if your succulents had previously experienced cold damage. Now, what do you do?
The first step is to relocate them somewhere warm to prevent further exposure to the subzero temperatures.
Next, let them to dry out for many days or even weeks, depending on how badly they were frostbitten. All of the mushy frostbite lesions should be allowed to dry up and scab over. Your succulent will be operating in emergency mode as it attempts to stop additional harm.
Your succulent is more likely to rot and die if you water it too soon after it develops frostbite.
If you can, clip off the frostbitten parts once they have dried out. This may require you to remove significant portions of the plant. Sometimes, you might only be trimming the ends.
For instance, the ends of a fragile Aloe or Agave plant may become dry. In that instance, you may simply trim the leaf so that it resembles a typical Agave or Aloe leaf while also removing the dried-out and crispy portions.
The center of your succulent plant is typically unaffected by frostbite, which typically affects the plant’s outer edges first. In a way, this is the “best case situation” that you would hope for.
It’s likely that the succulent won’t be able to be salvaged if the frostbite extends into the stem. Your succulent is more likely to survive if you cut off and clean out any damaged areas of the plant.
Wait another two to three days before watering once you’ve clipped off the damaged areas. You should allow enough time for these wounds to callus over and heal.
Then, when everything is once more dry, you can begin watering your succulent. To promote healthy root growth, make sure you’re employing the soak and dry technique I recommend.
It’s crucial to understand that the damaged sections of your succulents you’ve plucked won’t regrow. However, if everything goes as planned, the new growth on your succulent should be strong and appear natural.
The succulent will need some time to recover its stunning appearance, but as with most succulent gardening, your persistence will be rewarded. As your succulent grows over the coming weeks and months, it will begin to resemble its former, joyful self once more.
Make sure the succulent is covered from cold, as well as from intense heat or sunlight, when you put it back outside (or in the spot it was growing). You need to gradually reintroduce your succulent to the growing circumstances it was accustomed to before it was in a protected area.
Also problematic is shocking your succulent with abrupt changes in temperature or light.
Do succulents recover from freezing?
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.
A succulent can it endure being frozen?
“Frost tender” succulents may experience variable degrees of damage, depending on how long the temperature is below freezing (32 degrees F). A sensitive plant’s cells expand, burst, and transform its leaves to mush when liquid inside them freezes. In a “light frost,” only the tips of the leaves may be harmed (“frost burn”). A “hard frost” is characterized by sustained temperatures below freezing, which can cause entire plants to die. Typically, succulents do not recover from roots.
Ones that are among the most fragile succulents include crassulas, aeoniums, euphorbias, and kalanchoes. Some succulents, in particular, have an inbuilt antifreeze that allows them to endure temperatures considerably below 32 degrees Fahrenheit—in fact, below zero.
Are your outdoor succulents at risk over the winter? Depending on where you reside, Please refer to “Cold Weather Care for Outdoor Succulents, By Region.”
Your area is frost-free (lucky you!) if…
This soft-leaved agave in my garden is the canary in the mineshaft when it comes to cold. Many succulents may survive a brief cold (less than an hour), but Agave attenuata’s leaf tips immediately reveal damage.
Although ugly, this damage rarely results in death. See how each leaf’s healthy green portion is? Cut each leaf to a point using scissors to remove the tissue-paper-like frozen tips. The harm won’t be very evident when you’re finished. Those shorter, clipped leaves will be buried by new growth during the summer. (Note: Such damage is comparable to scorching brought on by excessive sun and heat, which is common of desert conditions, and by wildfire, which, believe it or not, does occur.)
What about a succulent or agave that only suffers damage from frost on the tips of its leaves? Don’t even try trimming them. In a few months, it will shed those oldest leaves nevertheless.
areas with sporadic, light frosts (like Southern California’s interior):
If there is a “frost advisory” for your area, keep an eye on the weather forecast, and before it gets dark, go outdoors and cover your sensitive succulents. After midnight, frost is more common, and temperatures increase colder as dawn approaches. Warm air is lighter than cold air, which travels down hills and gathers in low areas. Succulents in swales are therefore more vulnerable than those on top of berms. You may have heard that Christmas lights slightly increase the temperature. Yes, if they are the traditional variety. LEDs in current use don’t produce heat. You should be concerned about succulents that are exposed to the elements and have nothing over them. I occasionally lean over a succulent and look up. It becomes draped if there aren’t any tree limbs or eaves directly above.
