Yes, it is the answer. Although certain succulents can withstand frost, they are frequently thought of as drought-tolerant plants. They flourish in chilly, snowy conditions, and the extreme cold even brings out their magnificent, vivid colors. They are referred to as “Hard Succulents.” Sempervivum, Sedum, and Euphorbias genera contain some of the most hardy succulents. You may plant such succulents outside all year round because the majority of them can withstand temperatures as low as -20F (Hardiness Zone 5).
“Soft Succulents” are another group of succulents that are more susceptible to frost. When the weather drops below freezing, they must be winterized inside.
Outside, how cold is too cold for 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.
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.
How should succulents be cared for during the winter?
The type of succulent you have will determine how to care for it in the fall and winter. They are, on the whole, a group that is simple to develop. If you provide them some sand, some water, and sunlight, they will repay you with beautiful shapes, cleaner air, and comforting company. But it helps to know how to handle a variety of these delicate guests and make them feel completely at home, whether you’re welcoming them inside over the winter or prolonging their stay as houseplants!
Know Your Succulents
With over 6,000 distinct varieties of succulents in 60 different plant families, it’s critical to understand which particular succulent you are taking care of. Knowing if your succulents are indoor growers or cold hardy succulents is important when talking about winter. The majority are from distant, scorching desert locations, but we do have a few that can withstand our zone 5 temperature. Some varieties of Sedums and Sempervivums, among others, may weather the harsh winters in the Chicago area, but many traditional succulents, such as Aloe Vera, Jade Plants, Panda Plants, and Christmas Cactus, must be kept warm and sheltered indoors.
Bringing Succulents Indoors
Before it gets below freezing, you must bring all of your sensitive, non-cold-hardy succulents indoors. Check for bugs and get rid of any ants, spiders, or other small creatures you find if you’re keeping them in the same pot. Additionally, remove any debris from the soil’s surface, such as dead leaves and twigs. Over the winter, you should offer your succulents a clean place to dwell and keep them away from any rotting objects.
Fall and Winter Maintenance
Succulents typically grow in dry, arid areas. They can store water for a long time thanks to their hefty, luscious leaves. This distinguishing characteristic lends them their distinct beauty, but properly caring for them still necessitates a few skills.
Repotting: You might want to do this if you’re bringing your succulents indoors. They could possibly use some fresh soil or a smaller container that will fit next to your window. Sandy, well-draining soil will help these desert plants flourish. Choose a particular succulent or cactus mix instead of a potting mixture that maintains moisture. Give them a container with lots of drainage holes, and take special care not to hurt their fragile roots when moving them.
Sunlight: Succulents are native to a variety of locations worldwide. Many originated in dry, fully-lit locations, while others developed in the cover of a jungle canopy. Find out whether your plants like direct or indirect sunlight by speaking with the gardening specialists at our garden centers or researching them online. Check on your guests sometimes to make sure they are not becoming sunburned because glass can sometimes enhance the strength of the sunshine. However, if you notice them slanting toward the window, it can indicate that they aren’t getting enough light.
Water: Many overzealous plant enthusiasts drown their succulents here. They are unaware that maintaining their dryness is just as crucial as moistening them. Between waterings, the top inch of the soil should be absolutely dry. When you do water them, give them a drenching similar to a desert downpour before cutting them off until their next need. Keep in mind that you should water the soil and not the leaves, which could decay. If the foliage is mushy, discolored, or squishy, you’re providing them with too many refreshments.
Navigating Winter Dormancy
Succulents spend a portion of the year inactive, like the majority of plants. This is a component of their coping strategy during a tough or dry season. Some plants hibernate over the winter, including your hardy sedums, agave plants, and pincushion cacti. They need considerably less water at this time. Frequently, watering once every two weeks is adequate.
Since many of them are native to the desert, they really hibernate during the hot, dry summers. Popular varieties of summer-dormant succulents include Kalanchoe, Aloe Vera, Snake Plants, Haworthia, and Jade Plants. It follows that the fall and winter are when they genuinely awaken and grow. In other words, they will only require low-normal watering levels. Discovering your plants’ dormancy schedule will help you take better care of them.
