How to Care for a Moon Cactus?

Known for their vibrant colors and relatively smaller size, moon cacti are native to many South American deserts. Unlike other cacti, these indoor plants can also bloom colored flowers. Wondering how to care for a moon cactus and get the best out of its vibrant appearance? Here’s a brief yet detailed guide to help you get started.

What Is a Moon Cactus?

Native to deserts in Paraguay, Argentina, and Brazil, the moon cactus is a Cactaceae family member. Also known as the red cap and ruby ball cactus, the moon cactus is about two inches wide. Furthermore, it has sharp, small spines.

Since these plants do not produce chlorophyll, they bloom a range of colors from neon yellow to hot pink. While the lack of chlorophyll poses a threat to its survival, it is possible to graft the plant with dragon fruit. Additionally, you can also merge it with green cacti of various species.

The key factor to note is that these plants struggle to survive on their own. In fact, under minimal care, they may not survive for more than a few months.

Keep It Indoors

The top part of a moon cactus cannot tolerate sunlight. Hence, keeping it indoors is your best bet to ensure the plant lasts long.

Understanding how to care for a moon cactus begins with understanding its sunlight needs. All it can tolerate is an hour or two in bright shade. However, if you live in a region with intense sunlight, the cactus may be prone to sunburn.

On the other hand, exposing it to intense cold weather may also not be wise. Moon cacti need adequate protection from frost.

Don’t Water It Too Much

When it comes to their water needs, moon cacti don’t require much. Compared to other types of cacti, it isn’t the thirstiest.

So, you want to limit watering it to once every two weeks. This way, you’ll help the soil dry properly. Furthermore, you want to limit the watering spree even more in winter.

The most important aspect of watering your moon cactus is ensuring that there isn’t moisture build-up. One way to prevent it is by placing it in a pot that has holes for drainage.

Propagate It Right

Propagating a plant refers to breeding its specimens through organic processes from the parent stock. In the case of a moon cactus, the colorful part often produces small offshoots.

You can graft these offshoots onto another cactus by cutting the top pieces neatly. Then, you can place the offshoot on top of this new rootstock. Use a string or rubber band to hold them in place. In about six weeks, you will notice the plants growing together. However, keep an eye out for pests or rot.

Use the Right Soil

Another aspect to look into when wondering how to care for a moon cactus is the soil. Moon cactus thrives in a soil mix that drains well.

The pot you’ve placed it in should have enough drainage holes to prevent root rot. Hence, professionals often recommend adding perlite or coarse sand to the soil mix.

Don’t Fertilize It Too Much

Cacti don’t usually require daily feeds. However, you can fertilize them during the growing season and stop when they get dormant during the winter season.

Report It When Needed

The moon cactus hardly ever outgrows its container. Hence, the only time you should consider repotting it is when you bring it home. The right way to repot it is by taking adequate safety measures such as wearing gloves. Before removing it completely from the pot, ensure that it’s dry.

Additionally, you also want to remove the oil soil and any dead roots in it. The fresh soil in a new pot will not require watering right away. Allow the new roots to settle before you begin watering them.

What Problems Should You Look Out For?

When determining how to care for a moon cactus, make sure to find some common problems to look out for. For instance, root rot is one of the most common problems for cacti plants. Often a result of overwatering, it can cause the plant to wither and hinder its growth in many areas.

Allow the plant to grow slowly and bloom in a healthy environment. The plant is not only low maintenance but also easy to grow.

Another common problem to look out for is beige spots. Since moon cacti are sensitive to light, they can be exposed to sunburn. This results in beige patches.

Hence, you want to move the plant to a place with less light as soon as you notice them. Corking is another one to look out for.

While corking is natural in an aging moon cactus, it may not be pleasant to look at. It appears as a solid bark texture that commences from the base of the plant. While it isn’t dangerous, it may result in other problems later on.

Sometimes, the symptoms of corking are similar to the symptoms of rotting. So, make sure to touch the plant before reaching a conclusion. If the affected part is firm, it is most likely due to corking. If it is soft or mushy, it is likely due to rotting.

While you’re at it, remember to keep an eye on the pests. Bugs are easily attracted to a freshly propagated plant. The best way to keep this danger at bay is to use a neem oil spray in time.

Speaking of pests, fungal diseases are also serious hazards that first appear as brown spots. Once the infestation has taken place, it may be very hard to control.

The damage that starts as brown spots soon enlarge and promotes the growth of diseases. All in all, extremely low lighting, high humidity, and overwatering can result in serious problems later on.

How to Care For a Moon Cactus: Tips to Solve Brown Spots

While brown spots do not always indicate a serious problem, they often require immediate attention. Here are some ways to prevent further damage from taking place.

Move It Away From the Source of Damage Immediately

The best way to avoid further burns is to move your moon cactus away from bright sunlight right away. Another way to determine whether your plant is getting scorched is by looking out for any changes in the color. If you notice your moon cactus losing its color, it may be a sign of sunburn.

Use an Effective Fungicide

Fungi can be extremely difficult to remove. The only way to get rid of them is by applying an effective fungicide. Fungus infections, if not taken care of in time, can cause the plant to die. They may even spread to other plants nearby. In this case, you want to isolate the plant and disinfect the spot right away.
