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.
The function of a moon cactus
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.
Are there really moon cacti?
Undoubtedly, many of you have already encountered this fascinating cactus. I’m sure some of you have one. These cacti, often known as “Hibotan” or “moon cacti,” are actually two separate cacti that have been grafted together rather than being a single species.
Gymnocalycium mihanovichii is the scientific name for the bright top portion. Both Paraguay and a few areas of Argentina are home to it. It is not nearly as colorful in the wild. The examples that are offered for sale in garden supply stores throughout the world are actually mutant species that lack chlorophyll, exposing other colours that are typically covered by green. These mutants can have a variety of colors, including deep purple, deep red, and yellow. These mutants would ordinarily perish as seedlings without chlorophyll.
Someone eventually had the brightly colored mutants grafted onto several species of cacti, with the hope that they may survive. Exactly this is what has happened. The bottom host cactus is interestingly not even in the same genus as the moon cactus. Most frequently, a species of Hylocereus is used for grafting (the same genus responsible for dragon fruit). I have no idea how or why this host was selected. Regardless, I hope that after reading this you have a newfound respect for these incredibly indestructible house plants.
Can moon cacti be housed inside?
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.
How long are moon cacti alive for?
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 size can a moon cactus reach?
- These species’ most prevalent cultivars are various mutant variants. To create unique specimens, growers frequently graft these cacti onto different cacti.
- These cacti can have red, yellow, or orange coloring, but they are unable to synthesize chlorophyll.
- Gymnocalycium Mihanovichii is the colorful portion (the scion) of the Moon cactus, although any species of cacti can serve as the lower host, albeit Hylocereus cacti are most frequently used.
- Although many people mistake Moon cacti’s top layer for their blooms, if you are persistent enough, they can blossom. Their blooms are incredibly lovely and come in various colors of pink.
- Moon Cacti can grow to a variety of heights depending on the rootstock, but they typically stop growing after they reach about 4 inches (10 cm). The Moon cactus has a diameter of 1.1 to 1.9 inches (3-5 cm).
- They typically have 8 to 14 ribs with narrow margins and a tiny notch. They have weak, flexible, somewhat bent, and yellowish-grey thorns, usually 5–6 in number.
- They can be combined with the Schlumbergera species, sometimes known as the Thanksgiving, Christmas, or Easter cactus, as both have comparable environmental requirements.
How frequently do I need to water a moon cactus?
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.

When should my moon cactus be repotted?
Moon cacti are well-liked indoor plants. To achieve the colorful top part, which is caused by a mutation in the grafted part, they were created by grafting two separate plants. When ought to moon cactus be planted again? Although the moon cactus tends to be very crowded and only needs a new container every few years or so, spring is the optimum time to repot it. However, fresh soil is advantageous because aged soil would eventually lose its texture and minerals.
Moon cacti can they grow outside?
The moon cactus doesn’t need a lot of water. They are not the kind of plant that need frequent watering. Furthermore, when these plants are not exposed to excessive rainfall, they perform substantially better. If you have moon cactus outside and live in a location where it frequently rains, they will fare considerably better if they are placed under a covered porch. Generally speaking, you can assess whether your plants need watering by touching the soil. Your moon cactus will definitely benefit from a light watering if the soil is dry and dusty. not excessively. Never overwater to the point where the dirt in the pot becomes mushy and runs over the sides of the pot. Never water your moon cactus until it is submerged in a puddle of damp dirt. Additionally, it is advised to entirely stop watering elder moon cacti—those that are a year old or older—during the winter months. A young moon cactus plant, on the other hand, just needs a little bit of water over the winter.
Keep in mind that the moon cactus needs water and shallow, unglazed pots with sufficient drainage. Make sure the pots or containers you use have enough drain holes for the water to flow out and down. Before adding your moon cactus, it’s also a good idea to add a thin layer of gravel to the bottom of your container. Water drainage will be helped by the gravel.
Can you remove the moon cactus’s top?
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.
How is a moonstone succulent maintained?
Make sure to provide your Pachyphytum Oviferum the ideal growing conditions if you choose to grow it indoors in a container. You must first learn how to move it into a container, though. First, fill the bottom of your plant pot with gravels before adding potting soil designed especially for succulents.
You don’t need a very deep container to plant your Pachyphytum Oviferum; if your succulent is 2 inches tall, a 2.5-inch container is a suitable option. Since moonstones can spread up to 12 inches wide, your plant pot can progressively increase in size as your plant matures to 8 to 12 inches in diameter. Pachyphytum Oviferum thrives in containers of this size because they allow the striking succulent to expand as it grows. After you have finished positioning the container, insert the stem of your Pachyphytum oviferum as deeply as possible.
After that, water your plant thoroughly and cover the soil with a layer of black pebbles to give it a more appealing appearance. Keep your plant in a bright area where it receives enough sunshine.
Only water the Pachyphytum Oviferum in the container when the soil feels dry to a depth of 4 inches. Your delicate succulent will be harmed if you water it when the earth still feels damp.
The best approach to determine whether your succulent needs water is to look at your Pachyphytum Oviferum leaves. Your succulents don’t need water if they are firm and seem fat. On the other hand, water your plant’s leaves immediately if they feel soft and appear wrinkled.
