Succulent plants called sedums thrive in climate zones 3 to 9. Sedum is one of the toughest succulents available due to the fact that succulents are notorious for storing water in their leaves. Sedums can withstand hot weather, dry soil, and cold temperatures. Sedum won’t need a lot of winter maintenance, unlike most perennials.
Sedums can be neglected when you tidy up and cut your garden space for the winter. Sedums are hardy plants that can withstand cold and temperatures below zero. Sedums that are standing upright will eventually fade back to the ground, but the surviving stalks with spent flowers will still provide color and food for the birds. Pruning the stalks all the way to the ground is an option. The plant and the spring’s fresh growth won’t be harmed.
For frost, do I need to cover my sedum?
My new succulents, which I planted in containers over the course of last summer, have practically turned to mush as a result of the most recent cold spell, Howard writes.
The succulents’ growing zones in my garden saw temperatures as low as 27 degrees Fahrenheit.
Do any succulents have the ability to withstand colder temperatures? What can I do going forward to prevent freezing damage to the plants? Additionally, do you have any helpful suggestions for extra growing techniques? I’m not prepared to give up on the “succulent challenge” just yet.
I spoke with Charolett Baron, an expert succulent and cactus aficionado, and I inquired about how her collection of succulents had fared through our abnormally cold conditions.
She also revealed some of the hard lessons she had to learn about cultivating succulents after she too lost some of her favorite specimens in a prior cycle of extremely cold temps.
Here are some of her tips for choosing succulents that can withstand freezing weather as well as what she does to safeguard her collection of succulents and cacti:
She has discovered that the agave, “After Glow,” is more tolerant of freezing temperatures and that the yucca, “Wall Bright Star,” is resilient to 0 degrees. These examples were discovered by Baron at Petaluma’s Cottage Gardens.
Specimens with variegation appear to be less robust. Frost is not tolerated by euphorbias. Despite the fact that they are supposedly hardy to, say, 30 degrees, container plants are more sensitive to lower temperatures.
Crassula sarcocaulis can withstand temperatures as low as 10. Hens and chicks, often known as sempervivums, can endure freezing temperatures. Stonecrops, commonly known as sedums, survive the freezing temperatures with little obvious damage.
Baron advises covering ALL of your succulent plants in breathable, frost-protective cloth that enables moisture and sunlight to pass through.
Although they must be removed during the day, thin sheets thrown over the plant in cold weather also works nicely.
Place the containers in sheltered spots like eaves. Wait until the weather warms up before going out on the water.
Run some low-voltage lights in your mini-greenhouse or bigger structure for added warmth, and keep the pots lightly covered in floating row covers—a frost-protective material—until no longer necessary.
Finally, her own succulent plants have survived because she covered them, including those in her greenhouse, in the ground, and in pots.
When the temperature dropped to 28 degrees, the sedums, sempervivums, Orostachys, Senecio mandraliscae, Crassula cocinea ‘Campfire,’ Rhodiela, and Aloe nobilis in my garden were unharmed.
Read the plant label before buying succulents because it will usually indicate whether or not the plant is cold-hardy. Some species within a given genus may be more resilient than others.
A protracted rainy period like the one we had will also reduce hardiness, as will the number of days with low temperatures.
The slightly more fragile succulent variety can be successfully grown by readers who live in a warmer area.
Surprisingly, visiting nearby neighbors who have had little to no plant frost damage will also assist you choose which succulents will do well in your own garden.
“Succulent Container Gardens, Design Eye-Catching Displays with 350 Easy-Care Plants” by Debra Lee Baldwin is a fantastic resource for all succulent fans.
This book provides answers to many queries regarding the cultural requirements of succulents, the hardiness of specific plants, and attractive container arrangements that use color, texture, and size that are appropriate for each container.
What distinguishes a yucca from an agave in terms of appearance, queries Cynthia?
Yuccas are mounding succulents that grow 2 to 3 feet tall and feature spiky foliage with stringy hairs along the margins. In the early or middle summer, they produce flowers on stalks.
Agaves grow in clumps and have leaves that are about 18 inches long, 3 inches wide, and have sharp, pointed points. Agaves, commonly referred to as century plants, don’t flower often, but when they do, it’s usually on stalks that extend several feet above the clump of foliage.
