Unbelievably, if your cactus is placed in front of a hot window, it may receive too much light.
The development of brown spots on the tips of your cactus may be an indication of sunburn.
Your cactus is showing signs of sun stress, which is readily remedied by relocating it to an area with less direct sunshine.
Should I remove the brown cactus parts?
When a cactus begins to rot, all of the rot needs to be removed in order to salvage the plant. If it is not entirely eliminated, it will spread and finally kill your cactus. Additionally, cactus rot spreads swiftly.
You must move quickly if you don’t want to wind up with a dead cactus plant.
What needs to be done to save your cactus depends on where the decay is occurring. Therefore, I’ll start by demonstrating how to rescue a cactus that is rotting top down.
I’ll then discuss how to salvage a cactus that is rotting from the bottom up in the part that follows.
How To Save A Cactus Rotting Top Down
Cactus tip rot might give false hope. If you see a few little brown spots on a cactus, you can mistake them for minor rot.
Then, as you work to eliminate the troublesome areas, you come to the conclusion that the interior is actually much, much worse than the exterior.
So, before you begin chopping, take a moment to mentally get ready for what you might discover. Ready? Okay, follow these instructions to get rid of cactus stem rot.
Step 1: Select your pruning instrument.
To get rid of the rot, use a sharp knife or pruning shears. I advise using a sharp knife if your cactus is particularly thick.
Otherwise, precision pruners or bonsai shears would be excellent for little plants with thin stems. Just make sure they’re razor sharp to prevent crushing the cactus stem.
Clean your cutting instrument in Step 2—do not omit this step!
Before making any incisions, it is crucial that the equipment you select to use is sterile and thoroughly clean.
It will be easier to stop the spread of illness and fungus spores if you use a clean pruning instrument. You only need to clean your pruning shears or knife with soap and water before drying it off and beginning.
Additionally, I advise cleaning and drying it once more in between each cut. To disinfect it, you might also dip it in rubbing alcohol.
Step 3: Layerarily remove the cactus stem rot
To ensure that all of the rot has been eliminated, it is advisable to trim off the affected areas in stages.
You can see that my cactus plant’s middle, despite appearing to be healthy, nevertheless has interior rot. Consequently, we must continue.
Step 4: Continue stripping away layers until no rot is visible.
The rot will become thinner and thinner as you remove plant layers one by one.
But keep in mind that even a small amount of rot can spread. Therefore, until there are no longer any indications of rot on the plant, be sure to remove all indications of brown, squishy, and mushy cactus material.
Make the last cut on your cactus at an angle if it’s an outside plant to prevent water from pooling on top of the wound (which will likely just cause it to rot again).
If at all feasible, I would also relocate the plant to a dry location shielded from the elements until the wound had calloused over.
Unfortunately, before I realized that the top of my plant was going brown, the rot was already rather bad. To completely remove the cactus, I had to cut off more than half of it.
Even though it was challenging for me to cut this cactus in half, I know that if I had left any rot behind, my plant would have died within a few weeks.
Cactus Care Tips After Pruning
If you have to operate on one of your favorite plants, be sure to watch it closely afterward to make sure it doesn’t continue to decay. If it starts to decay once more, eliminate the new rot by following the same instructions as before.
The wound should callus over within a few days, and your cactus will eventually send out new growth close to the cut.
I hated having to chop my cactus in half to get rid of the rot. However, in the end, I believe it gave the plant more personality.
How To Save A Cactus Rotting Bottom Up
Unfortunately, there isn’t much you can do to salvage a cactus that is decaying from the ground up or has damaged roots.
In this situation, cutting healthy stem sections off and replanting the cuttings is the best course of action.
To ensure that all of the rot is removed from the cuttings, prune your cactus back in layers as instructed in the steps above. Till the cut end has callused over, let the cutting dry for a few days.
Wait to irrigate the soil until the cutting has new growth. Cactus cuttings can take several weeks to root, depending on the kind you have.
