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:
What temperature is too low 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.
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.
Are succulents too cool for 50 degrees?
You might be curious about the lowest temperature at which succulents cannot survive when taking care of them. Warm, arid regions are where these plants are native. Nevertheless, while some succulents can endure colder temperatures, others cannot. What degree of cold is therefore too much for your succulent?
Any temperature below 50 degrees Fahrenheit is too chilly for succulents, which typically require temps between 50 and 80 degrees Fahrenheit. Depending on the species, a succulent’s lowest temperature tolerance varies.
Prepare succulents for indoor living
Spray your succulents with a surface pesticide before bringing them inside. To ensure that your succulents are pest-free, this preparation should take place at least 3 weeks before their indoor adaption. By doing this, you can stop insects and other pests from spreading to your indoor plants.
After clearing the garbage, weeds, and leaves, look for any indications of an infestation. Change the soil if you notice flies gathering around the succulents. When you bring them inside your home, they will quickly spread to the neighboring plants if you don’t.
Make sure your succulent is in a pot with a drainage hole and well-draining soil. Because outdoor environments frequently have greater ventilation, a proper soil mixture is essential for indoor growing of succulents. Succulents need sufficient air circulation to sustain healthy roots. To improve drainage, you can also add pumice or perlite to the potting medium.
In addition to these actions, gradually cut back on the watering of your succulents. The plants will go into dormancy and be able to endure the harsh winter with the help of less water and a lower temperature.
Bring the succulents inside 
Stop watering your indoor succulents and allow the soil to dry up. Water them lightly during the winter, just enough to prevent dehydration. Ensure that the temperature is consistently between 50 and 60 degrees Fahrenheit.
Providing enough light for succulents in the winter is another factor to take into account for indoor adaption. If your succulents have been kept outdoors for a while, they may have grown accustomed to regular exposure to intense light. It’s better to replicate their growing environment indoors. A sunny windowsill can provide 6–8 hours of bright light in warm zones 9–11, but in places with little sunlight, you might want to consider obtaining a succulent growth lamp.
Fluorescent lighting will promote healthy, stress-free plant growth, especially for non-dormant succulents.
Succulents should be brought inside when?
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.
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.
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.
Do I need to protect my succulents?
Before you even plant your succulent in your yard, this is the easiest way to find out if it will survive the winter in your region. The USDA Plant Hardiness Zone Map is referenced on the labels of the majority of plants that are sold in retailers. The label will indicate whether or not the plant will survive the winter depending on the zone you live in. The zones are separated by a difference of 5 to 10 degrees Fahrenheit in their lowest annual temperature. There is minimal likelihood that it will survive the winter in that area if your zone is lower than the recommended zone on the label.
Tip #2: Bring Them Indoors
Bring your succulent indoors during the winter even if it is in the right climate zone. Even though sudden temperature dips are uncommon, one chilly night is all it takes to harm your plants. They can be kept in your garage if the temperature there doesn’t fall below 50 degrees Fahrenheit. Don’t forget to give them three to four hours of indirect sunshine each day. Checking for insects like mealybugs and aphids is a crucial factor. Spray the leaves with a mixture of 1 part water and 3 parts rubbing alcohol to kill the bugs because you don’t want them inside your house.
Although it’s frequently overlooked, preparing your put for indoor play is crucial as well. Your succulents’ containers are probably a little muddy if they have been playing hard outside. To prevent them from spreading around your home when you transfer things inside, first clear the pot of any dead leaves and other debris. Second, clean off any extra dirt from your pot; you want a clean transition from the inside to the outside! Lastly, look for bugs. Creepy crawlies taking over your house is the last thing you need. You should be well on your way to your indoor succulents thriving after following those three steps.
Tip #3: Reduce Watering in the Late Fall
Winter is the period when succulents go dormant, so watering is even less necessary. So once the weather becomes colder and the days get shorter, stop watering them. Reduce it to once a month, but you should also check the soil’s moisture content first before watering. When the ground is entirely dry, only do it. It only takes a good five minutes to water. To prevent succulents from dying from moist roots, check that the soil has excellent drainage. Sand or organic matter with good drainage should be added to the soil for indoor plants. Mulch shouldn’t be used near the base of outside plants since it can trap moisture.
Before you fully stop watering your succulents, here’s a short tip: identify them! Winter is when most succulents go dormant, however some are winter growers. The plants that don’t go dormant will require more water than the others. Keep an eye on things at least to prevent your freshly indoor succulents from becoming overly dry. (Succulents will dry out more quickly than others if they are close to vents or heaters.
Tip #4: Sunlight
When putting your succulents indoors, sunlight is absolutely crucial! Making sure they receive adequate sunlight in the winter is challenging. To get the most indirect light, place your succulents close to your home’s brightest window. Try to provide succulents with at least 6 hours of sunshine each day for the healthiest results. They’ll begin to slant toward the window if you’re not providing them with adequate sunshine. Simply turn them the other way to straighten them out.
Tip #5: Cover Up Your Succulents
If you are unable to bring the plants inside due to impending cold weather, you can cover them with various forms of protection. Snow covers are beneficial because they provide protection from snow, frost, and strong winds. You can buy them from your neighborhood garden supply store or online. Bushel baskets can be used to cover and safeguard succulents if you have any lying about. Just be cautious not to leave them covered for an extended period of time. The plants require ample sunlight and clean airflow.