I reside at 1,500 feet in the foothills NE of San Diego (Zone 9b). And yes, after seeing the weather forecast on the late-night news, I have been outside at 11 p.m. in my pajamas and slippers, freezing while I place blankets on delicate plants while my husband holds a flashlight. I may leave the plants covered if several nights of frost are expected; otherwise, I take the sheets off the next morning. I fasten them with clothes pins and rocks to make sure they won’t blow off. AVOID using plastic. The plants are unable to breathe because of it.

Why cold damages some succulents and not others
The origin of a certain plant type affects it greatly. Most succulents are native to dry, hot areas where they can store water in their leaves to survive drought. The ones that don’t freeze, however, are from dry, cold climates. See my essay, Showy Succulents for Snowy Climates, in the Wall Street Journal. The “hardies” include:
several species and cultivars of sempervivums (hens-and-chicks, above); some cactus, yuccas, and agaves (such as Agave utahensis, A. montana, and A. parryi); and lewisias from the Pacific Northwest.
Can frost-damaged succulents be revived?
If no tissues are harmed, you can preserve your succulents if they have frostbite. You won’t know the full amount of the damage for a week or two. If you see any new growth at the base, the succulent may be able to be revived.
Can you thaw out a frozen plant?
You can perform a few crucial things to help resuscitate your frozen plants if they appear to be dead. Start by continuing to water your frozen plants. Any plant needs water to stay healthy all year long. You might also try giving the plant an enhancer. This can occasionally deceive the plant into growing again.
Recall to wait. To see what happens, give your plants at least another two weeks. When necessary, keep covering them, and take the usual precautions to ensure their survival.
What does succulent cold damage resemble?
Most succulents commonly suffer frost damage in really cold weather. It often happens when ice crystals build inside of their tissue, harming their cells. When that occurs, you’ll start to see some signs of frost damage, like drooping leaves on your succulents, which will eventually turn brown or black and get crispy. In other words, your succulent plants are currently slowly dying.
There is still hope, nevertheless, if there are some remaining healthy leaves or even viable leaf fragments with frozen tips.
Treatment
Don’t prune immediately. Wait till it warms up outside or until the plant starts to produce new leaves. Once it is certain that there is new growth at the root, use clean, sharp scissors to carefully remove the afflicted areas. Using clean scissors will help stop bacteria from further hurting your plants.
Refuse to water. Plants that have just been pruned shouldn’t be watered right away. Your fragile succulents may experience shock if you water them too soon. Before watering the cuttings, wait until they are entirely calloused over. When they do, water your plant thoroughly once every two weeks.
- Avoid areas that receive direct sunlight. It should be sufficient to just set your succulents on a sunny windowsill. Depending on your climate zone, direct sunlight might still harm or burn you even though it is weaker in the winter. Your plants will be able to cure themselves with just a little bit of partial or filtered sunshine.
- Wait tolerantly. Usually, a few weeks after the plant has been trimmed, part of the leaves will die and drop off. Do not panic if you see the leaves beginning to wilt. Your succulent will eventually heal as new leaves begin to emerge from the center.
Precautionary measures
- Prevent pruning in the early or late fall. Pruning encourages the formation of new growths, such as leaves or offshoots, hence avoiding it helps prevent this. They would struggle to survive in the intense cold, so your succulent would have to work harder to attempt to develop as they were working to heal.
- Water the ground well. As wet soil maintains heat better than dry soil, doing this will assist warm the air close to the soil and save your plant’s roots.
- To protect them, cover them. To protect any delicate plants, you can simply wrap them in blankets or another warm material. Just remember to uncover them the following day when the temperature rises, as leaving them covered could lead them to wilt.
- Place a grow light near your succulents. A average grow light will be between 35 and 40 watts, which should be adequate to keep your plants healthy during the winter.