How can you tell if you’re watering your cactus too much?
Here are a few frequent problems that many plant owners have when trying to determine the best approach to take care of succulents and cacti.
Cacti and succulents adore light. No succulent or cactus we’ve ever seen wants to sit on your gloomy office desk, even if some species (for succulents, try haworthia or gasteria; for cacti, try epiphytes like rhipsalis and hatiora) can endure lower light. To thrive, these guys need to be close to a window, ideally one that faces south so they can make the most of the sunlight. The first step in determining whether you are prepared to care for succulents and cacti is to choose a light spot in your home.
When they don’t receive enough light, succulents exhibit peculiar behavior. If your succulents require more light, you’ll frequently notice yellowing in them. Bright pink, purple, or yellow colors frequently return to simply plain green, while deep green will eventually fade to pale green.
The development habits of succulents are similarly impacted by inadequate light. Succulents frequently become long and spindly in an effort to reach for the light. Sempervivum and echeveria species, which typically grow in rosettes, may suddenly start growing tall and reaching for additional light.
Likewise with cacti. As the cactus strives for light, what was formerly dark, robust flesh may turn pale. Additionally, just like “reaching succulents,” cacti that don’t get enough light will exhibit odd growth patterns. Etiolation is the process of new growth being significantly smaller than the rest of the plant; occasionally, long, tendril-like branches or unusually skinny new growth on the top of the cactus will emerge.
Succulents and cacti can bounce back from too little light, but the etiolated growth habit is irreversible. If the strange growth pattern bothers you, consider trimming it off. Many succulents and cacti may flourish after pruning. The new growth that appears should be “normal and non-etiolated” as long as you relocate your plant to a position where it will receive enough light.
Finally, because the soil will remain wet for too long in the absence of proper light, root rot might also result. See if your plant might be experiencing root rot as a result of inadequate light by seeing the photographs of it below.
Most cacti and succulents can withstand direct sunlight. However, if your plant isn’t used to it, using too much can be hazardous. For instance, moving a succulent or cactus onto the porch for the summer (very recommended!) and suddenly exposing it to 3 or 4 hours of direct sunlight per day will cause it to burn.
Burn typically manifests itself on your cactus and succulents as browned or calloused flesh. Your best approach for recognizing burn is to look for discoloration, especially on the side of the plant facing the window. A coarser texture will develop on the burned leaves or meat compared to the remainder of the plant.
Burnt leaves cannot be repaired; you can either remove them by pruning or by changing the surroundings so that your plant receives more suitable light.
Succulents and cacti should be moved outdoors during the summer, but do it gradually to give them time to become used to the brighter environment. Start them off in a shaded outdoor space (which will still be brighter than your living room, most likely), and gradually increase their exposure to light over the course of a week or two.
not enough It is undoubtedly safer to provide too little water than too much in the context of caring for succulents and cacti. Despite this, succulents and cacti do require water, particularly in the spring and summer when they are actively growing.
The problematic issue is that having too much or too little water can sometimes appear alike. However, if you err on the side of caution, you might reasonably assume that you are under-watering if your plant exhibits the following behaviors.
When succulents receive insufficient water, they frequently pucker. Because they store water in their foliage, succulents and cacti are lush and meaty. The plant relies on these water reserves to live during dry spells. As the plant physically consumes its water stores, the flesh will start to shrivel or pucker. As observed in these jade species, this typically begins on the lower leaves and moves its way up the plant:
Here’s another illustration of a succulent that is thirsty (a few of which often happen to be etiolated from low light). Observe how they seem a little bit shriveled:
Additionally, a dry cactus may pucker or shrivel in addition to discoloring (usually getting brown and dry, or calloused).
