When Is It Too Cold For 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 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.

Are succulents too cool for 50 degrees?

You might be curious about the lowest temperature at which succulents cannot survive when taking care of them. Warm, arid regions are where these plants are native. Nevertheless, while some succulents can endure colder temperatures, others cannot. What degree of cold is therefore too much for your succulent?

Any temperature below 50 degrees Fahrenheit is too chilly for succulents, which typically require temps between 50 and 80 degrees Fahrenheit. Depending on the species, a succulent’s lowest temperature tolerance varies.

I have succulents, when should I cover them?

“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 succulents endure temperatures of 30 degrees?

Succulents can be difficult to cultivate outdoors in the winter in colder locations. There are still certain succulent plants that thrive in snowy conditions, despite the fact that they are generally known for preferring sunlight and not the other way around. Three of the most cold-hardy genera are Sempervivum, Hardy Sedum, and Hardy Opuntia, which can withstand subfreezing winter temperatures of -30F. Agave and rosularia are two other succulents with high cold tolerance.

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 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.

My succulents are outside, is that okay?

Succulents are drought-tolerant plants because they can retain water in their large, irregularly shaped leaves. Succulents have a broad variety of eye-catching shapes and textures, which provide any landscape aesthetic interest. Can succulents live outside? is an often asked question. The quick response is “yes”! Growing succulents outdoors is an excellent alternative because they do well there and can withstand some neglect. They also do well in sunny areas with warm, dry weather.

Succulents can be grown in the ground, in pots, or hidden in unexpected planting locations. Take the uncertainty out of caring for these wonderful conversation pieces with stunning foliage by reading our suggestions for growing succulents outside.

Should succulents be protected from the cold?

Knowing how to protect succulent plants from frost is crucial now that the weather is turning colder and I’ve added them to my garden containers. Perennial plants typically die to the ground in response to winter cold. Their roots produce new growth in the spring. However, many succulents native to warm climes lack this adaption and necessitate special care when planted in areas where the temperature falls below 32 degrees Fahrenheit.

Debra Lee Baldwin, a talented photojournalist and author, has some advice for you. — Avoid removing the dried leaves that are affixed to a succulent’s stem or trunk. They safeguard it from harsh temperatures (cold and hot). Keep succulent plants as dry as possible. When the liquid inside of turgid cells freezes, they are more likely to explode. — Move succulent plants in pots under a deck, a tree, or the eaves. (I attempt to conceal them in places that are covered adjacent to the home)

— Position pots near hardscape, stones, shrubs, and/or walls that absorb and gradually release heat from the sun. The best exposures are to the south and west. — Use old bed sheets or frost cloth to cover succulent plants. Avoid plastic, which amplifies sunlight, retains moisture, and prevents plants from breathing.

If your succulents are damaged by frost, only remove collapsed leaves if it’s likely that they’ll stay damp and decompose. Leave them on, though, and prune in the spring if they will protect the plant from subsequent frost. — Avoid cutting straight across tip-burned leaves on slender-leaved succulents (like agaves and aloes) in order to preserve their geometric shape. — Just put it down to experience. Now that you are aware, you can find a safe place for that specific plant. (I’m attempting to get better at gardening and have joined the Solano Master Gardener program.)

How can I keep my succulent plants in pots safe this 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.

Do succulents require indoor space in the winter?

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 toward 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 neighborhood 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 neighbors the information so they can preserve their succulent plants as well!
