Since most succulents are accustomed to hot, arid environments, they are particularly hard hit by winter’s frigid temperatures.
Some succulents, like Aloe, Echeveria, and Crassula, require frost protection when the temperature falls below 45 degrees Fahrenheit. The majority of the other species can endure temperatures higher than 40 °F.
No matter the genus, you should never leave your succulents in a freezer. The explanation is straightforward: because succulents hold a lot of water in their leaves, stems, and trunks, when the temperature drops below freezing, the water expands and bursts through the cell membrane. The plant will eventually expire.
The plants can sense fewer days and lower temperatures, which indicate the impending winter. However, by winterizing them, you can deceive your succulent. Before it becomes too cold outside, you can bring the plant inside and give it regular care.
Simply said, the fall is the ideal season to bring succulents inside. You need to keep your plants from detecting the shift in weather conditions, therefore don’t wait until the actual winter.
When it gets cold, should I bring my succulents inside?
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 towards 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 neighbourhood 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 neighbours the information so they can preserve their succulent plants as well!
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.
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 colours for Winter Interest, is one of our favourites. The frost-hardy Sedum cultivars are especially recommended since they create excellent ground covers in practically all regions.
Where do I put my succulents during 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 towards the window during the winter months when there are a lot of grey 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.
Outside, how cold is too cold for succulents?
Because they are fickle plants, succulents shouldn’t be kept in temps so low. Succulents cannot survive in cold climates, so if you see the outside temperature lowering, take immediate action to save succulents from freezing.
It is unlikely that succulents will survive in temperatures below 40 degrees Fahrenheit. Succulents are susceptible to freezing and dying at temperatures between 30 and 40 degrees.
When it gets colder than forty degrees Fahrenheit, succulents should be brought inside. Learn how to take care of your succulent in cold weather, why 40 degrees is the point at which it can no longer survive, and what other temperatures are harmful to these plants by reading on.
Can succulents endure temperatures of 40 degrees?
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.
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 glasshouse 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 neighbours are successfully cultivating to find out what varieties work best in your specific climate.
Moisture and Extreme Temperatures = Bad News
One of the most problematic combinations of environmental conditions is extreme temperatures and moisture. 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.
How are succulents wintered?
Succulents are currently among the most well-liked garden plants, particularly among younger gardeners who are trend-conscious. It makes sense that these plants are now adorning so many patios, porches, and windowsills. They require very little upkeep and can withstand drought. Additionally, several succulent kinds are a wonderful conversation starter due to their unusual appearance.
A group of plants known as succulents have large, water-retentive leaves that are thick and succulent. Jade plants, kalanchoes, hens and chicks, and even aloe vera plants are examples of vintage varieties that you may already be familiar with. However, there are now a large variety of plant forms, leaf hues, and growth behaviours among the hundreds of distinct succulent plants that can be found at your neighbourhood garden centre.
Succulents of the Agave, Crassula, Dudleya, Echeveria, Sedum, Haworthia, and Sempervivum species varieties are some of the most well-liked varieties.
It’s time to consider how to overwinter any succulents you may have grown this year in patio pots or your garden. The plants can be left outside all winter long if the kinds you chose are completely winter hardy in Western Pennsylvania. This group includes hardy chickens and chicks.
However, the vast majority of succulent plants offered for sale these days in garden centres are not hardy in our gardening region. Combining that with the cost of these plants, you’ll probably want to figure out a way to overwinter them so you can use them in your garden the following year as well. Succulent plants can be overwintered in three different methods.
1. Use indoor succulent plants for the winter. On an indoor sunny windowsill, the majority of succulents thrive. The key to successfully overwintering succulents as indoor plants is to drastically reduce their watering requirements. If kept excessively damp, many succulents will actually rot, therefore water succulents used as houseplants throughout the winter just once every six to eight weeks. As you water, take care to keep the leaves dry. Additionally, you should keep the plants in a room that is not overly hot or chilly. Avoid forced air registers and cold draughts.
2. Semi-dormant succulents overwinter. Succulents don’t go into full dormancy, but it is possible to drive them into a semi-dormancy by severely limiting their access to water, drastically reducing their exposure to light, and maintaining them in an environment where the temperature is just above freezing. I raise about 50 succulents and cacti outdoors in my garden throughout the summer and overwinter them in this way.
I relocate my succulent pots into our linked, but unheated garage when the low 50s are reached at night. The garage has two modest windows. The pots are arranged along the garage’s sidewalls, and I neglect them the entire winter. I don’t fertilise or water the plants. They enter a semi-dormant phase where no active growth takes place.
I move the pots outside on warm days in mid- to late-March and lightly water them, taking care to keep the foliage dry. When the threat of frost has gone in mid-May, I move the pots back into the garage once they have drained and put them back up on my patio.
3. Use cuttings to overwinter succulents. Taking cuttings of your succulent plants is another approach to ensure that they survive the winter without harm. The majority of succulents are simple to grow from leaf cuttings. Fill several tidy plastic pots with a coarse, cacti-specific potting soil to accomplish this. With a sharp knife, remove a single leaf off the mother plant. Dip the cut end of the leaf into rooting hormone (which is sold at nearby garden centres or online), and then press the cut end of the leaf down into the pot of soil by about a half-inch. The pot or leaf cutting should not be covered, but it should be watered in at planting time and any other time the soil feels fully dry.
At the base of the clipped leaf, a new plantlet will emerge in a matter of weeks. Eventually, the old leaf will wither away, leaving only the new plant. If you want to grow your succulent collection over the winter, take lots of cuttings. Keep your succulent cuttings out of direct sunlight, but on a sunny windowsill. Another choice is to place them 18 to 20 hours per day in grow lamps. As long as you don’t overwater succulents, taking leaf cuttings from them is quite easy.
