Succulents can withstand both heat and cold. A succulent can survive in temperatures as low as 40 degrees Fahrenheit, much like the desert, which can have chilly nights.
How cold must it be for the majority of succulents?
Because they are fickle plants, succulents shouldn’t be kept in temps so low. Succulents cannot survive in cold climates, so if you see the outside temperature lowering, take immediate action to save succulents from freezing.
It is unlikely that succulents will survive in temperatures below 40 degrees Fahrenheit. Succulents are susceptible to freezing and dying at temperatures between 30 and 40 degrees.
When it gets colder than forty degrees Fahrenheit, succulents should be brought inside. Learn how to take care of your succulent in cold weather, why 40 degrees is the point at which it can no longer survive, and what other temperatures are harmful to these plants by reading on.
Are succulents too cool for 50 degrees?
You might be curious about the lowest temperature at which succulents cannot survive when taking care of them. Warm, arid regions are where these plants are native. Nevertheless, while some succulents can endure colder temperatures, others cannot. What degree of cold is therefore too much for your succulent?
Any temperature below 50 degrees Fahrenheit is too chilly for succulents, which typically require temps between 50 and 80 degrees Fahrenheit. Depending on the species, a succulent’s lowest temperature tolerance varies.
How much heat can succulents stand?
I’m assuming you’re here because you reside in a very hot region, or perhaps it’s simply getting hotter there, and you’re concerned about your succulents.
I’ve had a lot of practice with heat and succulents. My succulents were outdoors during a summer when we experienced several days in a row with temperatures above 100. (unusual for Utah). This undoubtedly caused some harm.
In order to avoid making the same mistakes I did, keep your succulents cold enough throughout the hottest weeks of summer.
Succulents typically conjure images of desert vegetation in the minds of most people. Although it is true that cacti, which are succulents, flourish in the desert, not all succulents do.
The majority of succulents prefer a constant temperature of 60 to 90 degrees. There are a few more factors that affect how much heat succulents can withstand, and I’d want to highlight those for you.
Can succulents endure temperatures of 30 degrees?
Succulents can be difficult to cultivate outdoors in the winter in colder locations. There are still certain succulent plants that thrive in snowy conditions, despite the fact that they are generally known for preferring sunlight and not the other way around. Three of the most cold-hardy genera are Sempervivum, Hardy Sedum, and Hardy Opuntia, which can withstand subfreezing winter temperatures of -30F. Agave and rosularia are two other succulents with high cold tolerance.
How can I determine whether my succulent is too cold?
Whether a succulent is a soft or hard succulent determines what temperature it can withstand.
Anything warmer than 32 degrees F will be enjoyable for soft succulents. preferably over 40 degrees.
These plants cannot endure colder than freezing temperatures. Their hefty, thick leaves, which serve as water reservoirs, will freeze and destroy the plant.
Succulents that can withstand the cold can sustain -20 F. The best it can manage is a zone 4 to 5, and let me tell you, that is very impressive.
You must keep in mind that even if they can withstand temperatures below zero, they still like dry soil. That remains constant.
The majority of winters in the contiguous US will not only be dry but also wet and snowy.
Do succulents survive the cold outside?
There are many succulents that can endure the winter outside, even in extremely cold locations. These
Succulents that are hardy thrive in chilly, snowy winters. Sempervivum heuffelii, which maintains vivid colors for Winter Interest, is one of our favorites. The frost-hardy Sedum cultivars are especially recommended since they create excellent ground covers in practically all regions.
Succulents should be brought inside when?
Again, a lot of this depends on where you reside and what you’re growing. You should generally bring your succulents inside before the first frost. In the US, this occurs during the end of September for many people.
Naturally, if you are raising cold-tolerant succulents, they can spend the entire winter outside.
Knowing your local growth zone is crucial. You should at the very least be aware of your region’s typical low temperature. For instance, we were in Zone 5 when I lived in Utah. The majority of my succulents at the time were Zone 9 plants.
