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 may be outdoors in the winter.
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.
What temperature is too low for a succulent?
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.
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.
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.
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.
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.
How are succulents maintained outside?
Various pots are ideal for succulent growth. If the water level is carefully controlled, those who live entirely indoors can occupy nearly any form of receptacle, from teapots to terrariums. But in the open air, strong rains can soak succulents. Use of containers with drainage holes is essential because to this. The best containers are made of terra cotta because they naturally wick moisture from the soil. In order to ensure the best drainage, succulents should be potted in a light succulent soil mixture.
Succulents in pots that are kept outside won’t require nearly as much watering as those planted in the ground. However, check in with your plants if the weather is extremely hot or dry. The leaves seem shriveled. Does the ground seem to be dusty? If so, a drink is probably in order. While it’s true that most succulents benefit from lots of sunshine, others thrive in shadow or partial exposure. Make sure the succulents in your planter need a similar amount of light, then place them where they will thrive in your yard.
Succulents withstand snow?
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.
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.
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.