Give your cactus and succulents a nice, thorough watering if they exhibit these symptoms. But always choose cactus or succulent soil that drains properly, as your plants won’t want to stay in wet soil for very long. The leaves should quickly re-puff up!
too much From only a picture, it might be difficult to tell whether a cactus has received too much or too little water. Without knowing how much water it received, for instance, it would be difficult to determine whether this opuntia cactus received too much or not because the symptoms are frequently similar:
However, a succulent or cactus that has received too much water will feel mushy rather than simply puckered. These plants can store a lot of water, but once that storage capacity is exhausted, the plant will literally come apart as the cell walls and roots decay. This results in them becoming mushy, and it’s a crucial distinction that may help you distinguish between over- and under-watering while also looking at your own watering practices and the surrounding environment.
Overwatering is characterized by a variety of symptoms, including browning or blackening of the plant’s leaves or stems, browning or blackening at the plant’s base, mushy or leaky plants, and plants that are practically decomposing in front of your eyes.
Gently remove your succulent or cactus from its pot and look at the roots if you suspect decay. When a plant has brown or black roots, it
To cool Because they are native to desert settings, the majority of succulents and cacti are well-suited to freezing nighttime temperatures (jungle cacti, for example). Most succulents and cacti prefer chilly nights, especially in the winter. In fact, several species, such jade, christmas cactus, and epiphylum, bloom more readily in colder climates.
Low temperatures, however, can be an issue indoors because they frequently coincide with high humidity levels. When you water your cacti and succulents in the cool winter months, the soil will remain moist for a lot longer than it would in the hot summer months. You guessed it: root rot results from cool, damp soil.
Pay close attention to your succulent and cactus watering schedule if your house gets quite cold in the winter. You might only need to water your plants once a month or even less, depending on their type, size, drainage capabilities, and pot. Additionally, we advise erring on the side of caution when it comes to winter watering and giving the plant a moderate amount as opposed to completely soaking the soil.
The procedures outlined above for identifying over-watering are the best approach to determine if too-cold temperatures are having an impact on your succulents and cacti.
too warm Cacti and succulents are particularly skilled at tolerating high temperatures since they can survive cold temperatures for the same reason! After all, the desert is a region of extremes.
However, excessive heat in an indoor growth setting frequently causes watering problems. If your plants are outdoors in the heat, they will quickly dry out. Depending on the heat and exposure, you might need to water your succulents and cacti twice a month or even every week.
When put in a window, excessive temperatures can also be a problem for cacti and succulents. Plants can be burned by the sun’s heat coming through glass since it tends to be more intense. Utilizing the detection procedures outlined under “too much light,” check for burn.

How frequently ought I to water my cactus?
The most frequent reason for cacti failure is improper watering, whether it is done too much or too little. Cacti have evolved to store water for extended periods of time and can maintain moisture through droughts because they are endemic to arid regions and dry temperatures. They have a limited capacity, which is why over-watering can result in a variety of issues.
When it comes to regularity, watering your cacti will largely depend on the season but also on the variety. Checking the soil is the easiest technique to determine whether your cactus needs water: It’s time for a drink if the top inch is dry. That entails applying the “soak and dry procedure” on cactus.
What is the soak and dry method?
The soak and dry technique is thoroughly wetting the soil until part of it begins to flow out the drainage hole, then waiting until the mixture is nearly dry before wetting it once more. If done properly, this strategy will help them endure a period of under-watering should you need to travel or leave the house because it takes use of their natural tendency to store water (or if you just get busy and watering falls to the wayside, as happens to all of us now and again).
Watering during the growing season versus the inactive season
Like with many houseplants, the season affects how frequently you need water. It becomes more crucial that you get in the habit of examining the soil to determine whether your cacti are thirsty. A healthy cactus needs watering every one to two weeks during the growing season, according to general wisdom. The frequency changes to once every three to four weeks during the off-season.
Even then, it’s crucial to examine the soil. The same way that not all interior spaces and not all cacti are alike. The only way to be certain that your cactus require watering is to carefully examine the soil to determine how dry it is because there are so many different factors.
