Although the majority of people are familiar with the term “cactus,” there is another plant family called “euphorbia.” commonly known as “Euphorbia and spurge are frequently mistaken for cacti. Not your fault, that! Numerous nurseries market Euphorbia as a cactus, and these popular names are completely false. Using the pencil cactus as an illustration. In actuality, that plant is Euphorbia tirucalli. The baseball cactus, Euphorbia obesa, has a different name. Additionally, the plants themselves don’t help matters much. They may appear similar on the surface, yet both families contain plants with spines, branching limbs, and other like features.
They are undoubtedly related to each other, as you would have guessed. Not so. They are only superficially linked and share a similar appearance because of “When species that are not monophyletic or closely related independently develop similar traits as a result of needing to adapt to comparable habitats or ecological niches, this process is known as convergent evolution. In many regions of the world where there are protracted droughts, plants have developed comparable mechanisms to store water.
Succulents are a further source of confusion. Plants known as succulents store water in their leaves, stems, or both. All succulents are cacti, but not all cacti are succulents. However, euphorbia belong in the succulent plant family, along with agave, aloe, sedum, and hoya.
How do we determine whether we have a cactus or a euphorbia then? First of all, only in the Americas are cacti native. Except for a single species of mistletoe cactus, which is found in portions of Central America, the Caribbean, northern South America, Africa, and Asia, you won’t find any cactus in Africa, India, Europe, or Asia. The majority of euphorbia that resembles cactus originates in Africa and India.
While Euphorbia has a milky, sticky sap (latex) that is frequently hazardous, cacti typically have clear, aqueous sap. On an areole, cactus spines, which are modified leaves, grow in groups of more than two. The modified stems known as euphorbia spines grow in pairs and lack areoles.
Although they flower in quite different ways, cacti and euphorbias do. While Euphorbia blooms are frequently a pale greenish-yellow color and subtle, cactus blossoms are frequently huge and striking. However, there are certain Euphorbias with beautiful flowers, such as the widely distributed Euphorbia milli (crown of thorns) in Southwest Florida.
Currently, if someone says, “Check out the cactus I purchased! You can examine it more closely and perhaps respond.” It’s a Euphorbia, not a fern.

Am I losing my cactus?
A dying cactus may be unsteady in its potting soil and seem to be about to fall off.
In a severe case, it will undoubtedly fall off if you move it. showing a lack of roots Or the current ones might not be strong enough to adequately support the plant. Providing you potted the plant properly, that is.
Am I overwatering or underwatering my cactus?
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 for the summer, but do so gradually to give them time to get 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 plump and fleshy. The plant relies on these water reserves to live during dry spells. As the plant literally consumes its water reserves, the flesh will start to shrivel or pucker. As seen 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 use cactus or succulent soil that drains well, as your plants won’t want to stay in wet soil for very long. The leaves should quickly re-puff up!
too much From just a picture, it can 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, wet 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 small amount as opposed to completely soaking the soil.
The steps outlined above for identifying over-watering are the best way 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 can you tell whether your cactus is flourishing?
Everything is good if the cactus doesn’t visually alter. When cacti are not performing well, they alter their look. They fold up, collapse, go brown or mushy, or develop spots (yellow, brown, or black).
My cactus: Is it ill?
Openings in the flesh allow bacteria and fungi to enter the plant. The exposed sections may have been damaged by inanimate things, insects, or animals, or by severe weather, such hail. Injury’s physical manifestation is unimportant; what matters is fungal or bacterial damage.
Fungi and bacteria both produce more spores more quickly in warm, damp environments. When the organism establishes itself in your plant, the cactus will become mushy and soft. Small sunken places, discolored scabs, spherical soft areas encircled by fruiting bodies, and black or other colored specks on the cacti’s skin are signs to look out for. You might even see your cactus plants oozing a little bit.
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 I revive my dead cactus?
HOW TO SAVE A DIEING CACTUS AND RENEW YOUR PLANT
- REMOVE ROTTING COMPONENTS. Overwatering is typically indicated by rotting.
- CHANGE THE DAILY LIGHT.
- REVERSE WATERING.
- RINSE OFF DUST AND GREEN.
- PEST & INSECT CONTROL.
- FERTILIZE WITH LOW NITROGEN.
- ALLOW THEM TO DRY
- WATCH FOR DISCOLORATION & MUSHY SECTIONS.
What does a dried-up cactus resemble?
A cactus can suffer considerably more harm from overwatering than from underwatering. Most of the time, it ought to be fairly clear if the cactus has been overwatered.
Symptoms of cactus typically include the following:
- The stems and leaves of the cactus will begin to change color. typically dark or
- The cactus’ base will begin to turn brown or black.
- The cactus will start to rot and leak.
- It will begin to look as though the cactus is rotting or decomposing.
Root rot does not always become apparent right away. For a while, the outside of your plant could appear normal, but one day you might notice that the lower stem is turning black and becoming a little sticky. The news is quite horrible!
It’s interesting to note that a cactus that has received too much water may occasionally exhibit underwatering symptoms as a result of root rot killing the roots. Overwatered plants can actually get dehydrated because their roots will die and stop transferring water to the rest of the plant.