These straightforward suggestions can help you keep your succulents happy and healthy throughout the winter. Give your friends and neighbors the information so they can preserve their succulent plants as well!
What succulent is the hardiest?
A sizable genus of succulents is called agave. Their pointed leaves and rosette formations serve as identifying characteristics. There are many different agave species; some are small plants that don’t reach heights of more than 10 feet, while others are enormous. They can be grown in the ground or in pots and other containers. They don’t need much maintenance and can survive in a variety of environments, including full hot sun and mild shade. Some species are cold-hardy as well. These plants are excellent for anyone searching for a low-maintenance, simple plant. They are resilient and challenging to kill.
A large and well-known genus called Aloe contains small dwarf species and large tree-like species that can reach heights of up to 30 feet (10m). They feature large, fleshy leaves that range in color from green to bluish green. On the stem surfaces of some kinds, there are white flecks. The dwarf species are excellent choices for potted or containerized indoor plants. The majority of larger aloe species can be grown outdoors as landscaping plants or in sizable containers and thrive in full light. Some large species may withstand light frost with minimal or no plant harm. These plants require very little care and attention and are low maintenance.
A sizable genus of succulent plants is called Crassula. Crassula ovata, popularly known as the jade plant, is one of the most popular (also known as money tree, lucky plant, or friendship tree). They are indigenous to Mozambique and South Africa. There are evergreen jade plants. These plants are distinguished by their opposite-pair, thick, meaty, shiny, smooth leaves. Dark jade green in the shade to scarlet on the edges when exposed to direct or full sunshine, are the colors of the leaves. Some variants (known as Crassula Ovata or Hummel’s Sunset) have leaves with a bright yellow-green tint. With time, their branches become thicker.
Jade plants are adaptable and require little upkeep. They can survive in a variety of lighting situations. Once adapted, they may thrive in direct sunlight. When exposed to direct sunlight, their leaves take on a scarlet hue, especially near the tips.
This little pine tree-like succulent, which is native to South Africa, has thin, elongated green leaves and brown stems and bark that can reach a height of three feet. They develop into shrubs and eventually resemble trees. At the tips of the shrub, they produce little white blooms. They should be shielded from the full sun’s glare since they are susceptible to sunburn. These are among the simplest plants to grow from stem cuttings and require very little upkeep. I have many of these plants in various planters that were grown from stem cuttings. My initial plant, which is a few years old, is still alive and well.
This resilient, low-maintenance plant is indigenous to South Africa and is very simple to grow. They can grow up to 20 feet tall and are a source of food for elephants in their natural habitat. They feature glossy green leaves and begin as tiny bushes before becoming tree-like in size. As the plant becomes older, the stem thickens.
I was initially drawn to this plant since I mistakenly believed I was purchasing a miniature jade plant. It has no connection to the actual jade plant, yet it is occasionally referred to as “Dwarf Jade” or “Miniature Jade.” These plants may survive in a variety of environments and are relatively simple to maintain. I have this plant growing in various planters thanks to stem cuttings I used. This plant frequently serves as filler in various arrangements. My original plant is several years old and has endured situations such as neglect.
A hybrid aeonium called “Blushing Beauty” was created by mating two distinct aeoniums. I have discovered that this aeonium is incredibly simple to cultivate and spread. I have a few of these plants that are all stem cuttings that are growing quickly.
Aeoniums are tough, cold-tolerant plants. They thrive in either full sun or little shade. In extremely hot and dry weather, aeoniums go dormant. To reduce excessive water loss, their leaves will curl and fall. The winter or spring is when they experience their true growth. Both containers and the ground can be used to grow them.
These succulents, which are native to Madagascar, are very adaptable to many growth conditions. They can reach heights of up to two feet and are prized for the typically red, pink, or white flowers they produce. These plants have half-inch-long, vicious thorns all over them. The plant is known by the moniker “Crown of Thorns,” which is derived from the biblical account of Christ’s crucifixion and refers to the fake crown that was put on Jesus’ head during the crucifixion. They can be cultivated in either full sun or shade. These are hardy plants that are difficult to eradicate.
This plant, which is indigenous to South Africa, initially has an aloe plant appearance. In reality, they belong to the same subfamily. They have thick, pointy leaves with white stripes that resemble zebra stripes and look warty. They can endure various lighting conditions and can be cultivated indoors or outdoors.
At initially, they grow slowly, but once established, they can develop quickly and produce pups and offsets. I’ve been cultivating mine outside all year. It is one of the easiest plants to care for and has generated a lot of pups and offshoots. Variegated zebra plants have white ridges and horizontal bands of yellow and green hue on their leaves.
These fascinating and unusual-looking plants, also known as Bryophyllum Daigremontianum (also known as Mother of Thousands, Alligator Plant, and Mexican Hat Plant), have enormous green leaves that develop into baby plantlets along the edges. Because of their quick growth and propensity to spread wherever they land, these plantlets have earned the moniker “Mother of Thousands.” They can also be challenging to eradicate.
Once established, these plants are hardy and able to withstand extreme heat. This is the kind of plant to attempt if you’re seeking for one that spreads readily. They can easily spiral out of control, so use caution. Some people find these plants to be bothersome, and some places consider them to be invasive weeds. Grow them in pots or other containers and apart from other plants or the ground to restrict their development.
