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.
How can I keep my succulent plants safe during winter?
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.
Succulents can they endure the cold inside?
Once you understand what they require, it is possible and not difficult to keep succulents alive throughout the winter. If you live somewhere with chilly winters, the best way to ensure that soft succulents survive is to overwinter them indoors. For the most, it will be within their homes, though it could also be a heated building or greenhouse.
Can succulents survive the cold outdoors?
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 indoor succulents be watered?
Don’t overwater the plants. Succulents don’t require as much water in the winter because they don’t actively grow—once every four to six weeks should be sufficient. Use the same method you would in other seasons when you do water your succulents: soak the roots completely, then drain the excess water from the bottom of the pot.
In the winter, how frequently should I water a succulent?
During the months that are not winter, when the temperature is above 40 degrees, you should water your succulents every other week. You should only water your succulent once a month in the winter (when the temperature falls below 40 degrees), as it goes dormant at this period.
A few situations constitute an exception to this rule. Because their tiny leaves can’t hold as much water as other varieties with larger leaves, some varieties of succulents need to be watered more frequently. In the non-winter months, feel free to give these small leaf succulents a water if they appear to be thirsty. When they are thirsty, succulents generally exhibit a wrinkled appearance. But always keep in mind that being underwater is preferable to being overwater.
How are succulents maintained indoors?
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. Succulents should be irrigated if their soil dries completely during the growing season, but excess water should be avoided. When a succulent’s roots have time to dry out in between waterings, its lifespan is increased. 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. Make sure your plants are periodically checked for gnats or mealy pests. These insects are a sign that your plants are receiving too much water or fertilizer. 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.
I have succulents, when should I bring them inside?
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).
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 severe 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.
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.
