Why Is My Moon Cactus Turning Brown

The stem is frequently rotting if it begins to turn brown. A strong, green stem is a sign of health. The most frequent reason for a cactus plant’s brown, rotting stem is root rot, which is nearly always caused by either overwatering, inadequate drainage, or both. Sadly, this can spell doom for your moon cactus. The plant won’t be able to recover if the roots are killed, however you can simply check this. Examine the roots by gently removing the plant from the pot or digging it out. The plant is likely dead if they are slimy and brown. If they are white and firm, consider replanting the cactus in a fresh pot or garden spot with new, sterile soil.

How can a dying moon cactus be revived?

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.

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.

Can a brown cactus be revived?

Cactus death is typically caused by root rot brought on by over watering and poorly draining potting soils. Between waterings, cacti require the soil surrounding their roots to dry out. The cactus turns yellow, brown, or black with a spongy texture if the soil is persistently moist.

If a cactus receives too much shade, the stem will droop or lean over, but if it is shifted from shade to full sun without first being exposed to more intense light, the cactus will turn white and appear burnt.

When a cactus is living in conditions that are drastically different from those of its natural environment, it will eventually die.

By placing the cactus in at least six hours of direct sunlight, only watering when the soil has completely dried out, and planting or repotting the cactus in specially formulated well-draining gritty succulent and cacti soil to improve drainage so the cactus can recover, you can revive a dying cactus.

How can I care for a cactus that is becoming brown?

Look to check if the brown spot and the vicinity are mushy and soft. If so, your cactus has probably started to rot from the inside out and is now displaying symptoms on the outside.

After noticing soft brown areas, the best technique to fix your cactus is to cut off healthy stems (without any signs of rot) and start a new plant.

Before cutting, disinfect a razor blade or a pair of extremely sharp sheers. Cut the cactus above the area of rot, allow it to dry, callus over, and then plant it again.

Use fresh soil, and thoroughly clean and dry the pot if you’re using the same one. Unfortunately, there isn’t much you can do to save your cactus as is once it has begun to decay.

In other words, the only method to revive a cactus that has developed rot is to cut off the healthy stems—those portions of the plant that are still green—and repot them in fresh soil.

A moon cactus needs how much water?

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.

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.

How should a moon cactus be cared for?

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, colorful, 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 colorful addition to your collection.

What kind of plant are overwatered cactus?

The obvious indicators of an overwatered cactus caused by a fungus in the soil include black or brown blotches and mushy stems. It’s time to carefully chop them off with a knife if you experience any of these bodily symptoms. Use a sterilized knife while handling a rotting plant to prevent the spread of the infection.

You will have to exert more effort if the damage is severe. Essentially, what you’ll be doing is multiplying the portions of your plant that are still alive. Wear nitrile gloves to protect your hands from the cactus’ spines while you chop off the rotting sections, and exercise extreme caution when handling the plant. After cutting out the damaged areas, let your cuttings air dry for a few days, or around a week.

What does a cactus that is dying look like?

Possible dead cactus symptoms include: Cacti topple over or are exceedingly flimsy in the ground. Spikes could come off. These two symptoms point to both root rot and overwatering. Yellow turns brown in color.

How can you determine if a cactus has been overwatered or not?

The cactus won’t typically seem radically different from day to day because underwatering typically happens gradually over time.

There are a few indicators, nevertheless, that will let you know if your cactus is submerged.

Signs of an Underwatered Cactus

Knowing the warning signals of an underwatered cactus is crucial for prompt response. Your cactus will have a better chance of recovering if you do this.

The most typical warning indicators of a submerged cactus include:

The Cactus Is Light Green or Yellowish

Since this normally happens gradually over time, the color change might not be apparent right away.

If your cactus begin to become light green or yellowish, keep an eye out for more symptoms of an underwatered plant.

The Spines Are Falling off Easily

A well-watered cactus has roots that go far into the ground and take in water there.

Their root systems do not, however, work correctly while they are underwater because the dearth of nutrients in the soil leads them to wither away.

As a result, the spines become fragile and easily detach.

another typical indicator of a submerged cactus

The Cactus Is Wilting

Due to nutrient deficiency, their spines cannot support the plant adequately, which causes them to lose their shape.

As a result, plants that were formerly upright and in good shape gradually start to sag or droop.

Decay at the Base of the Plant

Roots will cease developing and begin to deteriorate over time if they are unable to absorb enough nutrients from the soil as a result of a lack of water, which will eventually result in decay at the base of the plant.

It’s possible that you won’t immediately notice whether or not your cacti are underwater because this normally happens gradually.

The New Growth on Your Cacti Is Weak and off Center With Older Growth

Lack of nutrients will have an impact on how a cactus develops new limbs.

In this instance, you’ll see that the younger growth is somewhat deformed and less symmetrical than the older ones-another indication that the cactus has been submerged.
