Now that Winter is upon us, you may be asking “How cold is too cold for succulents”.

Succulents, with their diverse array of species, have captured the hearts of plant and garden enthusiasts worldwide.

Yet, a common concern among succulent lovers is understanding the delicate balance of temperatures that these resilient plants can endure. 


In this blog post, we’ll explore the nuanced relationship between succulents and cold temperatures.

With this information, you will know how to determine when it’s too cold for certain types of succulents.

Soft vs. Cold-Hardy Succulents

Succulent enthusiasts are well aware that there is no universal standard when it comes to the cold hardiness of these plants. 

Soft succulents, such as the elegant Echeverias and Aeoniums, exhibit a higher sensitivity to colder temperatures.

For these tender varieties, temperatures below 32 degrees Fahrenheit (0 degrees Celsius) are generally considered too cold, risking frost damage and a loss of vibrancy.

On the other hand, cold-hardy succulents, including stalwarts like Sedums and Sempervivums, are equipped to handle lower temperatures with greater resilience. 

Some of these hardy varieties can endure temperatures as low as -20 degrees Fahrenheit (-29 degrees Celsius) or even cooler temperatures, depending on the type of succulents.

Understanding the classification of your succulents is crucial in determining their cold tolerance.

Cold Hardy Succulents


Cold-hardy succulents refers to a group of succulent plant varieties that have developed natural adaptations to withstand and thrive in colder climates. This includes regions with freezing temperatures and harsh winter conditions. 

These succulents are equipped to endure low temperatures that might be detrimental to more tender or soft succulent varieties.

Here are some examples of popular cold-hardy succulents that can stay outdoors year-round.

1. Sempervivum (Hens and Chicks)

Sempervivums are well-known for their rosette-shaped clusters and are among the most cold-tolerant succulents. They can endure freezing temperatures and are often found in rock gardens or as ground cover in colder regions.


2. Sedum (Stonecrop)

Sedums are a diverse genus of plants that includes many cold-hardy varieties. They come in various shapes and sizes, with some being ground covers, while others are taller and more upright.

Sedums are known for their ability to thrive in chilly climates.

3. Jovibarba

Similar to Sempervivum, Jovibarba, commonly known as “Rollers” or “Hen and Chickens,” is another cold-hardy succulent that forms tight rosette clusters.

They can withstand freezing temperatures and are often used in alpine or rock gardens.

4. Opuntia (Prickly Pear Cactus)

While many people associate cactus plants with hot and arid climates, certain species of Opuntia, such as the Prickly Pear Cactus, are surprisingly cold-hardy.

They can tolerate a light frost and are known for their distinctive pad-like structure.

5. Agave

While some Agave species are more suited to warm climates, certain varieties, such as Agave parryi, Agave neomexicana, and Agave utahensis, are considered cold-hardy and can withstand colder temperatures.

6. Delosperma (Ice Plant)

Delosperma, commonly known as Ice Plant, is a cold-hardy succulent ground cover with vibrant, daisy-like flowers. It’s well-suited for gardens in colder climates and is known for its ability to spread and create a colorful carpet.

In short, these plants are valuable additions to gardens in regions with challenging winter conditions.

Their ability to endure frost, snow, and freezing temperatures makes them resilient choices for outdoor landscaping in colder climates.


Minimum Temperatures and Microclimates

To safeguard your succulents against colder climates, it’s essential to consider the minimum temperature each species can tolerate.

Referencing the USDA Hardiness Zone map provides valuable insights, matching your location with the recommended cold hardiness of your succulents.

Additionally, within your garden or outdoor space, be mindful of microclimates.

Certain areas may be more prone to colder temperatures. This is especially true with low-lying spots where cold air settles.

Strategic placement of your succulents helps minimize exposure to potentially damaging cold air.

What Cold Elements to Avoid with succulents

Succulents, while resilient, can face challenges when exposed to certain cold elements.

To ensure the health and well-being of your plants, it’s crucial to be vigilant and watch for the following cold-related factors:

1. Freezing Temperatures

Succulent plants vary in their cold tolerance, with some able to withstand freezing temperatures and others more sensitive.

Watch for forecasts predicting temperatures near or below freezing. This is true especially during the winter months.

Be sure to take appropriate measures to protect your succulents, such as covering them with frost cloth or bringing potted succulents indoors.

2. Frost Damage

Frost can be particularly damaging to succulents.

If your succulents are exposed to frost, you may notice frost burns on the leaves, causing them to appear discolored or damaged.

Shielding your plants during cold nights with frost cloth or relocating them to a sheltered spot can prevent frost damage.

3. Extreme Temperature Fluctuations

Succulents generally prefer a stable climate.

Extreme temperatures fluctuations, especially when transitioning from warm days to cold nights, can stress the plants.

Monitoring and minimizing sudden temperature changes help maintain optimal conditions for your succulents.

4. Cold Winds

Cold winds, especially during the winter season, can strip these plants of moisture and contribute to desiccation.

If possible, create windbreaks or provide some form of shelter to shield them from harsh, cold winds.

5. Snow Accumulation

While some cold-hardy succulents can tolerate a light dusting of snow, heavy snowfall can weigh down the plants, potentially causing damage.

If your region experiences heavy snowy climates, gently brush off excess snow from your succulents to prevent them from becoming burdened and deformed.

6. Lack of Sunlight in Winter

In colder months, succulents may receive less sunlight due to shorter days and overcast skies.

Ensure that your succulents are placed in locations where they can still receive an adequate amount of sunlight.

Do this by either by positioning them strategically outdoors or supplementing with an artificial grow light for indoor plants.

If possible, always keep your tender succulents by a sunny window during cold winters.

7. Overwatering in Cold Months

Cold temperatures can slow down the growth and water requirements of succulents. Overwatering during colder months can lead to issues such as root rot.

Adjust your watering frequency based on the plant’s dormancy and environmental conditions.

8. Inadequate Drainage

Proper drainage is crucial for succulents, especially in cold weather. Excess water in the soil can lead to root rot, particularly when temperatures drop.

Ensure that your succulents are planted in well-draining soil and containers with drainage holes.

By keeping a close eye on these cold elements and taking proactive measures to protect your succulents, you can help them thrive even in challenging weather conditions.

Understanding the specific needs of your succulent species and adapting care practices accordingly will contribute to the long-term health and vibrancy of your plants.

Protective Measures: Shielding Your Succulents

Regardless of the succulent type, taking protective measures during cold spells is advisable.

Frost cloth or blankets can be employed to cover outdoor succulents on particularly cold nights.

Potted succulents benefit from relocation to sheltered areas or indoors during extreme cold snaps, providing an extra layer of defense against the chill.

Signs of Stress: A Watchful Eye

Observing your succulents for signs of stress during cold weather is essential.

Changes in color, such as a loss of vibrancy or darkening of leaves, indicate potential distress.

Promptly implementing protective measures can prevent further damage and ensure the overall health of your succulents.

How Cold is Too Cold For Succulents
