How To Take Care Of Cactus Moon Grafted

These succulents will develop colourful 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 frequently should I water my grafted cactus moon?

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.


Moon cacti only require watering every two weeks (maybe even less in the winter), and the soil should totally dry out in between applications.

How is a grafted cactus maintained?

Cacti grafting is an excellent technique to add colour to your indoor plants or backyard garden. Although cacti require little care, there are a few things you can do to ensure that your plant is healthy:

  • 1. Offer some sunlight. Indirect light is the best for most grafted cacti. If you want to give your plants just enough sun without overheating them, try placing them on an east or west-facing windowsill.
  • 2. Refrain from overwetting. Desert plants like cacti don’t need as much water as other plants do. Once the earth is dry, you should only water your grafted cactus. To keep the scions of your grafted cactus vibrant, you can also spray the tops from time to time. Remember that different seasons may necessitate varying amounts of water—more in the summer, less in the winter.
  • 3. Calculate the soil’s pH. The ideal soil pH for your plant can be determined based on your rootstock. Numerous cacti favour well aerated, acidic to neutral soil.
  • 4. Give cactus fertiliser a try. Your grafted plant might grow healthily if you use the proper cactus fertiliser during the growing season.

How long do moon cacti with grafts live?

A grafted cactus with a brightly coloured 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 multicoloured 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, fertilise 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 colourful 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 utilise 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 utilises 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.

Where should moon cacti be planted?

The moon cactus requires the kind of temperature and amount of sunlight you might anticipate for a desert-type plant. They thrive in direct yet bright sunshine. Direct sunlight for extended periods of time can be damaging to plants. So the best place for a moon cactus is on a covered porch with some shade or somewhere where most of the direct sunlight is blocked. Although certain cacti species can withstand a winter freeze, it is best to move your moon cactus indoors or into the garage when the temperature dips below 40 degrees. If you are unable to protect them from the chilly weather, then cover them with a sheet or thin blanket. Keep in mind when the seasons change that cactus will freeze if left outside during a harsh winter.

Common Problems

Overwatering causes root rot, which is the biggest issue with moon cacti. The finest thing you can do is to take pleasure in your moon cactus’ steady growth and keep in mind not to overwater it. As long as you do not overwater them, they are often a beautiful, colourful, low-maintenance plant that is simple to manage.

Due to their very minimal maintenance needs, moon cacti are a great choice for newcomers in the plant world and a fun, easy, and colourful addition to your collection.

Does moon cactus grow well indoors?

Tamarind tree: According to legend, tamarind trees are sour, and if we plant one in our home, the joy there would likewise turn sour.

It is stated that growing date palm trees should be avoided to prevent poverty from entering the home. Additionally, those who raise this plant experience financial difficulties. Additionally, it has had a detrimental effect on health.

Bamboos are more than just an unusual and eye-catching plant. Bamboo is frequently grown by home owners as a rapidly expanding privacy screen around their property. However, it is not advisable to grow bamboo trees at home, according to Vastu. The planting of this plant at home will cause problems. The bamboo tree is employed in Hinduism as a sign of oblivion at the time of death.

Peepal Tree: People believe that growing a peepal tree at home will help us spread positivity because we have seen peepal trees in temples. However, it is suggested that a peepal tree never be planted in the house in accordance with Vastu Shastra. If you have a peepal tree at home, move it to a sacred location or plant it in a temple. This is supposed to be able to ruin your finances.

How long does it take a cactus transplant to recover?

Grafting is the science and method of joining two living plant fragments together so that they develop into a single plant. The plant will provide food for the seedling, promoting growth. Personally, I think it’s beautiful and makes me feel like I brought Frankenstein to life!

Here, you and I will study the methods for performing grafts so that your cactus will grow more quickly and reach maturity earlier than they would have otherwise.

When grafting, it typically takes 6 to 9 months to obtain mature plants, your cactus will begin to blossom, and it may even start producing fruits.

You don’t need to wait at least three to five years to obtain mature peyote because you can accomplish it with the Pereskiopsis in a matter of months.

The Pereskiopsis is a quick-growing rootstock and is the greatest approach to develop obstinate plants more quickly and safely than you would otherwise be able to. Here is where you may purchase pereskiopsis. It is here for the lophophora seeds.

