Who doesn’t enjoy improving their space’s aesthetics? Grafted cactus is a lovely, low-maintenance plant that is ideal for revitalizing your landscape. Even if you are just starting out, you can transplant a cactus. Continue reading for a detailed explanation of grafted cactus, along with a method and maintenance manual.
What is a Grafted Cactus?
When two distinct cactus species are grafted together to create a single plant, the result is a grafted cactus. The majority of people frequently mistake these plants for flowers when they view their beautiful tops. Few people are aware that they are actually grafted cacti, though. It’s interesting to notice that the cactus at the top is known as the “Scion.” These mutant forms of common cactus are lovely and vibrant. On the other hand, the green bottom cactus is referred to as the “Rootstock.” Mutant pups are grafted on rootstock plants, giving the cactus plant a completely different look. A fully grown grafted cactus can grow up to 2 to 3 inches tall, giving them a little and compact appearance.
Why to Graft a Cactus?
For a variety of reasons, grafting is carried out. The mutant pups can occasionally separate from their mother plant. They consequently perish as a result of the absence of chlorophyll. Grafting is carried out to aid in their survival. By affixing them to rootstock plants, they receive all the nutrients they require and can flourish. Another factor is their strikingly unique appearance, which elevates them to the status of a must-have yard or living room showstopper.
Best Season for Grafting Cactus
The best time to graft a cactus is during the growing season for effective results. The optimum time to complete the process is in the spring or summer. Avoid grafting when the trees are dormant in the winter. Once finished, provide minimum watering and indirect sunlight for your small plant.
How to Graft Cactus?
Not only is grafting a cactus a doable task, but it also stimulates your creative side. It is preferable to begin with a little, easily handled cactus if you are a novice gardener.
Cactus can be grafted in four different ways:
- Flat or Lateral Graft
- The Side Stitch
- Cleft Grafting
- Statistical Graft
The scion is positioned differently in each of the aforementioned methods. The Lateral Graft is the simplest and most efficient procedure.
Steps involved in grafting:
- Apply a clean, sterile knife or blade to the rootstock plant and first chop off the top. A minimum of two to three inches above the soil should be removed. Additionally, the wound needs to be tidy and unbroken.
- Take a second cactus that you wish to transplant on top of the first one now. To make a scion, choose a healthy section of the cactus and cut it off. To make it easier to position the scion and rootstock, make sure the cut portions of each have similar diameters.
- To help the scion and your rootstock plant bind together, place it on top of the wound. The vascular cambium is the site of contact where the cuts of the two species collide.
- Rubber bands should be used to join the pieces together from top to bottom and even on the pot’s sides.
- You can see the scion begin to grow in about two weeks. The rubber bands can be taken off at this point because the two species have merged into a single tiny plant.
Light Requirements
Full direct sunlight is not preferred by grafted cacti. Instead, it functions best when exposed to strong indirect light. Therefore, when grown outdoors, remember to place your grafted plant in a location that receives some partial shade. It is best to place indoor plants close to a window.
Watering
For grafted cactus, avoiding overwatering is essential. These plants can withstand drought and require minimal upkeep to flourish. You might also spritz them now and again with a spray bottle. Once the soil has dried up and any extra moisture has been drained, water the plants. While less or no irrigation is needed in the winter, more watering is needed in the summer.
Soil & Fertilizer
Your grafted cactus can thrive in a quick-draining soil mixture. Additionally, most plants prefer acidic to neutral soil. During the plant’s active growing season, fertilize it with cactus fertilizer. Do not, however, feed them while they are dormant.
Frost Tolerance
Your grafted cacti’s rootstock is vulnerable to frost. Therefore, it is preferable to bring them inside where the ideal temperature is 15 C if you reside in a region that gets colder throughout specific months.
What purpose does it serve to graft cacti?
There are several reasons why cacti are grafted. One goal may be to mechanically create a new species, but other benefits include the production of disease-free stems, the replacement of rotting stems with new ones, and the improvement of photosynthesis in plants that are incapable of it. Cactus plants can take on unusual shapes, including weeping plants, through the process of grafting.
Grafting is frequently used on fruiting plants since it raises an existing cultivar’s maturity for early fruit production. The scion develops into the top portion of the plant with all the traits of the parent species. The roots and base of the plant are formed by the rootstock. The vascular cambium, where the wounds of the scion and rootstock are bound together to heal, is where the union occurs.
