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.
How can you survive the cold with succulents?
Many of the most popular and stunning succulents will need to be taken indoors for the winter unless you are fortunate enough to live in a place where it does not get below freezing. Although a greenhouse is ideal, few gardeners have access to one. Fortunately, it’s simple to overwinter most succulents inside.
There is a vast variety of various plants classified as succulents, some of which have very particular requirements. But the advice provided here will help most widely cultivated succulents survive the winter.
When grown inside, succulents frequently develop a habit of being stretched out and lanky, producing weak and unsightly plants by spring. When care for succulents indoors throughout the winter, light, water, and temperature are three crucial considerations that can help to reduce this.
Light is Critical
Light is the main component in succulent survival during the winter. Succulents will extend if there is insufficient light in an effort to get closer to the source. In general, succulents want full sun. Although it can be challenging to do so inside, expose them to as much direct sunshine as you can. The ideal window is one that faces south, though east or west windows can also be used.
If there is inadequate natural light, fluorescent lights may be employed. It’s crucial to keep the plants between the bulbs and 1 to 2 inches away from them. Over a distance of 3 inches, fluorescent light is practically useless to plants. For plant growth, incandescent lights emit the wrong spectrum of light and becoming too hot.
Succulents Need Little Water During the Winter
It is always preferable for succulents to be too dry than too moist. This is particularly true in the winter, when plants experience less-than-ideal lighting conditions and below-average temperatures. During the winter, keep your succulents on the dry side. Just enough water should be provided to prevent plant shriveling. You might just need to water once every 10 to 14 days in a cold area.
Keep the plant itself dry at all times, especially rosette plants like Echeverias. The plant will swiftly decay and become mush as water will collect in the rosette’s center. Keep in mind that keeping a succulent moist will destroy it quickly!
Cool Temperatures are Good
The majority of succulents do not require extra warmth during the cold. It’s crucial to prevent them from freezing. The ideal temperature range is between 45 and 55 degrees Fahrenheit. The plants will remain in a semi-dormant state if kept cool. With the lower light intensity indoors during the winter, a warm environment fosters the growth of the plants, resulting in lanky plants.
No Fertilizer Needed
During the autumn and winter, succulents do not require any fertilizer. Instead of encouraging the plants to develop, you want to maintain them alive.
I’ve had great luck using these methods to overwinter plants like Echeveria, tender Sedum, Aeonium, Agave, Aloe, Crassula, Graptoveria, Kalanchoe, Faucaria, and Senecio.
The plants may endure the winter in a semi-dormant state with little stretching if you keep them sunny, dry, and cool. The succulents can be put back outside for a summer of sunbathing once the weather is no longer frosty.
Succulents should be taken indoors for the winter.
Each summer, soft succulents can enjoy some sunshine outside, but they must return indoors before it becomes too cold. Pay attention to the light, air, soil, and water conditions as you bring your plants indoors for the winter.
Light
Naturally, indoor places receive less sunlight, especially during the winter. Sun-loving succulents should be placed close to a sunny window. To stop the pots from fading and straining, rotate them frequently. Add a grow light to rooms that don’t get enough natural light, or try indoor succulent varieties. For rooms with particularly low light levels, we suggest Haworthia, Jade, and Gasteria.
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.
In the winter, how frequently should I water my succulents?
During the months that are not winter, when the temperature is above 40 degrees, you should water your succulents every other week. You should only water your succulent once a month in the winter (when the temperature falls below 40 degrees), as it goes dormant at this period.
A few situations constitute an exception to this rule. Because their tiny leaves can’t hold as much water as other varieties with larger leaves, some varieties of succulents need to be watered more frequently. In the non-winter months, feel free to give these small leaf succulents a water if they appear to be thirsty. When they are thirsty, succulents generally exhibit a wrinkled appearance. But always keep in mind that being underwater is preferable to being overwater.
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.
Succulents do not hibernate inside.
True dormancy is not experienced by succulents cultivated indoors. As a result, you’ll discover that propagating or transplanting succulents indoors throughout the year is not a problem.
Waiting until the succulent is in its active growing season is optimal for succulents growing outside. The spring and fall seasons are often when you’ll see the best effects.
