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.

Do grafted cacti need watering?
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.
How much sunlight is required for grafted cacti?
The stock green cacti at the bottom, on the other hand, frequently enjoy light. The optimal conditions for these cacti are areas with brilliant indirect light and only a few hours of morning sunlight. The colors will fade if there is too much direct sunlight.
How is a grafted cactus maintained?
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.
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 colorful 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 utilize 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 utilizes 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.
What is the lifespan of grafted cacti?
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.
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.