There is no particular care needed for grafted cactus once the connection wounds have healed. Simply take care of it like any other plant.
Rootstock Cactus for Grafting
The following rootstocks are commonly accepted for grafting cacti:
- Hylocereus undatus or trigonus
- Peruvian Cereus
- Spachian trichocereus
Additionally, there is excellent compatibility if the rootstock and scion belong to the same species. As the family connection deteriorates, compatibility declines. Although it is possible for two plants from the same genus to graft together, it is extremely uncommon for two plants from the same family to do so. For the greatest results, grafting should only be done on cacti that are of the same species and have a tight genetic tie.
How to Graft Cactus
When making cuts, use only sterile, extremely clean equipment. Make a scion from healthy plants you’ve chosen. Trim the stem to a minimum of 1 inch (2.5 cm) from the top. Beheading a cactus to a few inches (7.5 cm) of the earth will then prepare the rootstock.
Place the scion such that both vascular cambium are next to the cut section of the still-rooted rootstock. Rubber bands can be used to keep the components together.
Care for grafted and ungrafted cacti is the same. Keep an eye out for any rot or insects at the union. The union should be sealed by the time the rubber bands are removed, which should take about two months.
Do cactus with grafts grow?
A home or yard with a brilliant moon cactus (ruby ball cactus) will look lovely.
In the wild, the vibrant cactus tops that you can buy in many stores aren’t as noticeable. Argentina and Paraguay are the native home of this tiny cactus plant. The vivid hues of red, pink, yellow, and orange are entirely organic.
Mutant Gymnocalycium mihanovichii plants that lack chlorophyll—the pigment that gives plants their green color—develop these neon-bright hues. But all other plant species would perish without chlorophyll. So the spherical cactus is grafted onto a conventional cactus to keep the cactus alive.
Any species of cactus can be used to make a vibrant moon cactus (Hibotan). The Hylocereus cactus species is typically used as the stock for moon cacti that are sold in garden centers. These green cactus have straight stems with a cross-sectional shape like a star. Perhaps the star-flower cactus’ name derives from the curvature of its stem. The ruby ball cactus may be grafted onto the top perfectly due to the form.
The vibrant cactus top receives nutrition from the stem cactus at the bottom. So long as you give your plant the attention it needs, the grafted cactus will prosper.
How should a grafted cactus be cared for?
Cacti grafting is an excellent technique to add color 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 favor well aerated, acidic to neutral soil.
- 4. Give cactus fertilizer a try. Your grafted plant might grow healthily if you use the proper cactus fertilizer during the growing season.
How old are grafted cacti?
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.
How often should a grafted 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.

How should a grafted cactus be replanted?
Modifying the Soil Repotting a moon cactus typically entails replacing the soil in the pot. Your moon cactus needs new, fresh soil to grow and be healthy because older soil has fewer nutrients to offer. When filling a fresh container for the cactus, you can either use a pre-made cactus mix from the store or a combination of peat soil and coarse sand. Prior to repotting the cactus into this mixture, lightly wet it.
Getting Ready to Repot the Cactus Make sure to hydrate the moon cactus several days before you intend to repot it so that the roots are moderately moisturized. Carefully remove the plant from its pot when you’re ready to transport it. Gently set it into the new pot, then fill in the spaces with the soil of your choice. Be sure to leave room at the top of the pot so the cactus can be watered. Perhaps you should strew some sand on top of the new container. For about a week, the new cactus shouldn’t be watered.
You have it now! Your moon cactus has been replanted and should remain healthy for the next three to four years.
Do grafted cacti grow more quickly?
It is a seedling of the unusual, leafy Pereskiopsis spathulata cactus, which I previously talked about, and the magnificent hardy cactus Echinocereus reichenbachii.
Why do this? Besides the fact that it’s very cool, what else? Because the grafted cactus receives a lot of energy from the robust, quick-growing rootstock, it grows much more quickly than if it were left to grow on its own roots.
Here is a (bad, fuzzy) photo of the graft as it appeared when I initially created it in July. It has expanded greatly in just three months, whereas the seedlings I left on their own roots essentially have the same appearance. After letting it develop on the graft for a while, I’ll likely take it off and place it into the garden sometime next year. This will allow me to have a respectably large plant in a reasonable length of time.
So, try grafting a pokey cactus if you want to hasten its growth. The procedure is quite simple, a lot of fun, and is explained in great detail here.
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.