- Use a spray anti-perspirant. These sprays aid in preventing moisture loss in plants. The anti-transpirants offer a clear, flexible protective layer to stop moisture loss during winter’s typically crisp, dry winds. It won’t obstruct the osmosis, photosynthesis, or organic growth of your succulent. To keep moisture in the foliage of delicate plants, apply it there.
- If your plants must stay outside, group them in containers that are close to one another and place them in a protected spot that is easy to access, like your patio, so you can take care of them and keep them alive and healthy.
How can frozen plants be saved?
Watering your cold-shocked plants is actually beneficial, despite what might seem paradoxical. They can overcome the stress and trauma with the aid of water. Give your damaged plants a little water, maybe an inch or so. When a plant freezes, moisture is drawn out of its tissues.
What signs do plants have after a freeze?
Winter temperatures that plunge often cause plant damage from frost. Ice crystals that grow inside plant tissue harm the cells, causing damage. The first things typically harmed are leaves and fragile new growth. They will initially seem withered. The wilting growth will eventually get crispy after turning brown or black. This indicates that the afflicted plant portions have passed away.
Although it may be tempting to remove frost-damaged plant growth right away, dead material has to stay on the plant until the full amount of the damage is seen in the spring. There are many good reasons to hold off. It will be much easier to determine the degree of any damage and less likely that you will unintentionally destroy living tissue that withstood a freeze if you give plenty of time for new development to appear. Dead tissue can also act as insulation, thus removing it too quickly could expose adjacent tissues to further freezes. It is more likely that a larger percentage of the plant will die if you remove dead growth before another freeze. It is wise to hold off on any pruning until at least late April, or later, when the danger of frost is typically past in Chico and the surrounding areas of the valley bottom.
How may cold shock be prevented in plants?
All of your current efforts will be focused on reducing the harm. Checking the weather prediction should be done first. Was this cold spell a one-night stand, or may temperatures at night continue to decrease for a few days? If it happened in one night, your recuperation will be your top priority. Your efforts will need to focus on averting additional harm if this cold weather is likely to last, including
- Sprout the Plant Watering the plants that are damaged should be done first. Your plant will be able to recover with an inch of water.
- Don’t Fertilize
- During this period, avoid fertilizing your plants. Fertilizing can promote new growth, which adds stress to a plant that is already under stress from trying to recover. Additionally, any delicate new growth will be extremely vulnerable to cold harm.
- Don’t prune
- Although you might be tempted, resist the urge to cut off the damaged portions. Till the weather warms up and the new buds appear to indicate where the dead tissue begins and ends, let your plant recuperate. When a plant is in cold shock, heavy pruning can cause further stress and may even promote new growth when the plant should be putting all of its energy into recovering. A soft tissue plant with patches of black or mushy stems or leaves is the exception to this rule. If left on the plant, this rot will spread to healthy regions.
- Bring indoors pots
- You could believe that bringing your affected plants inside the home is best for them if they are in pots. Your plants may also become stressed by the abrupt temperature change from the chilly outside to the warm inside. First, get them inside the garage that isn’t warm. They will be shielded from additional cold harm and given time to adjust to the warmer temps. Bring them inside a cool room of your house after a few days.
- Shelter and a Group
- If you are unable to bring the potted perennial plants inside, try to arrange them together in a protected spot. The plants will be grouped together to protect one another from the cold. You’ll find it easy to add more plant protection from the chilly temps if you group them together.
- Repot after trimming dead roots
- The sad indication of significant damage can be a loose root ball in its planter. By taking the plant from the pot and removing any evident dead roots, you might try to rescue it. Repot your plant in new potting soil after that, and water it lightly. Your plant might live if enough of the root system is unharmed.
- Utilize sunlight from a windowsill.
- As was previously noted, indoor plants are susceptible to cold shock. The cold from outside can be to blame if you’ve put your brightly flowering amaryllis bulbs or houseplants on the windowsill to give them the most sunlight possible. To test how chilly it is, place your hand against the window. The issue could arise if the leaves come into touch with the glass. If the window doesn’t seal properly, a draft from the chilly air may be harming your plants. Reposition the plants so they are farther away from the window so they may still enjoy the sunlight without being exposed to the chilly glass or drafts.
