontally), which will result in permanent harm. Because the roots on this cutting are coming out of the side rather than the base, it cannot be potted. Therefore, only dry them vertically. The pot can be topped with a few rocks if you have a flat cutting.
- Place the base in the temporary substrate so that it can begin developing roots if you notice that the base is becoming coated in callus (a dried wound) or after a general drying period. Sand, charcoal, and peat should make up the majority of the temporary substrate.
One method of growing cuttings Sand and charcoal make up the top white layer, which is followed by soil and drainage level.
- Roots should start to show after around two weeks. At this point, a cactus can be repotted into a typical substrate like this cactus and succulent mix. More information on creating cactus soil may be found here.
You can chop off the healthy top of a cactus and develop a new cactus if any portion of the plant is sick or rotting. To preserve a dying cactus, a stem cutting will be used. As previously mentioned, use a sharp knife to cut and sanitize the cutting edges.
