Yes, it is the answer. Although certain succulents can withstand frost, they are frequently thought of as drought-tolerant plants. They flourish in chilly, snowy conditions, and the extreme cold even brings out their magnificent, vivid colours. They are referred to as “Hard Succulents.” Sempervivum, Sedum, and Euphorbias genera contain some of the most hardy succulents. You may plant such succulents outside all year round because the majority of them can withstand temperatures as low as -20F (Hardiness Zone 5).
“Soft Succulents” are another group of succulents that are more susceptible to frost. When the weather drops below freezing, they must be winterized inside.
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 shrivelling. 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 centre. 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 fertiliser. 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.
Can you leave succulents outside during the winter?
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.
Can succulents survive the cold indoors?
An area with at least three to four hours of bright light should be chosen for a dormant succulent. In comparison to the summer, when they are actively growing, succulents require less light in the winter. During the winter, succulents can tolerate indirect lighting.
Bring succulents inside before winter temperatures drop below freezing since sudden temperature fluctuations might kill plants. During the winter, keep the room where the succulents are at no lower than 50 degrees Fahrenheit. To allow them to relax throughout the winter, some succulents, like Aeoniums, may fare better in a chilly room or basement, between 50 and 55 degrees Fahrenheit.
Succulents spend the winter somewhere.
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 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.
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 fertiliser.
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.
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.
Succulents can they survive indoors without sunlight?
The most light is reflected from south-facing windows throughout the day in the northern hemisphere. The sun shines through windows facing east in the morning and west in the afternoon and evening. The least quantity of sunlight enters windows that face north.
A south-facing window is the best choice for the majority of sun-loving succulent plants in the northern hemisphere. However, all of the low-light succulents covered in this article happily flourish in windows that face west or east. Even in a dark, north-facing window, some of them will make it, but I don’t advise it because even there, they won’t thrive.
However, no succulent can live in a completely dark environment. Therefore, even if your succulent plants are varieties that thrive in low light, think about buying a tiny desktop grow light if you live in a basement flat, have only a north-facing window, or if your space has no windows at all. When a modest grow lamp is placed over low light succulents for 6 to 8 hours a day, you’ll be astounded at how well they grow. You won’t need to remember to turn the lights on and off every day if you have a reliable timer.
Now that you are aware of how much sunlight low light succulents require, allow me to introduce you to some of the greatest low light succulents.
Succulents do not hibernate inside.
True dormancy is not experienced by succulents cultivated indoors. As a result, you’ll discover that propagating or transplanting succulents indoors throughout the year is not a problem.
Waiting until the succulent is in its active growing season is optimal for succulents growing outside. The spring and fall seasons are often when you’ll see the best effects.
Extremes in temperature will be your main obstacles when transplanting or planting succulents outdoors.
For my sister-in-law in Southern California, I planted several succulents. The succulents were outside in the ground when we planted them in June, but because of the heat wave, they were experiencing temperatures near to 100F. (38C).
These little 2 (5 cm) succulents didn’t have time to adjust to that scorching temperature and the full sun because the place we were putting them in was also in full sunlight. The majority of them perished.
Even cold-hardy varieties of succulents would freeze if I tried to plant them outside in the midst of the winter when I still lived in Utah since they weren’t used to the extremely cold temperatures.
Succulents can, however, be planted all year round provided you give them a beautiful, temperate climate without too many extremes.
Because (shocking, I know…) they are growing more throughout their active growing season, you’ll discover that your succulents take transplanting better. As a result, they will heal more quickly and acclimate to their new surroundings more quickly.
The process of propagating succulents is comparable. In the end, spring or fall, when that particular succulent is beginning its active growing season, are the greatest times of year. The growth of these plants can be propagated at other seasons of the year, but it will often be slower.
Again, this is relevant to succulents grown outside. Succulents grown indoors can be easily reproduced all year long and develop at a similar rate.
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 fertilise. The periodic fertilising is beneficial for even low maintenance desert plants. To give your succulents a boost, use a diluted, water-soluble all-purpose fertiliser a couple times a year. Although it’s not entirely required, if you notice that your soil needs some help, add a little fertiliser.
- 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 fertiliser. 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.