Is it acceptable to graft a citrus tree onto a camellia? asks Jess S. If it is not required, avoid removing the camellia’s root system.
What temperature is too low for sedum?
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 contrast to southern California’s sunny environment, where there are many beautiful succulent gardens, Utah’s four-season climate makes it more difficult to find outdoor succulent gardens.
The two main types of succulents that can withstand freezing temperatures are Stonecrop Sedums and Sempervivums, also known as hens and chicks. Most animals can survive at temperatures as low as –20 °F.
In order to maintain a stunning outdoor succulent garden year-round, even when there is snow on the ground, I have been developing a variety of arrangements using only cold-hardy succulents.
You’ll see affiliate connections to Mountain Crest Gardens for the many succulents I utilized for these projects all throughout this post.
I received a lot of succulents for free, but my favorite succulents are from Mountain Crest, and I wholeheartedly suggest them to everyone! Nowhere else will you find a finer collection of resilient succulents.
In the movies below, you’ll see a wide variety of succulent collections and items, but I wanted to make it simple for you to see them all at once, so here is a list of the things I used to produce these succulent landscapes:
Should I protect my succulents from the cold?
Succulents that are native to warm, arid climes can perish in wet soil, dim light, high humidity, and freezing temperatures. You can use these products to protect your succulents from the harsh, wet winters in North America. (Advertising connections.)
You could just require frost cloth if you live somewhere where frost is sporadic. (Old bed sheets also function.) This helps keep warm air from dispersing into the higher atmosphere and stops ice crystals from falling from the atmosphere from falling on plants. Don’t cover your succulents with plastic sheets that resemble trash bags; whatever material you use should let air to circulate. If plants are covered for extended periods of time, translucent cloth is a must. However, removing the frost cloth throughout the day is ideal.

Floating row covers made by Agribon and Pellon nonwoven fabric can both be used. Spun nylon, often known as “floating row cover,” is similar to fusible interfacing but lacks the fusible component. It can be used as a sunscreen, insect barrier (against cabbage moths, etc.), and frost protection. It is permeable to water and allows vapor to pass through. It will provide protection from -2 to -4 degrees below zero. Use C-9 Christmas light strings for added warmth.
Succulents that are in pots can be covered or moved to an overhang till spring. Depending on how cold it gets, beneath your home’s eaves or on a deck or patio (near the house) may be sufficient. The warmth that walls give out may be sufficient to elevate the temperature above freezing.
Consider purchasing a compact walk-in greenhouse that can be disassembled and stored during the warmer months if you live somewhere where the temperature drops into the 20s. Put it in a location where a portable electric heater’s cord may reach from your home.
If you must (or choose to) keep your succulents inside for the winter, equip a basement, sunroom, spare room, or alcove with shelves and tables that can handle wetness as well as timer-controlled lights and a fan. Fortunately, the bulk of dormant succulents—those that fall dormant in the winter—need relatively little water. Every three weeks or so, dribble a small amount at the base of each plant, just enough to water the roots but not enough to create pools on the ground.
mount grow lights. Light is a plant that loves it. T-5 grow lights are advised by experts in indoor gardening and growing succulents in environments with low visibility. These will maintain the color of your echeverias!
Is every sedum Hardy?
Sedum (Sedum spp.), sometimes known as stonecrop, is a hardy succulent with 400 or so varieties that produce star-shaped flowers that are attractive to butterflies and come in pink, white, red, or yellow. Despite the fact that certain sedum varieties prefer warm climates, the majority can survive in USDA plant hardiness zones 3 through 9. The success of the plant depends on understanding which type of sedum to grow in a certain zone because such areas encounter cold temperatures.
Are sedums resilient?
SedumShack Hardy, strong, yet beautiful flowering succulent plants, sedums are. On every garden location—on roofs, in walls, containers, baskets, or in between paved or gravelly areas—they are dependable, trusted plants. They will repay you with luscious leaf colors and beautifully rich bloom colors if you don’t feed or water them. Purchase your hardy perennial succulents in our SHOP. They’re simple to grow and maintain.

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.
I have succulents, when should I bring them inside?
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.