Live succulent plants have the beauty of requiring minimal upkeep for the most part. All they want for is soil with good drainage, sporadic moisture, adequate dry spells, and adequate sunlight. These simple conditions must be fulfilled for these gems to not only survive the fall and winter, but even thrive and grow—or, depending on the species, contentedly rest until the following spring!
Prepare succulents for indoor living
Spray your succulents with a surface pesticide before bringing them inside. To ensure that your succulents are pest-free, this preparation should take place at least 3 weeks before their indoor adaption. By doing this, you can stop insects and other pests from spreading to your indoor plants.
After clearing the garbage, weeds, and leaves, look for any indications of an infestation. Change the soil if you notice flies gathering around the succulents. When you bring them inside your home, they will quickly spread to the neighboring plants if you don’t.
Make sure your succulent is in a pot with a drainage hole and well-draining soil. Because outdoor environments frequently have greater ventilation, a proper soil mixture is essential for indoor growing of succulents. Succulents need sufficient air circulation to sustain healthy roots. To improve drainage, you can also add pumice or perlite to the potting medium.
In addition to these actions, gradually cut back on the watering of your succulents. The plants will go into dormancy and be able to endure the harsh winter with the help of less water and a lower temperature.
Bring the succulents inside 
Stop watering your indoor succulents and allow the soil to dry up. Water them lightly during the winter, just enough to prevent dehydration. Ensure that the temperature is consistently between 50 and 60 degrees Fahrenheit.
Providing enough light for succulents in the winter is another factor to take into account for indoor adaption. If your succulents have been kept outdoors for a while, they may have grown accustomed to regular exposure to intense light. It’s better to replicate their growing environment indoors. A sunny windowsill can provide 6–8 hours of bright light in warm zones 9–11, but in places with little sunlight, you might want to consider obtaining a succulent growth lamp.
Fluorescent lighting will promote healthy, stress-free plant growth, especially for non-dormant succulents.
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.
In the winter, should I cover my 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.
Are succulents meant to be inside or outdoor plants?
Succulents, however, are hardy plants that may thrive in a variety of conditions, including neglect, little access to water, fast-draining soil, and a steady source of sunshine.
It’s excellent if you live somewhere where the weather is just right for them to thrive outside.
But if you don’t, you’ll need to make some alterations and adjustments.
These bizarre plants have evolved to survive in the worst conditions, including the wettest climates, little to no soil, and the steepest slopes.
A variety of surprises, including vibrant edges, tips, or complete shifts in foliage color, can be found in the sunlight or the chilly outdoors.
When succulents are grown outside, the weather will determine and set off when the plants are dormant or active, depending on the species. On the other hand, when it warms up, that can cause new births, color changes, or blooming.
When may I return my succulents to the outdoors?
Before anything else, when is it too early to plant new succulents outside?
In general, waiting until after the last frost and when the nights don’t get below 40F is advised. Even while you could grow certain succulents outside before then, planting is most successful in warmer climates.
However, avoid waiting until the summer because the heat can be just as problematic as the cold. When planting your succulents outside, look for temperatures between 50 and 70 degrees Fahrenheit.
Can succulents recover after a freeze?
Can a frozen plant still be saved? This truly depends on the kind of plant and how long it was exposed to the cold. On all save the most tropical plants, light freezes are typically something that a plant can recover from.
Remove damaged plant material from woody plants in the spring. In the late winter, you can detect which stems are dead by scratching the bark. The tissue is still alive if the substance is green below. They will lose their leaves as a result of the freezing, but they normally re-leaf in the spring. After all threat of frost has passed, maintain the plants’ moisture and apply a mild fertilizer.
More delicate plants won’t be able to endure the freezing damage and will turn into annuals. Perennial plants that have been frozen-damaged may only have little root damage, in which case you can divide the plant and replant the pieces. The ones that recovered from the root area’s cold did not deal a fatal blow.
Succulents: Do they require frost protection?
“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.

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.
