Understanding Succulents

Succulents are a diverse group of plants that store water in their leaves, stems, and roots, allowing them to survive in arid and semi-arid environments. They come in various shapes and sizes, making them popular choices for both indoor and outdoor gardens.

How Do Succulents Survive?

Succulents have developed unique adaptations to cope with harsh conditions, and these adaptations are key to their survival. Some of the most important features of succulents include

Water Storage

Succulents store water in their fleshy leaves, stems, or roots, enabling them to withstand long periods of drought.

Reduced Leaf Surface 

Many succulents have small or modified leaves that reduce water loss through transpiration.

Drought-Resistant Roots

Their roots are adapted to quickly absorb and store water when it becomes available

Sun Tolerance

Succulents are often equipped with adaptations that help them tolerate intense sunlight, such as a waxy coating or a thicker outer layer.

Cold Tolerance in Succulents

Typical Cold Tolerance Ranges

To give you an idea of what to expect, here are some general cold tolerance ranges for succulents

Hardy Succulents

 These are the most cold-tolerant, able to survive temperatures as low as -20°F (-29°C) or even lower. Examples include some types of sedum, sempervivum, and some opuntia cacti.

Moderate Cold Tolerance 

Many common succulents can withstand temperatures in the range of 20°F to 32°F (-6°C to 0°C). This includes various echeverias and crassula.

Low Cold Tolerance

Some succulents, particularly those native to warmer climates, can only endure mild cold and may be damaged or killed at temperatures below freezing. Examples include aloes and agaves.

When is Cold Too Cold for Succulents

Knowing when cold is too cold for succulents is crucial for their well-being. Here are some guidelines to help you determine when your succulents might be in danger:

Frost and Freezing Temperatures

Succulents are generally not equipped to handle frost and freezing temperatures for extended periods. When the temperature drops below 32°F (0°C) and stays there, succulents can suffer damage or even die.

Cold-Watering Risks

Watering your succulents during cold weather can be risky. When the water in the soil freezes, it can damage the plant’s cells, causing them to rupture. To avoid this, it’s best to water your succulents sparingly or not at all during cold spells.

Signs of Cold Damage

It’s essential to recognize the signs of cold damage in succulents. Common symptoms include

Browning or Blackening

Leaves may turn brown or black when they freeze or experience extreme cold.

Leaf Drop

Cold-damaged succulents may shed their leaves.

Stem Softening

The stem or leaves can become soft or mushy if cold damage occurs.

Slow Growth

 Cold can slow down the growth of succulents, and they may not recover until warmer conditions return.

Protecting Your Succulents from the Cold

While succulents are naturally adapted to survive in arid conditions, they still need protection from extreme cold. Here are some steps you can take to safeguard your succulents during cold weather.

Plant Selection

Choose cold-hardy succulent species for outdoor planting in regions with cold winters. If you live in an area with harsh winter conditions, opt for cold-resistant succulents like sedum varieties, sempervivum, and opuntia cacti.

Potting and Container Gardening

If you have succulents in containers, consider moving them indoors or to a more sheltered location during cold spells. Potted succulents are more vulnerable to cold because the soil in containers can freeze more quickly than in the ground.

 Provide Adequate Drainage

Well-draining soil and pots with drainage holes are essential for preventing water from accumulating around the roots. Excess moisture can freeze and damage the roots.

Mulch and Cover

For succulents planted in the ground, mulch can provide protection against freezing temperatures. Covering your succulents with burlap or frost cloths during cold nights can also help retain some heat.

Limit Watering

Reduce or eliminate watering during the cold season. Watering during cold weather can increase the risk of soil freezing, which can be harmful to your succulents.

Plant Placement

Plant succulents in locations that receive as much sunlight as possible during the day. This can help raise the temperature around your plants and minimize the impact of cold nights.

Monitoring and Relocation

Regularly check the weather forecast and be prepared to move your potted succulents indoors or to a sheltered area when extremely cold weather is expected.

Overwintering Succulents

In regions with extremely cold winters, succulent enthusiasts often practice overwintering. Overwintering involves moving your succulents indoors or into a sheltered environment to protect them from the cold. Here’s how you can go about it.

Selecting Indoor Space

Choose a well-lit indoor location with sufficient sunlight, like a south-facing window. A sunroom or a greenhouse is ideal if you have one


Before moving your succulents indoors, inspect them for any signs of pests or diseases. Remove any damaged or dead leaves.

Gradual Transition

Succulents should be gradually acclimated to the lower light and temperature conditions indoors. This can be done by reducing the amount of direct sunlight they receive each day for about two weeks.

 Pest Prevention

Keep an eye out for pests, as indoor environments can be more susceptible to infestations. Regularly check your succulents for signs of pests and treat them promptly if necessary.

Watering Indoors

Indoor succulents typically require less water than outdoor ones, as they won’t dry out as quickly. Be sure to adjust your watering schedule accordingly.

Winter Dormancy

Succulents may enter a state of winter dormancy during the colder months, during which they may grow more slowly or even become somewhat dormant. This is normal, and you should avoid forcing growth during this period.

Return Outdoors

When the threat of cold weather has passed and spring arrives, gradually reintroduce your succulents to outdoor conditions. Begin with a few hours of direct sunlight daily and gradually increase the exposure.
