Spider plants cannot tolerate cold temperatures well and are not frost-hardy plants.
If you’ve been wondering whether spider plants tolerate cold conditions, the short answer is no.
While spider plants can handle cooler indoor temperatures, they struggle when exposed to prolonged cold or freezing weather.
Spider plants are tropical by nature, so cold drafts and frost can damage their leaves and roots.
In this post, we’ll explore whether spider plants tolerate cold, what temperature range they need, and how to protect them during winter.
Let’s dive into keeping your spider plant healthy when temperatures drop.
Why Spider Plants Tolerate Cold Only to a Limit
Spider plants tolerate cold only within a specific temperature range.
They come from tropical regions where warmth and humidity are the norm.
Here’s what you need to know about their cold tolerance limits.
1. The Ideal Temperature for Spider Plants
Spider plants thrive in temperatures between 65°F and 75°F (18°C to 24°C).
When temperatures drop below 50°F (10°C), spider plants begin to show signs of stress.
They can survive briefly in the 50s, but prolonged exposure will cause damage.
If you live in a climate where nights get cold, bring your spider plant indoors.
Spider plants tolerate cold poorly once the mercury hits 40°F or lower.
2. Signs That Spider Plants Tolerate Cold Poorly
When spider plants tolerate cold less than they should, you’ll notice visual clues.
Leaves may turn yellow, brown, or black at the tips.
The foliage can become limp or mushy if frost has touched the plant.
Growth slows down dramatically, and the plant may stop producing new shoots.
If you see these signs, your spider plant is telling you it’s too cold.
Spider plants tolerate cold stress only for a short time before permanent damage occurs.
3. Why Spider Plants Don’t Handle Freezing
Spider plants are not built for freezing temperatures.
Their cells contain a lot of water, and when that water freezes, ice crystals form.
Those ice crystals rupture the cell walls, leading to leaf rot and root death.
Unlike hardy outdoor perennials, spider plants have no natural frost protection.
So no, spider plants tolerate cold freezing conditions not at all.
Even a single night of frost can kill an outdoor spider plant.
How to Care for Spider Plants in Winter
Since spider plants tolerate cold only indoors during winter, moving them inside is essential.
Here’s how to keep your spider plant happy when temperatures drop.
1. Move Spider Plants Indoors Before Frost
Bring your spider plant inside as soon as nighttime temperatures fall below 50°F.
Place it in a bright room with indirect sunlight, like near an east-facing window.
Avoid placing it right next to drafty windows or doors.
Cold drafts can shock the plant, even if the room is warm.
Spider plants tolerate cold much better when they are in a stable indoor environment.
2. Reduce Watering During Cold Months
Spider plants grow slower in winter, so they need less water.
Overwatering in cold conditions can lead to root rot.
Only water when the top inch of soil feels dry.
Drain excess water from the saucer to prevent soggy roots.
Remember: spider plants tolerate cold better when their soil is on the drier side.
3. Increase Humidity Around the Plant
Indoor heating can dry out the air, which stresses spider plants.
 
Spider plants tolerate cold dry air less effectively than warm humid air.
 
Mist the leaves occasionally or use a pebble tray with water.
 
Grouping plants together also helps maintain humidity.
 
This keeps the foliage lush and green during winter.
 
Can Spider Plants Survive Outdoors in Cold Climates?
Spider plants survive outdoors only in USDA hardiness zones 9 to 11.
 
In colder zones, you cannot leave them outside year‑round.
 
If you keep spider plants in pots, you can move them inside and out as seasons change.
 
Gardeners in cooler areas often treat spider plants as annuals or houseplants.
 
Spider plants tolerate cold outdoor conditions only during the warm months.
 
Once autumn arrives, it’s time to bring them back inside.
 
1. Mulching Is Not Enough for Spider Plants
Some plants survive winter with heavy mulching, but not spider plants.
 
Mulch insulates the soil, but spider plants’ shallow roots still freeze.
 
Even if the top growth dies, the roots rarely recover.
 
Spider plants tolerate cold mulching techniques very poorly.
 
The safest approach is to bring them indoors before the first frost.
 
2. Overwintering Indoors as a Houseplant
Many people simply keep spider plants as houseplants year‑round.
 
They adapt well to indoor life and are very low maintenance.
 
During winter, they might not grow much, but they will survive.
 
In spring, you can move them back outside after the last frost.
 
Spider plants tolerate cold indoor conditions just fine as long as the room stays above 50°F.
 
So, Can Spider Plants Tolerate Cold?
Spider plants cannot tolerate cold temperatures below 50°F.
 
They are tropical plants that need warmth, humidity, and protection from frost.
 
If you keep them indoors during winter and avoid cold drafts, they will thrive year‑round.
 
For outdoor plants, bring them inside before the first frost.
 
Spider plants tolerate cold only when you take simple precautions.
 
Now you know exactly how to keep your spider plant safe and happy through the chilly months.
