Can succulents survive the winter, indoors and out

Quick Answer

Deciding whether to move your plants indoors prevents the cost of replacing dead tissue from frost damage. In this guide, Green Writer walks through how succulents survive the winter by identifying the specific light and temperature needs for each variety.

Succulents often require more light than they receive indoors during cold months, so you can grow various succulent types with a grow light when windows become less effective.

Winter survival for different succulents

Succulents can survive the winter if you maintain a draft-free location that does not dip below about 50 degrees. Most species enter a period of reduced activity during cold months. You must adjust your care based on whether your specific plant species requires a cold rest or remains active.

Watering requirements for dormant succulents

Dormant succulents are types of plants that stop growing and slow their metabolic processes during the winter. These plants require a reduction in water to prevent rot while they are inactive. You can identify these by checking if the species requires a cool period to trigger new growth in the spring.

Dormant succulents require less water during the winter

Dormant succulents are plants that enter a period of rest during the colder months. During this time, the plant slows down its growth and metabolic processes. Knowing this helps you decide to reduce watering frequency to prevent root rot.

Succulents that do not enter dormancy stay active and require consistent care. These plants need a steady supply of light and regular water to maintain their health throughout the winter months.

Do succulents survive the cold months?

Succulents survive the winter by staying in temperatures above 50 degrees. You can keep them indoors near a south-facing window to provide the necessary light. If you keep them outside, you can grow sedums succulents of various types to ensure the local temperature stays above the minimum threshold for your specific variety.

Can I leave my succulents outside during the winter?

You can leave your succulents outside during the winter if the species is rated as cold hardy. These specific plants survive freezing temperatures while others suffer cellular damage. Check the specific species requirements before moving any plants outdoors for the season.

Cold hardy Sempervivum and Sedum species

Cold hardy succulents include the Sempervivum genus, which forms tight rosettes and survives in rocky crevices. These plants endure extreme frost. The Sedum species, such as Sedum album, possess thick leaves that resist freezing temperatures. These varieties survive in many climates without indoor protection.

Cold hardy succulents can survive outdoor winter temperatures

Cold hardy succulents are specific species that can withstand freezing temperatures without dying. These plants are identified by their ability to endure frost and low temperatures. You must identify your species to decide if it can stay outside or needs moving.

Succulents require a draft-free location that does not dip below about 50 degrees if they remain indoors. You can choose different types of succulents before moving non-hardy plants inside before the first frost occurs to prevent tissue death.

Keeping cactus plants in outdoor winter weather

Cactus plants generally require protection from freezing temperatures. Most species die if they stay outside in snow or ice. Move these plants to a garage or unheated shed to stay above freezing.

Damage from freezing temperatures on outdoor plants

Succulents will suffer cellular damage or die if they stay outside in freezing temperatures. Cold weather causes the water inside the plant cells to freeze and expand. This process ruptures cell walls and destroys the internal structure of the plant tissue.

Effects of hard freezes on leaves

Most succulents require a draft-free location that does not dip below about 50 degrees. If a plant experiences a hard freeze, the leaves may turn mushy or black. This damage occurs because the internal moisture expands as it turns to ice, so you should replant succulents that have outgrown their pot.

Using a greenhouse for frost protection

A greenhouse provides a controlled environment to protect plants from frost. A greenhouse is a structure with walls and a roof designed to provide a controlled environment for growing plants. Moving succulents into a greenhouse changes their exposure to external temperatures. This structure keeps the air warm enough to prevent cell rupture during winter months.

Signs that a succulent is struggling with cold

Succulents show stress through shriveled leaves or darkened spots on the foliage. You may notice the plant lose its firm texture as the internal structure breaks down. These changes indicate the plant is no longer able to maintain its cell integrity.

How do I move my succulents indoors for the winter?

You move my succulents indoors for the winter by relocating pots to a draft-free area with consistent light. Succulents require a location that does not dip below about 50 degrees. This transition protects plants from freezing temperatures and frost damage.

Indoor transition steps for echeveria

1. Select a south-facing window to provide at least 6 hours of sunlight daily. Sunlight is the natural light and heat from the sun that plants use to grow.
2. Check the soil moisture to ensure the plant is dry before moving it.
3. Place the pot on a stable surface away from cold drafts or heaters.
4. Monitor the leaves for color changes to verify the plant is acclimating to the indoor light.

Transitioning cacti and echeveria to indoor spaces

Succulents adjust to indoor environments by changing their growth rate based on available light. A south-facing window provides the strongest sunlight for these species. You can use grow lights when windows fail by observing the stem firmness.

Light requirements for indoor succulents in winter

Succulents need a moderate amount of light during the winter months. According to UNH Extension, Succulents Shine in Winter, succulents are not demanding if you can provide a moderate amount of light. The source specifies a preference for 6 hours from a south-facing window. However, the source notes that an east or west window will usually suffice.

Draft free locations for indoor plants

Placement matters for maintaining plant health. Set your succulents in a draft-free location. The temperature in this area should not dip below about 50 degrees. These conditions help the plant maintain its structure while you choose succulents for beginners during the shorter days.

How much sunlight do indoor succulents need during the winter months?

Indoor succulents require a moderate amount of light to survive the winter. A south-facing window provides the most consistent light, while you can keep succulents compact with proper conditions. East or west-facing windows work as secondary options for light exposure.

Prepare your succulents for the winter months

Deciding how to house your plants depends on your current indoor temperature and the available light in your home.

Winter care checklist

1. Identify your current indoor temperature. Check your thermostat or a thermometer. The location must not dip below about 50 degrees.
2. Assess the available light in your home. Look for a south-facing window for 6 hours of light. If unavailable, check if east or west windows provide sufficient brightness.
3. Verify your pot drainage system. Ensure your container has holes. Water must flow out of the container holes to prevent rot.
4. Adjust your watering schedule. Water less during winter. Let the soil dry between waterings to keep the plants healthy.
5. Consult the University of Maryland Extension, Selecting Indoor Plants. Read this guide to confirm your specific succulent's needs. If the instructions differ from your current setup, adjust your care routine.
