Spider plants (Chlorophytum comosum) are one of the most popular indoor plants because of their easy care and air-purifying qualities. But like many houseplants, they have their limits especially when it comes to cold weather. If you’re wondering how much cold a spider plant can handle before it starts to suffer, this guide will explain everything you need to know.
What Is the Cold Tolerance of a Spider Plant?
Spider plants prefer warm, moderate temperatures, similar to their native tropical and subtropical environments. The lowest temperature a spider plant can tolerate is around 35°F (1.6°C), but they thrive best between 65°F to 80°F (18°C to 27°C).
If temperatures drop below 50°F (10°C), your spider plant may start showing signs of stress like:
- Wilting leaves
- Brown leaf tips
- Slowed growth
- Yellowing leaves
Freezing temperatures (32°F / 0°C or lower) can cause severe damage, including mushy leaves and root rot. In most cases, prolonged exposure to such cold can kill your plant.
Ideal Temperature Range for Spider Plants
For healthy growth:
- Daytime Temperature: 65°F to 80°F (18°C to 27°C)
- Nighttime Temperature: Not lower than 50°F (10°C)
Anything below 50°F puts your spider plant at risk. This is why it’s important to move outdoor spider plants inside when cold weather arrives or avoid placing indoor ones near drafty windows during winter.
Can Spider Plants Survive Frost?
No, spider plants are not frost-tolerant. Even a brief exposure to frost can damage the plant’s tissues, causing the leaves to turn black, wilt, or become mushy. If your area experiences frost, it’s essential to either:
- Bring your plant indoors
- Cover it with a frost cloth if temporarily outdoors
- Keep it in a warm, protected area like a sunroom or insulated porch
How to Protect Spider Plants in Cold Weather
If you live in a region with chilly winters, follow these simple tips to keep your spider plant safe:
- Keep away from windows and doors that may let in cold drafts.
- Avoid placing near air conditioners, heaters, or radiators which can cause sudden temperature changes.
- Move outdoor plants inside once nighttime temperatures drop below 50°F (10°C).
- Use room heaters carefully to maintain a consistent temperature if your indoor space gets too cold.
- Water less frequently in winter since spider plants go semi-dormant and overwatering in cold soil can lead to root rot.
Signs Your Spider Plant Is Too Cold
If your spider plant gets too cold, it’ll show these warning signs:
- Droopy, limp leaves
- Brown, crispy edges
- Black or mushy leaf tips
- Yellowing or discolored foliage
- Stunted or no new growth
If you notice any of these, move your plant to a warmer location immediately.
Can Spider Plants Be Kept Outside in Winter?
It depends on your climate.
- In USDA hardiness zones 9-11 (where temperatures rarely drop below 50°F), spider plants can stay outside year-round.
- In colder zones, it’s best to bring them indoors for the winter months.
Quick Temperature Tolerance Summary for Spider Plants:
| Condition | Temperature | Effect on Spider Plant |
| Ideal Growing Range | 65°F to 80°F (18°C to 27°C) | Healthy growth, lush foliage |
| Minimum Safe Temperature | 50°F (10°C) | Plant stress may begin |
| Danger Zone | Below 35°F (1.6°C) | Tissue damage, possible death |
| Frost & Freezing | 32°F (0°C) and below | Severe damage or death |
Final Thoughts
To keep your spider plant happy and thriving, it’s important to maintain temperatures above 50°F (10°C) and avoid exposing it to frost or freezing drafts. By bringing your plant indoors during cold months and providing a cozy, draft-free environment, you’ll enjoy those beautiful arching green-and-white leaves all year long.
Remember: Spider plants are tough, but cold is one thing they can’t tolerate for long.
Frequently Asked Questions (FAQs):
Can spider plants survive outside in winter?
Only in warm climates (USDA zones 9-11). In colder regions, they should be moved indoors when temperatures drop below 50°F (10°C).
What temperature kills a spider plant?
Prolonged exposure to 32°F (0°C) or lower can kill a spider plant.
Do spider plants like cold rooms?
No, spider plants prefer moderate, warm temperatures and dislike cold drafts or chilly rooms below 50°F (10°C).