All succulents with a Zone rating higher than 5 must spend the winter indoors since they cannot withstand the cold.
Since I currently reside in a Zone 9 region near Phoenix, most of my succulent plants perform well year-round outside. Only a few succulents classified as Zone 10 or 11 will require spending the winter indoors.
Therefore, begin by classifying your succulents. Afterward, ascertain which growth zone you are in. Look how how the two contrast! Plants that are rated higher than where you reside should be brought inside.
You can use this video to decide whether you should bring your succulents indoors for the winter.
I have succulents, when should I cover them?
“Frost tender” succulents may experience variable degrees of damage, depending on how long the temperature is below freezing (32 degrees F). A sensitive plant’s cells expand, burst, and transform its leaves to mush when liquid inside them freezes. In a “light frost,” only the tips of the leaves may be harmed (“frost burn”). A “hard frost” is characterized by sustained temperatures below freezing, which can cause entire plants to die. Typically, succulents do not recover from roots.
Ones that are among the most fragile succulents include crassulas, aeoniums, euphorbias, and kalanchoes. Some succulents, in particular, have an inbuilt antifreeze that allows them to endure temperatures considerably below 32 degrees Fahrenheit—in fact, below zero.
Are your outdoor succulents at risk over the winter? Depending on where you reside, Please refer to “Cold Weather Care for Outdoor Succulents, By Region.”
Your area is frost-free (lucky you!) if…
This soft-leaved agave in my garden is the canary in the mineshaft when it comes to cold. Many succulents may survive a brief cold (less than an hour), but Agave attenuata’s leaf tips immediately reveal damage.
Although ugly, this damage rarely results in death. See how each leaf’s healthy green portion is? Cut each leaf to a point using scissors to remove the tissue-paper-like frozen tips. The harm won’t be very evident when you’re finished. Those shorter, clipped leaves will be buried by new growth during the summer. (Note: Such damage is comparable to scorching brought on by excessive sun and heat, which is common of desert conditions, and by wildfire, which, believe it or not, does occur.)
What about a succulent or agave that only suffers damage from frost on the tips of its leaves? Don’t even try trimming them. In a few months, it will shed those oldest leaves nevertheless.
areas with sporadic, light frosts (like Southern California’s interior):
If there is a “frost advisory” for your area, keep an eye on the weather forecast, and before it gets dark, go outdoors and cover your sensitive succulents. After midnight, frost is more common, and temperatures increase colder as dawn approaches. Warm air is lighter than cold air, which travels down hills and gathers in low areas. Succulents in swales are therefore more vulnerable than those on top of berms. You may have heard that Christmas lights slightly increase the temperature. Yes, if they are the traditional variety. LEDs in current use don’t produce heat. You should be concerned about succulents that are exposed to the elements and have nothing over them. I occasionally lean over a succulent and look up. It becomes draped if there aren’t any tree limbs or eaves directly above.
I reside at 1,500 feet in the foothills NE of San Diego (Zone 9b). And yes, after seeing the weather forecast on the late-night news, I have been outside at 11 p.m. in my pajamas and slippers, freezing while I place blankets on delicate plants while my husband holds a flashlight. I may leave the plants covered if several nights of frost are expected; otherwise, I take the sheets off the next morning. I fasten them with clothes pins and rocks to make sure they won’t blow off. AVOID using plastic. The plants are unable to breathe because of it.

Why cold damages some succulents and not others
The origin of a certain plant type affects it greatly. Most succulents are native to dry, hot areas where they can store water in their leaves to survive drought. The ones that don’t freeze, however, are from dry, cold climates. See my essay, Showy Succulents for Snowy Climates, in the Wall Street Journal. The “hardies” include:
several species and cultivars of sempervivums (hens-and-chicks, above); some cactus, yuccas, and agaves (such as Agave utahensis, A. montana, and A. parryi); and lewisias from the Pacific Northwest.
