A wide variety of succulents that are less tolerant of low conditions than “hardy succulents” are referred to as “soft succulents” (also known as “sensitive succulents”). Although certain plants in the category can be grown down to USDA Zone 7, we generally classify species designated USDA Zone 9 (20 to 30 F) and above as Soft Succulents (0 to 10 F). In locations without frost (USDA Zone 10+), all soft succulents can be cultivated outdoors. They can be cultivated in containers and brought indoors for the winter in colder climates.
The degree of hardiness varies greatly amongst the various varieties. Most Soft Succulents, including several Echeveria, have rosettes of thick, fleshy leaves that are somewhat hardy to at least the mid-20s F. Soft succulents with smaller individual leaves, like the majority of Kalanchoe, may endure temperatures below freezing for a short period of time, but when the temperature reaches the mid-20s F, they die from the roots up. Due to their moderate hardiness, they can survive outdoors in places that only sometimes see mild frost (such as many coastal areas) and in well-protected areas in colder climates.
Succulents may be grown outside in Zone 6.
Succulent cultivation in zone 6? That seems possible. The majority of hardy succulents can withstand the severe winters in zone 6, where temperatures can drop as low as -5 F. Succulents are typically thought of as plants for arid, desert areas (-20.6 C.). In fact, just a few species can endure harsh winter conditions as far north as zones 3 or 4. Continue reading to discover how to choose and cultivate succulents in zone 6.
Succulents can they be grown outside in Zone 5?
Succulent varieties for Zone 5 Since many succulents are extremely flexible, they can flourish in climates ranging from 4 to 9. These hardy plants simply need spring and summer sun and well-draining soil to grow.
Succulents can they survive outside in Zone 7?
The varied succulent family offers a wide variety of hues, shapes, and textures. If you live in a cooler USDA growing zone, cultivating succulents outdoors can be challenging. Fortunately, zone 7 is not very harsh, and the majority of succulent plants can survive its comparatively moderate winters. Succulents are among the easiest plant species to maintain, and their enormous variety and endearing appearance give the landscape a quirky, playful feel.
Succulents can be grown in Zone 4?
Most of Alaska and a few of the most northern US states fall inside hardiness zone 3. The minimum average temperature ranges from -40 to -30 degrees Fahrenheit. This region of the US suffers some of the coldest winters, high wind, and minimal precipitation because of its primarily continental climate. The majority of plants are challenging to grow over the long winter when temperatures frequently drop below freezing.  
Zone 4 includes parts of Alaska’s highlands and northern and southern coasts. Different climates come from the huge area covered by the earth’s surface. Some mountainous states, like Wyoming, have dry, windy weather, while others have a more humid environment. Zone 3’s minimum temperatures often range from -30 to -20 degrees Fahrenheit.
Minnesota, North and South Dakota, Wyoming, and Wisconsin are typical states in zones 3 and 4.
WHAT TYPE OF SUCCULENTS THRIVE IN ZONE 3 & 4
Growers’ options for plants are limited by the lengthy and harsh winter. Sedum Stonecrop and some members of the Sempervivum genus, such as Sempervivum Red Lion and Sempervivum Mahogany, are hardy succulents for zones 3 and 4.
Succulents—can I leave them outside in the 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. Those are termed “Hard Succulents”. Some of the most cold-hardy succulents belong to the Sempervivum, Sedum and Euphorbias genus. You may plant such succulents outside all year round because the majority of them can withstand temperatures as low as -20F (Hardiness Zone 5).
Other succulents that are more sensitive to frost are “Soft Succulents”. When the weather drops below freezing, they must be winterized inside.

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:
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.
In the cold, do succulents freeze?
The fact that many succulents can survive outside year-round, even in snowy climes, surprises a lot of people. We divide succulents into two categories—”hardy” and “soft”—to make it easier for you to choose the best one for your area.
- Hardy succulents: Tolerate frost and can endure temperatures below zero outside. They are perfect for outdoor gardening all year long. Hardy succulents actually thrive outside more than they do inside.
