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.
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.
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 degree of heat can sedums withstand?
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.
Are all sedums resilient?
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.

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:
Will succulents endure a cold winter?
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.
What plants should I protect against frost?
The first is where your garden is situated. Some delicate plants may thrive perfectly well in a well protected outdoor environment, but this wouldn’t be the case in a more exposed setting.
The type of plant and whether it is categorized as “hardy” or “tender” are both significant factors.
Plants that are hardy can typically withstand a brief period of freezing temperatures. But keep in mind that most plants could possibly perish in a harsh frost of -2C or lower. Clematis, honeysuckle, heuchera, euphorbia, hydrangeas, buddleja, rhododendrons, and various types of roses are popular cold-hardy plants.
In order to withstand a strong frost, tender plants—also known as semi-hardy or half-hardy plants—usually need to be sheltered or brought indoors for the winter. Fuschia, dahlias, pelargoniums, tree ferns, canna lilies, begonias, and various succulents are examples of popular sensitive plants.
The care label that comes with the plant or a fast online search will help you determine whether a plant is hardy or fragile. There are some excellent plant identification applications available if you don’t know the variety of your plant. Alternatively, you may go back to last winter—did the plant survive the frosts then?
Remember that some winters are worse than others when choosing this last choice, and a plant that survived last year might still struggle this year. If you’re unsure, I believe it’s advisable to err on the side of caution and safeguard your plants.
Finally, plants with recent development and young plants are more susceptible to damage from frost. Give this particular attention.
What degree should you cover your plants with during the night?
Planting too early might result in a crisis if a cold snap is impending, whether it was because you were seduced by some striking hue at the garden center or simply wanted to start the gardening season early. It’s not difficult to help your seedlings survive the great frost, but it does take some planning.
When temperatures drop, you can usually rely on improvised protection for plants. The necessary tools must be prepared in advance to protect plants from frigid mornings for larger plantings, such as a food garden.
Knowing when prized vegetation starts to turn frost-burned brown will help you know what to do when freeze warnings are in effect. As a general rule, plants typically freeze when the temperature stays at 28°F for five hours.
There are, of course, exceptions to this rule. When temps drop to 32–33F, seedlings often die because of their delicate new leaves. There are many low-temperature thresholds for tropical plants. Some collapse at temperatures below 40°F, while others break down at 35°F. Other plants are naturally resistant and can endure temperatures as low as 18 to 20 degrees Fahrenheit. Do a search in gardening books and internet resources to discover the threshold for your plants.
Take it up
Moving plants away from potential danger is the simplest cold-protection strategy. Potted plants and seedlings in flats both benefit from this. Moving plants onto a porch with a roof, into a garage or shed, or under a deck frequently provides sufficient shelter.
Rely on Water
Just before sunset, water the soil to raise the temperature of the surrounding air overnight as the water evaporates. Water-filled buckets or gallon jugs should be left in the sun all day. Move them close to threatened plants at night. Air temperatures will be moderated by the water, and if it freezes, heat will be released. To boost midday heating, paint a few water-holding containers black for best results.
the air flowing
The biggest harm is done to plants by cold, motionless air. To prevent frost from accumulating on plants, you can use an electric fan all night to create a breeze. Never forget to keep electrical connections dry.
Plants Should Be CoveredPlants should be covered with sheets, towels, blankets, cardboard, or a tarp to protect them from everything but the harshest freezing (28F for five hours). Inverting baskets, coolers, or any other container with a firm bottom over plants is also an option. Before it gets dark, cover plants to keep warm air in. Coverings shouldn’t ideally contact the foliage. If windy conditions are anticipated, anchor cloth coverings.
When the temperature rises and the frost has melted in the morning, remove coverings. Under dense covers, heat from the sun can accumulate and cause plant death.
Blankets that collapse
Row covers, or gardening blankets, should always be accessible. These covers are created in various thicknesses from plastic or synthetic fibers. Lay row covers directly on the plants, or suspend them over a bed with pegs to form a tunnel.
Activate lights
An incandescent light bulb produces enough heat to raise the temperature of the air around it just enough to keep a plant from freezing. For this method to operate, bulbs must be close to plants (within a distance of 2-3 feet). (Fluorescent bulbs can’t produce enough heat to complete this task.)
Defend specific plants
Set up hot caps
At planting time, stiff plastic containers with venting holes are placed over the individual seedlings. Hot caps function similarly to cloches (small greenhouses), but the daily task of applying and removing the covering is eliminated by venting holes. Use plastic two-liter bottles or gallon jugs with the bottoms cut off and the lids removed to simulate a hot cap (but saved). In the evenings when the weather turns chilly, replace the lids.
A Wall O’Water tepee, which encircles individual plants with a sleeve of water-filled tubes, is a variation on the hot cap concept. During the day, the water absorbs the heat of the sun. The water gently freezes at night, releasing the sun’s stored radiant heat and preventing the air within the tepee from becoming frosty.
Will sheets on beds shield plants from frost?
QUESTION: Fabric or plastic is the best material to use as a cover to shield outside plants from the chilly air.
When the temperature drops low enough to cause the moisture on plant leaves and buds to freeze, the threat of frost typically materializes overnight. You must cover plants to prevent the moisture from freezing in order to protect them from cold. It’s crucial to utilize the proper materials, even though an unexpected cold can leave many gardeners racing to find something to cover their sensitive plants.
It is ideal to use a cotton covering because it will let moisture out while yet shielding your plants from cold. Fabric coverings will both capture the heat that is radiating from the ground and stop the freezing air from coming into direct contact with the wetness on the plant. Large plants and shrubs are best covered with bed linens or comforters. Newspaper can be used to low-growing vegetation, but it can frequently be challenging to make it stay put. I have recycled old towels, sheets, and even cardboard boxes as well as pillowcases. Whatever you choose to use to cover your plant, just make sure the canopy traps the warm air within and extends to the ground.
You can use plastic, but it’s crucial to remember that you shouldn’t let it touch your plants. Because it can hold moisture against plant tissues and worsen freezing damage, plastic that comes into contact with your plants is frequently much worse than no protection. For their frost-sensitive plants, many gardeners will frequently install high stakes or forms so they can cover them and secure them without worrying about the coverings blowing away at night or harming the branches. As long as the plastic won’t come in contact with the plant in any manner, it is acceptable to cover a structure like this with plastic.
And keep in mind that the more cover layers there are, the better the insulation is. So, feel free to cover priceless or delicate plants with more than one cover, especially during really cold temperatures. You may, for instance, cover the plant with a sheet of plastic and then an old blanket.
Whatever method you choose, it’s crucial to remove the covering as soon as the risk of frost has gone so that the plant can absorb light and to avoid heat buildup when the sun comes out.
