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.
How cold should it be for succulents?
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.
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.
What should you do with succulents in pots throughout 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!
Where should succulents be kept throughout the winter?
Making sure succulents receive adequate sunshine indoors, especially during the winter, is one of the most challenging aspects of indoor succulent gardening.
Your succulents should be placed next to the room’s brightest window. The ideal window will receive all-day, brilliant indirect light.
This is crucial because the days are shorter in the winter. To retain their shape inside, succulents require at least 8 hours of bright, indirect sunlight each day.
Your succulents may start to spread out or lean toward the window during the winter months when there are a lot of gray or cloudy days. They aren’t getting enough light, as evidenced by this.
You can rotate your succulents in this situation to help correct any leaning. However, you will need to supplement with a grow light to avoid stretching.
Make sure the lights aren’t on all the time because succulents require darkness at night to complete their normal growth cycle.
At the conclusion of the winter, you can take off the tops and propagate any succulents that do start to stretch out or get tall and lanky. After that, you’ll have an abundance of summertime plants!
This is best done in the spring because most succulents don’t grow as quickly throughout the winter. Check out my post on extending succulents for more information on how to achieve this.
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.
Do my succulents belong 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.
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.