- Not frost-tolerant are soft types. Before temperatures drop below freezing at night, these types must be brought inside. On the other hand, when the warm, sunny weather returns, they are glad to go outside once more.
the USDA Grow Zone finder (based on minimum winter temperature). You may find a plant’s “Cold Hardiness” on the description of each one in our online catalog. If your zone number is equal to or higher than the plant’s, that variety can endure the entire year outdoors in your environment. The plant will need to be brought indoors before the fall temperatures start to drop if you live in a zone with a lower number than the Cold Hardiness of the plant.
Most of our plants are also sent with name tags that state the lowest temperature they can withstand for easy reference.
Zones 4 and higher are suitable for Sempervivum heuffelii’s growth, however zones 3 and lower are not.
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 but 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 succulents endure the winter in Zone 8?
Most of the southern coastal parts of the US fall under Zone 8. States in zone 8 are considered to be cultivated sites for many varieties of succulents because it is one of the warmest zones, with a minimum temperature of 10–20 degrees F.  
Georgia, Mississippi, Texas, Louisiana, Alabama, South Carolina, and North Carolina are typical zone 8 states.
WHAT TYPES OF SUCCULENT THRIVE IN ZONE 8?
Zone 8 hardy succulents should benefit from a warm winter and scorching summer. Cactus, Sedum, Sempervivum, and some Echeveria are examples of such succulents.
Succulents can they endure in Zone 8?
Succulents in zone 8 are particularly tolerant of shifting weather and can thrive there. Boggy soil or places that don’t drain well are two things they cannot tolerate. Even plants grown in containers need to be in a loose, permeable potting soil that has lots of pores for water to drain through.
If the soil is clay or compacted, in-ground plants benefit from the addition of some grit. To loosen soil and enable for thorough percolation of moisture, fine horticultural sand or even small bark chips work well.
Place your succulents so they will get all day long sun without getting scorched in the midday sun. The majority of succulents don’t require much watering from the outdoors; nevertheless, in the summer, irrigate occasionally when the soil feels dry to the touch.
How are succulents maintained outside?
Succulents may not need much attention, but they do need a few essentials to survive:
- 1. Provide plenty sunlight. Succulents require adequate light—at least six hours each day of direct sunlight. Maintaining succulents outside can be quite simple. However, if you have a succulent indoors, you must keep it in direct sunlight near a window. A plant that is slanting toward the light is not receiving enough sunlight, yet a plant with burnt areas on its leaves is receiving too much direct sunshine.
- 2. Use proper water. Depending on the season, succulents might have different water needs. A succulent’s longevity rises when its roots have time to dry out between waterings. During their growing season, succulents should be watered every time their soil entirely dries out and avoid adding excess water. In the chilly winter months, succulent plants go dormant and require less water. Only water your succulent as often as necessary because overwatering the soil is one of the main reasons of most development problems.
- 3. Use the proper soil and pot combination. The appropriate container and potting soil can make all the difference, whether you’re growing your own succulents or purchasing one from a nursery. Your succulent planter needs to include a drainage hole if it is going to be an outdoor succulent. Proper drainage allows moisture to escape, allowing the soil and root systems to dry and prevent rot. Use well-draining soil instead of standard dirt if you have an indoor succulent. It is coarser than regular soil, enabling more air to pass through and encouraging evaporation rather than requiring to be drained. To increase aeration, perlite and pumice can be added to some potting mixtures.
- 4.Remember to fertilize. The periodic fertilizing is beneficial for even low maintenance desert plants. To give your succulents a boost, use a diluted, water-soluble all-purpose fertilizer a couple times a year. Although it’s not entirely required, if you notice that your soil needs some help, add a little fertilizer.
- 5. Examine your plant life. Pest hazards are more likely to affect a succulent indoors than outside. Gnats and mealy bugs are a sign that your plants are being overwatered or overfertilized, so check your plants frequently to make sure they’re free of them. Mealy bugs can lay hundreds of eggs and consume the plant juices that serve as their host, gradually harming your plant. Rubbish alcohol can be sprayed on your succulent’s leaves or soil to effectively kill mealy bugs and their eggs. Check the leaves and soil of the succulent before bringing it home from the nursery to make sure no bugs are present.