I experimented with numerous methods in order to create the finest online instruction for grafting peyote cacti and other plants.

The following terms:

  • the plant you graft onto, in this case Pereskiopsis, is called a stock.
  • Scion
  • the seedling in this situation that you place on top of the stock

You will need the following items to get started:

  • a *sharp* scalpel Razor blades are still popular, but they are less prevalent than they once were. I never go without a sharp knife or cutter. After a cut, the blades need to be cleaned with alcohol (or similar). If you don’t have access to any of these items, I’ve also had success cleaning them by wrapping the blade in tin foil (to prevent soot) and lightly heating it with a lighter.
  • Pereskiopsis with roots. The stem should ideally be at least 10 cm (4 inches) tall, while shorter or higher stems can still be used.
  • For approximately 6-7 days, the grafts must be kept in a warm, humid environment in a clear plastic box or tent.
  • To handle the seedlings, use a pincette, tweezers, or something similar.
  • a clean area for the seedling operation, such as a plastic cover or something comparable
  • Although gloves are not required, it is better to wear them to protect yourself from the tiny spines.

Several crucial considerations MUST be made prior to beginning surgery:

  • aligning the vasculature rings. The vascular rings must overlap in some way, regardless of the scion/stock type, or your transplant will fail, as seen in the following example:
  • Since we’ll be working with little seedlings, it might be challenging to see the vascular rings. So simply place the seedlings on the stock slightly off-center.

Let’s begin our procedure now:

  • Slice off the Pereskiopsis’ top; you’ll typically reach the ideal diameter by cutting the plant’s top off at a length of about 1.5 cm (1/2 inch). To prevent the fungus, I used to clean my cutter with alcohol. You can assist yourself by holding a pincette, using it as a ruler to cut, and avoiding the pereskiopsis’s potentially harmful spikes. Ensure that the cut is simple! Removed the top two inches of leaves.
  • If the top of your pereskiopsis isn’t sufficiently moist, I also utilise some other methods. By halving the leaf, you can use it and squeeze the liquid to the top. The seedling should be hung on. (Wait a few minutes after you’ve attached your seedling before moving your graft to a wet location.)
  • Choose your preferred seedling and check that it is clean. Additionally, picking your seedling is crucial. I primarily took the little, two to four-week-old newborns. It can be younger or older. The size is the most critical factor. It must remain on the stock and not cross or leave the ring. If you’re doubtful, you should measure it to ensure that your stock’s diameter is more than that of your seedling (see picture below).
  • I often clean the seedling with water, lay it on a smooth surface, and slice it easily at the middle or bottom. If the seedling doesn’t attach to the cutter, it doesn’t matter; you can remove it with your fingers instead.

Transfer the seedling to the Pereskiopsis plant using a match, pincette (tweezers), or anything similar. Push the seedling gently from the top when it is slightly off-center on the stock to get rid of any potential air bubbles.

After grafting the seedling to the stock, the new joint should be placed as soon as possible in a humid environment. Spray some water on it after waiting five minutes. When you spray, try to avoid the seedling. For the typical fat-stock grafts, this is not necessary, but on Pereskiopsis, skipping this step ensures failure. The Pereskiopsis will shrink and reject the scion in dry air. I use a small greenhouse and regularly spray water within a vat of water to increase humidity (see picture below).

For about 7 days, the grafts must be kept in humidity. Though I have never experienced a fungus attack, this could cause worries.

Additionally, the Pereskiopsis top remnants that were cut off for the garft can be re-rooted. You will have new stock in a few weeks if you let it dry for a few hours and repot it in moist soil.

Place them outside (if you have enough sunlight or tropical weather as we do in Thailand) or under your growing lights after removing them from the chamber.

Depending on the species you grafted, it should start growing soon if the graft was successful. It may take a week before you see anything for some species. Some may require two to three weeks. The light green head and the separation’s heals are typically visible. the seedling will gradually expand.

Important: The pereskiopsis will frequently begin to send out new branches as you wait for the scion to begin growing. It is crucial that you cut these off (ideally with a sharp cutter or something similar, taking care not to damage the leaves), as otherwise the stock will focus its energy on expanding the new branches rather than strengthening the scion.

*CAUTION: I suggest that you immediately cut the tiny spine off of your hands or fingers. If it penetrates deeper into your skin, it may cause severe agony for a few days.
