Spider plants cannot survive frost.
Frost is simply too harsh for these tropical houseplants.
If you’ve been asking whether spider plants survive frost, the short answer is no.
These tender perennials originate from warm climates and can’t handle freezing temperatures.
Exposure to frost causes leaves to turn mushy and black, eventually killing the plant.
In this post, we’ll explore why spider plants can’t survive frost, what happens when they’re exposed, and how to protect them from cold damage.
Let’s dig in.
Why Spider Plants Cannot Survive Frost
Spider plants are native to tropical and subtropical regions of Africa.
They evolved in warm, humid environments where temperatures rarely dip below 50°F (10°C).
Frost occurs when temperatures fall below 32°F (0°C), and that’s a death sentence for spider plants.
Here are the main reasons spider plants cannot survive frost:
1. Cellular Damage from Ice Crystals
When frost hits, water inside the plant’s cells freezes.
Ice crystals form and puncture the cell walls, causing irreversible damage.
This is why you’ll see mushy, water-soaked spots on the leaves after a frost event.
Once the cells burst, the plant can’t recover, and the tissue dies.
That’s the core reason spider plants cannot survive frost.
2. Lack of Cold Hardiness
Some plants have evolved mechanisms to survive frost, like producing antifreeze proteins or going dormant.
Spider plants have none of those adaptations.
They are classified as cold-sensitive perennials, meaning they thrive in USDA zones 9–11.
If you live outside those zones and leave spider plants outdoors during winter, frost will kill them.
Even a light frost with temperatures around 30°F (–1°C) can cause severe damage.
3. Roots Are Not Frost-Tolerant
Even if you try to protect the leaves, the roots of spider plants are equally vulnerable.
Spider plants have fleshy, tuberous roots that store water, but those roots freeze easily.
When the soil freezes, the roots can’t absorb water or nutrients.
Frozen roots rot quickly after thawing, leading to plant death.
So even if the top of the plant looks okay after a light frost, the roots may already be compromised.
That’s another reason spider plants cannot survive frost in the ground.
What Happens When Spider Plants Are Exposed to Frost
If you accidentally leave your spider plant out during a frost, you’ll notice symptoms within hours.
Here’s what typically occurs:
1. Leaves Turn Black or Brown
The first sign of frost damage is discoloration.
Leaves may turn dark green, then black, especially at the tips and edges.
This happens because the frozen cells die and their contents leak out.
The blackened leaves will never turn green again.
2. Leaves Become Mushy
Frost-damaged tissue often becomes soft and slimy.
If you touch the leaf, it may feel like wet paper.
This mushy texture is a clear sign that the cells have burst.
Once mushiness sets in, the leaf is dead and should be removed.
3. Plant Collapses
In severe frost exposure, the entire plant may wilt and collapse.
The stems become limp, and the leaves droop beyond recovery.
At this point, spider plants cannot survive frost damage, and the plant is likely a goner.
How to Protect Spider Plants from Frost
Prevention is the best strategy because spider plants cannot survive frost once it hits.
Here are practical ways to keep your spider plant safe:
1. Bring Them Indoors Before Frost
The simplest protection is to move your spider plant indoors before the first frost forecast.
Check your local frost dates and bring the pot inside when nighttime temperatures drop below 50°F (10°C).
Indoor spider plants thrive in bright, indirect light and temperatures between 60–80°F (15–27°C).
That way, you never have to worry whether spider plants survive frost because they never experience it.
2. Use Frost Covers for Outdoor Potted Plants
If you can’t bring the plant inside, cover it with a frost blanket, burlap, or even a cardboard box overnight.
The cover traps heat radiating from the soil and prevents frost from settling directly on the leaves.
Make sure the cover reaches the ground to seal in warmth.
Remove the cover during the day to let the plant breathe.
This method can help borderline temperatures, but it’s not foolproof.
3. Mulch Around the Base
For spider plants planted in the ground, a thick layer of mulch around the base can insulate the roots.
Use straw, shredded bark, or leaves to a depth of 3–4 inches.
Mulch slows down soil freezing and can buy you a few degrees of protection.
However, remember that severe frost will still kill the foliage even if roots survive.
So this is a last resort for mild climates only.
4. Choose Protected Planting Locations
If you must grow spider plants outdoors in a borderline zone, plant them against a south-facing wall or under an overhang.
These spots absorb heat during the day and release it at night, reducing frost risk.
Avoid low-lying areas where cold air collects.
Even with these tricks, spider plants cannot survive frost if temperatures drop too low for too long.
So, Can Spider Plants Survive Frost?
Spider plants cannot survive frost.
Frost causes ice crystals to form inside the cells, leading to irreversible damage and death.
These tropical plants lack any natural cold-hardiness mechanisms.
The best way to ensure your spider plants survive frost is to never let them experience it.
Bring them indoors before the first frost, or provide protective covers if you live in a mild climate.
Now you know the answer to whether spider plants survive frost, and you have actionable tips to keep your plant safe.
Happy growing.
