Succulents can withstand both heat and cold. A succulent can survive in temperatures as low as 40 degrees Fahrenheit, much like the desert, which can have chilly nights.
THE IMPACT OF TEMPERATURES ON SUCCULENTS
Succulents typically prefer climates with temperatures between 60 and 80 °F. Some people can withstand temperatures as high as 90°F or as low as 40°F. These extreme temperatures are occasionally used by gardeners to “stress” their succulents into changing color. Many succulents, especially soft succulents, can often benefit from high temperatures between 80°F and 90°F to keep their beautiful hues. You’ll notice that many hues will start to get more intense when the temps fall (but remain over 40F). The chilly (but not freezing) temperatures over a prolonged period of time intensify these colors. Be mindful that your succulents can suffer from temperatures that are too high or too low. Never recommend a temperature of 40°F or greater than 90°F.
Your succulents may suffer from sunburn in the summer due to the combination of high temperatures and direct sunlight, which can harm both the leaves and the root systems. You should move your succulents to a shaded place during the warmest part of the day or cover them with shade cloth. People who reside in regions with extremely hot climates might think about planting their succulents directly into the ground as opposed to in containers since soil temperatures remain largely stable regardless of fluctuations in the weather. If you want to grow succulents in containers, pick materials like concrete, terracotta, ceramic, or wood that are excellent at protecting plants from rapid temperature changes. Avoid using metal and glass containers.
Keep the temperature above freezing to prevent frost damage to your succulents over the winter. You can do this by covering them with a cloth or bringing them inside. While some tropical species like Euphorbia and Lithops demand temperatures of at least 50-60F, some cold-hardy species, like Sempervivum, can endure frost and love cool temps from 30 to 40F. Check out the Hardiness information on each of our plant product pages, where we provide thorough information on the USDA Hardiness Zone for each plant, to discover precisely whether a certain succulent variety is suitable for the climate in your location.
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.
When is the best time to bring indoor succulents?
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.

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.
In the winter, should you cover 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.
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!
Is it possible to hydrate succulents with ice cubes?
One of the most enjoyable pastimes you can engage in is caring for plants. They will not only give you many advantages, but they are also aesthetically beautiful. Simply ensure that you are aware of how to care for them.
Be mindful of the risks if you decide to attempt watering succulents with ice cubes. It’s conceivable that your plants will be harmed or killed if you subject them to such jarring temperature variations.
Any plant won’t like having its watered with ice cubes, succulent or not. To avoid stressing them out, it is preferable to use room temperature water. Additionally, you should plant plants in containers that encourage proper water drainage as well as good air circulation.
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.