Extremes in temperature will be your main obstacles when transplanting or planting succulents outdoors.
For my sister-in-law in Southern California, I planted several succulents. The succulents were outside in the ground when we planted them in June, but because of the heat wave, they were experiencing temperatures near to 100F. (38C).
These little 2 (5 cm) succulents didn’t have time to adjust to that scorching temperature and the full sun because the place we were putting them in was also in full sunlight. The majority of them perished.
Even cold-hardy varieties of succulents would freeze if I tried to plant them outside in the midst of the winter when I still lived in Utah since they weren’t used to the extremely cold temperatures.
Succulents can, however, be planted all year round provided you give them a beautiful, temperate climate without too many extremes.
Because (shocking, I know…) they are growing more throughout their active growing season, you’ll discover that your succulents take transplanting better. As a result, they will heal more quickly and acclimate to their new surroundings more quickly.
The process of propagating succulents is comparable. In the end, spring or fall, when that particular succulent is beginning its active growing season, are the greatest times of year. The growth of these plants can be propagated at other seasons of the year, but it will often be slower.
Again, this is relevant to succulents grown outside. Succulents grown indoors can be easily reproduced all year long and develop at a similar rate.
Succulents can they survive indoors without sunlight?
The most light is reflected from south-facing windows throughout the day in the northern hemisphere. The sun shines through windows facing east in the morning and west in the afternoon and evening. The least quantity of sunlight enters windows that face north.
A south-facing window is the best choice for the majority of sun-loving succulent plants in the northern hemisphere. However, all of the low-light succulents covered in this article happily flourish in windows that face west or east. Even in a dark, north-facing window, some of them will make it, but I don’t advise it because even there, they won’t thrive.
However, no succulent can live in a completely dark environment. Therefore, even if your succulent plants are varieties that thrive in low light, think about buying a tiny desktop grow light if you live in a basement flat, have only a north-facing window, or if your space has no windows at all. When a modest grow lamp is placed over low light succulents for 6 to 8 hours a day, you’ll be astounded at how well they grow. You won’t need to remember to turn the lights on and off every day if you have a reliable timer.
Now that you are aware of how much sunlight low light succulents require, allow me to introduce you to some of the greatest low light succulents.
I have succulents, when should I bring them inside?
When you should bring your succulents indoors depends on a few different factors. These elements include your residence and the crops you raise.
Generally speaking, succulents need to be moved inside before the first frost. Typically, this occurs at the end of September.
Bring your succulents indoors when the weather starts to cool down if you live in a hotter climate.
When nightly lows fall below 50 degrees Fahrenheit and daytime highs do not consistently reach 80 degrees Fahrenheit for a few days, it is time to bring them inside.
Typically, this is the time when they start to feel chilly and show symptoms of stress or illness, such as shriveled growths or falling leaves (especially if this has happened before).
Some species, such rosette forms, can tolerate colder wintertime temperatures, but the majority of species require warmer conditions year-round—at least 50 degrees F.
Any tropical kinds growing outside will need to be moved inside when the overnight lows reach the 40s.
When it starts getting darker earlier in the day, that is another consideration when deciding when to bring succulents indoors.
If your days are still long and sunny, it won’t be essential to bring them inside just yet. However, this becomes necessary when nightfall arrives earlier than anticipated (before sunset).
Which Succulents Need To Be Brought Inside During Winter?
Based on how well they tolerate cold temperatures, succulents can be split into two groups: cold hardy succulents and soft or fragile succulent plants.
The only succulents that can tolerate frost when the temperature drops below a particular level are cold hardy (deciduous) succulents. When the temperature is between 20 and 25 degrees Fahrenheit, these succulents can remain outside all winter (-28.88C).
Some cold-tolerant succulent plants may not be able to tolerate dry indoor heating when brought inside for the winter, and they may become dehydrated.
Tropical or subtropical species known as tender succulents must be brought indoors during the winter months because they cannot tolerate frost below a particular temperature.
When it is at least 50 to 60 F outside, soft succulents can be kept (28.88C).
What degree of heat should I provide for my 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.
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.

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.
