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.

Succulents should be taken indoors when?
When you should bring your succulents indoors depends on a few different factors. These elements include your residence and the crops you raise.
Generally speaking, succulents need to be moved inside before the first frost. Typically, this occurs at the end of September.
Bring your succulents indoors when the weather starts to cool down if you live in a hotter climate.
When nightly lows fall below 50 degrees Fahrenheit and daytime highs do not consistently reach 80 degrees Fahrenheit for a few days, it is time to bring them inside.
Typically, this is the time when they start to feel chilly and show symptoms of stress or illness, such as shriveled growths or falling leaves (especially if this has happened before).
Some species, such rosette forms, can tolerate colder wintertime temperatures, but the majority of species require warmer conditions year-round—at least 50 degrees F.
Any tropical kinds growing outside will need to be moved inside when the overnight lows reach the 40s.
When it starts getting darker earlier in the day, that is another consideration when deciding when to bring succulents indoors.
If your days are still long and sunny, it won’t be essential to bring them inside just yet. However, this becomes necessary when nightfall arrives earlier than anticipated (before sunset).
Which Succulents Need To Be Brought Inside During Winter?
Based on how well they tolerate cold temperatures, succulents can be split into two groups: cold hardy succulents and soft or fragile succulent plants.
The only succulents that can tolerate frost when the temperature drops below a particular level are cold hardy (deciduous) succulents. When the temperature is between 20 and 25 degrees Fahrenheit, these succulents can remain outside all winter (-28.88C).
Some cold-tolerant succulent plants may not be able to tolerate dry indoor heating when brought inside for the winter, and they may become dehydrated.
Tropical or subtropical species known as tender succulents must be brought indoors during the winter months because they cannot tolerate frost below a particular temperature.
When it is at least 50 to 60 F outside, soft succulents can be kept (28.88C).
How cold should it be 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.
For the winter, should I move my succulents inside?
Each summer, soft succulents can enjoy some sunshine outside, but they must return indoors before it becomes too cold. Pay attention to the light, air, soil, and water conditions as you bring your plants indoors for the winter.
Light
Naturally, indoor places receive less sunlight, especially during the winter. Sun-loving succulents should be placed close to a sunny window. To stop the pots from fading and straining, rotate them frequently. Add a grow light to rooms that don’t get enough natural light, or try indoor succulent varieties. For rooms with particularly low light levels, we suggest Haworthia, Jade, and Gasteria.
When should you bring in outside succulents?
Before anything else, when is it too early to plant new succulents outside?
In general, waiting until after the last frost and when the nights don’t get below 40F is advised. Even while you could grow certain succulents outside before then, planting is most successful in warmer climates.
However, avoid waiting until the summer because the heat can be just as problematic as the cold. When planting your succulents outside, look for temperatures between 50 and 70 degrees Fahrenheit.
How should I care for my succulents over the winter?
Making sure succulents receive adequate sunshine indoors, especially during the winter, is one of the most challenging aspects of indoor succulent gardening.
Your succulents should be placed next to the room’s brightest window. The ideal window will receive all-day, brilliant indirect light.
This is crucial because the days are shorter in the winter. To retain their shape inside, succulents require at least 8 hours of bright, indirect sunlight each day.
Your succulents may start to spread out or lean toward the window during the winter months when there are a lot of gray or cloudy days. They aren’t getting enough light, as evidenced by this.
You can rotate your succulents in this situation to help correct any leaning. However, you will need to supplement with a grow light to avoid stretching.
Make sure the lights aren’t on all the time because succulents require darkness at night to complete their normal growth cycle.
At the conclusion of the winter, you can take off the tops and propagate any succulents that do start to stretch out or get tall and lanky. After that, you’ll have an abundance of summertime plants!
This is best done in the spring because most succulents don’t grow as quickly throughout the winter. Check out my post on extending succulents for more information on how to achieve this.
Do succulents favor the indoors or outdoors?
Succulents, however, are hardy plants that may thrive in a variety of conditions, including neglect, little access to water, fast-draining soil, and a steady source of sunshine.
It’s excellent if you live somewhere where the weather is just right for them to thrive outside.
But if you don’t, you’ll need to make some alterations and adjustments.
These bizarre plants have evolved to survive in the worst conditions, including the wettest climates, little to no soil, and the steepest slopes.
A variety of surprises, including vibrant edges, tips, or complete shifts in foliage color, can be found in the sunlight or the chilly outdoors.
When succulents are grown outside, the weather will determine and set off when the plants are dormant or active, depending on the species. On the other hand, when it warms up, that can cause new births, color changes, or blooming.
Can succulents be kept indoors?
Succulents thrive in hot, arid conditions and don’t mind a little neglect due to their unique capacity to store water. They are therefore ideally suited to growing indoors and are the perfect choice for anyone looking for low-maintenance houseplants. Follow these instructions for successful plant care if you’re choosing succulents for the first time.
Select a succulent that will thrive in your indoor environment.
The majority of succulents need direct sunshine, however if your home only has a shady area, choose low light-tolerant plants like mother-in-tongue. law’s A trailing variety, like string of bananas, is an excellent option if you intend to grow your succulent in a hanging planter. To learn about your succulents’ requirements for sunlight, size, and spread, always read the plant labels.
Give the plants a good draining potting material.
