For the succulent collector, there is practically no end to the variety of cacti and succulents’ sizes, textures, colors, and shapes. Gymnocalycium mihanovichii or Hibotan cactus are the scientific names for moon cactus plants. The plant, strangely enough, is something of a mutant and is unable to make chlorophyll, necessitating grafting onto a rootstock that can. The growing instructions for a moon cactus are similar to those for other succulents, however even with proper care, these plants only live for a limited time.
How natural are moon cacti?
Hibotan cacti are found naturally in desert environments throughout South America. More than 80 species can be found in Bolivia, Brazil, Paraguay, and Argentina. They are a vibrant group of succulents that are unable to create plant sugars through photosynthesis due to a lack of chlorophyll. Since the moon cactus needs a lot of chlorophyll to survive, the plants are grafted onto a species that produces a lot of it.
Moon cactus plants are available in a variety of vivid hues, including hot pink, blazing orange, and even a nearly neon yellow. They make wonderful window boxes or houseplants for southern exposure and are frequently marketed as gifts. Although some cultivars can grow up to 8 inches (20 cm) in diameter, these are typically little plants that are only 1/2 inch (1 cm) across.
How many years do moon cacti have?
A Moon Cactus can live for one to three years on average. There are a few anecdotes, though, of succulent keepers who have preserved specimens for considerably longer than five years. However, it is not uncommon for a Moon Cactus to only last a few months, particularly if you are unfamiliar with taking care of one.
What location should I give my moon cactus?
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.
What makes it a moon cactus?
South American cacti include Gymnocalycium mihanovichii.
[2] The most often used cultivars are different mutants that have no chlorophyll at all, revealing the red, orange, or yellow pigmentation. The resulting plant is known as a “Moon Cactus” and is frequently grafted with these mutant strains onto the hylocereus cactus. [3] [4] [5] [6] Moon cactus, also known as Ruby Ball, Red Cap, Red Hibotan, or Hibotan cacti, are frequently grown as indoor plants.
Are moon cacti parasitic?
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.
Can moon cacti be grown inside?
The majority of succulents and cacti can be grown and cared for similarly to Moon cacti species. Moon cacti won’t be a problem if you already know how to grow succulents and other types of cacti. They can only survive for a few years, even with proper care. But it’s all worth it because of them!
They are hybridized versions of two cacti species with differing lighting needs. They are in a parasitic relationship, even if they both grow together. Their requirements must be satisfied in order to keep them both healthy. The colored cactus on top will not withstand direct sunshine, whereas the lower green cactus generally enjoys light.
When cultivating these cacti, be careful to give them plenty of partial shade in an area that is just a little bit bright. The top layer may eventually lose its color if it is exposed to too strong, direct light.
Like many cacti, the Moon Cactus can endure extended droughts and thrives in desert-like environments. It can thrive in temperatures about 80 degrees Fahrenheit indoors, but you should keep it away from temps below that (4 C). A thin blanket or sheet can be a highly effective wintertime protection for moon cacti since frost would kill them.
You should select a potting soil blend that is excellent for the bottom cactus when planting a Moon cactus for the first time. Typically, the host favors a mix of cactus soil that is low in pH, fast-draining, and rich in organic content (acidic to neutral).
Although these cacti don’t really require fertilizers, they do appreciate a nice feeding from April to September when they are actively developing. Once a month, you can fertilize your plant with a cactus fertilizer, and you shouldn’t fertilize throughout the winter.
The ideal time to repot your Moon cactus is in the spring or summer. Take the cactus out of the pot gently after the potting dirt has completely dried out. Trim any rotten or dead roots, and remove extra soil from surrounding your cactus.
Make careful to apply a fungicide to any cuts if any were done. Your Moon cactus should be planted in the container with its roots spread wide and filled with fresh cactus potting soil. Because immediate watering can trigger root rot, wait about a week before watering your newly potted cactus.
Although these cacti are not very susceptible to pests, mealybugs or spider mites may occasionally appear. You must quarantine your cactus if you suspect an infestation and exterminate any insects with a cotton cloth dipped in rubbing alcohol. Additionally, systemic pesticides or highly concentrated contact insecticides can be used to control these types of infestations.
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 frequently should a moon cactus 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.

Should my moon cactus be repotted?
The majority of moon cactus plants are created by grafting Gymnocalycium mihanovichii to a Hylocereus rootstock. While the Gymnocalycium does not create its own chlorophyll and is dependent on the Hylocereus for help in making food, the Hylocereus is a plant that does. These tiny cacti don’t need to be replanted very often, but you should be aware of when and how to do it at least every three to four years if not more frequently.
Cactus plants typically flourish in harsh environments with rocky terrain and low fertility soil. They can fit themselves into tight spaces where there is little area for roots and appear to enjoy it. A potted cactus, on the other hand, likes to be crowded and only needs about an inch (2.5 cm) of space between it and the edge of the container.
Changes in soil are typically made to moon cactus pots. The plant will start to grow roots out of the drainage holes if a new container is required. This is a signal that the plant needs to be placed in a fresh, slightly larger container so it can expand. Select non-glazed, well-draining containers. This is done to permit any extra moisture to evaporate, which is crucial for cactus care.