In the winter, should you cover succulents?
If you have a variety of succulents that can survive the winter outside, you might wish to do so. Your plump outdoor greens still require adequate care, though, otherwise the frost risked damaging them.
Not to mention that your plant’s roots could decay due to the winter’s damp soil. Additionally, if your region gets too much rain during the cold season, the succulents’ cells will swell. Additionally, the plant cell walls may rupture as a result of the frost. As a result, it is crucial to take precautions to safeguard your plant from all of these harmful situations.
Although some varieties of succulents can withstand below-freezing conditions, none of the species prefers frequent watering or excessive humidity throughout the year. Succulents prefer healthy soil that drains well, good airflow, and bright sunlight. Here are some precautions you should take to ensure your in-ground plants are taken care of over the winter.
Build a Greenhouse
The majority of succulents cannot withstand temperatures below 25 F during the winter nights. Bring your succulents into a DIY greenhouse if your area has the same winter temperatures, or if you have a gazebo, cover it with 5mm plastic and move your succulents there. Make sure to securely anchor the plastic, and tape the seams. You can even include a little heater if the temperature falls any lower.
Cover Your Succulents
Cover your outside succulent plants with bed sheets if your region occasionally suffers frost. Row covers and nonwoven fabrics, which are often constructed of spun nylon, are further options. Your plants will be protected when it is 2-4 degrees below freezing if you cover them with such blankets.
Additionally, don’t remove the dried leaves from your plants because they protect them from high temperatures. Move your plants that are sensitive to cold under a tree, deck, or eaves; this will prevent heat from escaping.
Can I leave my succulents outside?
Succulents are drought-tolerant plants because they can retain water in their large, irregularly shaped leaves. Succulents have a broad variety of eye-catching shapes and textures, which provide any landscape aesthetic interest. Can succulents live outside? is an often asked question. The quick response is “yes”! Growing succulents outdoors is an excellent alternative because they do well there and can withstand some neglect. They also do well in sunny areas with warm, dry weather.
Succulents can be grown in the ground, in pots, or hidden in unexpected planting locations. Take the uncertainty out of caring for these wonderful conversation pieces with stunning foliage by reading our suggestions for growing succulents outside.
Succulents can withstand the cold for how long?
Some succulents won’t even tolerate more than a couple of nights with a frost, as I’ve already explained. Not all succulents can withstand freezing conditions. This “tender” or “soft” group includes the majority of the more widespread succulent cultivars that you have probably heard of or seen.
You won’t be able to keep succulents outside through a winter with snow and ice, including Echeverias, Aeoniums, Haworthias, and the majority of Aloe species.
You can cover them with a frost cloth or other blanket if the freezing temperatures are only expected to last one or two nights, but this is not a long-term fix.
To find out what succulents are suitable for you outside, look up what growing zone you are in. Find out which succulents you have and what temperatures they are rated for after determining your growing zone.
Can succulents bounce back after a cold shock?
Cold fronts occasionally pass through, dropping temperatures toward freezing, even in regions with moderate winters. Most African succulent plants are vulnerable to cold. For instance, the University of Florida IFAS Extension notes that aloe vera (Aloe barbadensis) grows in USDA zones 9 through 11 while jade plant (Crassula argentea) grows in the frost-free regions of USDA zones 10 and 11. First to be harmed are delicate new growth or the thinnest plant portions, which typically seem fragile and discolored.
Even if your succulents freeze, all is not lost. If you suspect your succulent has frozen, Gardening Know How advises waiting a few weeks before evaluating and treating frost damage. The frozen plant should be recoverable if there is any fresh growth. Use a sharp knife dipped in rubbing alcohol to chop away the damaged areas of the plant, eliminating any tissue that appears squishy or has brown in it. This will help the plant to recover. Between cuts, clean the knife. Place container plants out of the direct light in a dry location. Resuming routine plant care after the wounds have healed