You should repot your succulent as soon as you get it home since nurseries always plant their succulents in soil that is overly rich and holds too much moisture. A coarse potting mix with sufficient drainage and aeration is a good place to start. You can use an African violet mix or unique cactus and succulent mixtures that you can purchase at the nursery. Add perlite or pumice to the cactus or African violet mix (up to 50% of the total potting mix, depending on your particular succulent’s moisture requirements) to further increase drainage and prevent compaction. To make sure the mixture is moist throughout, always moisten it before using.
Decide on a container.
When repotting, use a container that is at least 1 to 2 inches bigger than the nursery container and has a drainage hole. Avoid using glass containers (such mason jars or terrariums) for long-term potting since they prevent roots from breathing and over time may result in root rot. Place your plant inside the container and backfill with extra pre-moistened potting mix after filling the bottom one-third of the container with pre-moistened potting mix.
Put the succulent plant in a pot somewhere sunny.
Try to arrange your succulents close to a south or east-facing window because most succulents need at least six hours of sun each day. Insufficient sunlight may cause your succulents to become spindly or to extend toward the light.
Between waterings, allow the potting mix to dry out.
Overwatering succulents is the most common error people make with them. Watering more deeply but less frequently is preferable. Before the next watering, completely saturate the potting mix (while making sure the water drains out of the drainage hole properly). The plant can finally perish if the potting soil is left moist every day.
Succulents should be fertilized at least once a year.
Fertilizer works best for plants in the spring (when the days lengthen and new growth starts) and again in the late summer. Use a water-soluble, balanced fertilizer (such as 8-8-8 or 10-10-10) that has been diluted to half the strength indicated on the container. Since succulents are semi-dormant in the winter, there is no need to nourish them. Because they are not actively growing, they do not require the nutrient boost.
Do succulents require sunlight?
Depending on the type, succulents need six hours of sunlight each day because they are light-loving plants. You might need to gradually expose newly planted succulents to full sun exposure or give shade with a translucent screen because they can burn in direct sunshine.
The Effects of Temperature on Succulents and Cacti
Succulents and cacti prefer to reside in the “sweet spot” of temperature, just as is the case with sunlight exposure. These hardy plants can suffer irreparable harm from either extreme of the temperature range, so it’s important to monitor their health and adjust the environment as necessary.
Succulents and cacti thrive most effectively in temperatures between 40 and 80 °F. Outside of this range, little temperature swings are tolerated, but swings of five or more can result in permanent harm. Even more intriguing is the fact that temperatures that are on the edge of the bearable range (about 40°F or 80°F) can operate as “stressors,” positively affecting the plant and encouraging the expression of more vivid hues.
Succulents and cacti should ideally be kept above freezing during the winter to prevent frost damage. While more tropical types like euphorbia and lithops demand minimum temperatures of 50 to 60 degrees Fahrenheit, other cultivars are actually frost hardy and prefer cooler overnight temperatures of 30 to 40 degrees. Searching for “ideal temperature for insert plant name here” on Google is currently the quickest approach to find out what temps are optimal for your plants. Each plant product page will eventually feature our own documentation.
Extreme Cold and Extreme Hot
Succulents and cactus can, you guessed it, freeze when exposed to freezing or below-zero weather! The water that has frozen inside the plant’s cells expands as it thaws, killing the cells by rupturing them. When the plant finally thaws out, the damaged regions will start to decay or scar permanently—a symptom that could take a few days to manifest. To stop the rot from spreading, the best course of action in this circumstance is to remove the afflicted region with a clean razor blade.
It is preferable to relocate your collection under a patio cover or inside of your home while the freezing conditions last in order to prevent damage from frost and freezing temperatures temporarily. A “frost blanket,” which is just a thin piece of fabric designed to protect plants from cold, can also be used to cover your plants. Plants should be taken indoors for the winter or placed in a sunroom or greenhouse with plenty of natural light in regions of the country where cold temperatures last for months at a time (essentially everywhere else save California).
However, heated temperatures can also do harm if they are not controlled, so they are not the only bad guys in this tale. A variety of things can happen to your plants when it becomes too hot (90 degrees Fahrenheit and above), especially when combined with full sun exposure. For example, leaves may shrivel and/or burn, water inside plant cells may steam and explode, and root systems may become fried.
Because soil is not a very good conductor of heat or cold, succulents planted in the ground with developed root systems can withstand high heat and cold more better than those planted in containers. On the other hand, containers easily conduct heat and cold, focusing such extremes on the roots of the plants.
There are always exceptions to the norm, just like there are in everything else in life. Succulents can withstand temperatures well below freezing and temps as high as 100 degrees. Drive about and observe what sorts of succulents your neighbors are successfully cultivating to find out what varieties work best in your specific climate.
Moisture and Extreme Temperatures = Bad News
Extreme heat and dampness are among the most troublesome environmental conditions. You should never put your plants in a situation where they are both hot and damp or cold and wet. Whether in the ground or in containers, plants that are grown in dry soil perform far better than those that are not. The water in the soil might start to steam in exceptionally hot weather, thus “cooking” your plants. Water can obviously freeze in freezing or subfreezing temperatures, harming the root system and producing rot. If you absolutely must water your plants when extremely high temperatures are predicted, try to do so as early as possible, ideally before 7 a.m.
The TLDR (too long, didn’t read) Summary
Average temperatures are much preferable to harsh ones for succulents. Frost damage can occur in cold conditions, whereas scorching and atrophy can occur in hot temperatures. Paying attention to what your plants are saying is the simplest method to make sure they are content. Bring them indoors or wrap them in a frost blanket if they are suffering from frost damage. Move them to a sheltered spot or cover them with shade cloth if they are scorching or wilting.
