Spider plants cannot survive freezing cold weather because they are tropical perennials at heart.
If you have been asking yourself, can spider plants survive cold weather, the honest answer is usually no when frost or prolonged cold is involved.
These resilient houseplants can tolerate a surprising amount of neglect when it comes to water and light, but cold temperatures are one of the few things that will actually stop them in their tracks.
While spider plants can survive cold weather in very mild zones with plenty of protection, anything below 50°F (10°C) signals serious danger for these green beauties.
In this post, we will cover exactly how cold is too cold, what cold damage looks like on the leaves and roots, and how to help spider plants survive cold weather indoors and out.
Let’s get into the details so you can keep your spider plant safe.
Why Spider Plants Cannot Survive Cold Weather
Understanding why spider plants cannot survive cold weather starts with a look at where they come from.
Spider plants are native to the tropical grasslands and forests of South Africa.
This means they evolved in consistently warm environments with very mild winters.
Their biology simply does not have the built-in mechanisms to handle frost, snow, or prolonged cold snaps.
Cold weather causes the water inside their delicate leaf cells to expand, which ruptures the cell walls from the inside out.
This is why leaves turn mushy and black after even a light frost.
Even if the air temperature is just a little too cool for too long, the plant’s metabolism slows down drastically.
When their metabolism slows, they stop absorbing water and nutrients from the soil.
This makes them extremely vulnerable to root rot and pests like fungus gnats.
So, if you want to know can spider plants survive cold weather outdoors in your area, the answer depends on your climate zone.
They are only truly safe outdoors year-round in USDA zones 9 through 11.
Ideal Temperature Range for Spider Plants
The ideal temperature range for a healthy, thriving spider plant is between 65°F and 85°F.
They can handle a slight dip into the upper 50s at night, but this is the absolute lower limit for survival.
If you want spider plants to survive cold weather indoors, keep them away from drafty windows in winter.
A sudden drop in temperature is much more shocking to them than a gradual one.
Avoid placing them near doors that open frequently to the outside or leaky window frames that let in cold air.
Consistency is key for these tropical plants when the temperature drops.
Why Frost is the Real Danger for the Leaves
Frost is the number one killer of spider plants left outside too late in the fall season.
When frost settles on the long, slender leaves, it freezes the plant tissue almost immediately.
There is no recovery for tissue that has been frozen completely solid.
This is the main reason spider plants cannot survive cold weather that includes even a light freeze.
Even if the main crown of the plant survives, the damaged leaves will need to be trimmed away.
This leaves the plant stressed, weakened, and looking very bare for the rest of the winter.
Signs Your Spider Plant is Suffering from Cold Weather
Recognizing the signs of cold stress early can help you save your plant before it is too late.
The first sign of cold trouble is usually visible in the leaves.
They may start to look droopy, yellow, or even slightly translucent.
If the exposure continues, the edges of the leaves will turn brown and crispy.
In severe cases, the leaves become completely mushy and turn black.
This happens because the cold weather has destroyed the cell structure of the leaf.
Another sign that spider plants cannot survive cold weather well is if they stop producing plantlets.
Spider plants are famous for sending out long stems with baby spiders on them.
When they are stressed by the cold, this reproductive process halts entirely.
The roots are also at serious risk in cold weather.
Cold soil retains moisture for much longer, creating the perfect environment for root rot.
If the roots rot, the plant cannot drink water no matter how much you pour in.
This is why a cold spider plant often looks thirsty, but watering it actually makes the situation worse.
How to Help Spider Plants Survive Cold Weather
The good news is that with a little planning, you can absolutely help spider plants survive cold weather.
The most effective strategy is to bring them indoors before the first frost of autumn hits.
If you have them growing in pots, this transition is very easy to manage.
Spray the leaves with insecticidal soap before bringing them inside to avoid bringing outdoor pests into your home.
Once indoors, place them in a spot with plenty of bright, indirect sunlight.
A south or west-facing window is usually the perfect spot for winter survival.
Watering less is also crucial for winter survival.
In winter, the plant is resting and not growing much at all.
Overwatering in cold weather is a death sentence because the roots simply rot in the cold, damp soil.
Let the soil dry out almost completely between waterings.
Providing Extra Warmth and Humidity Indoors
Once your spider plant is inside, you can help spider plants survive cold weather by giving them a little extra warmth.
Keep them away from icy cold windowsills where temperatures can drop significantly at night.
If your home is very dry in winter, consider using a small humidifier or placing a pebble tray with water under the pot.
This creates a microclimate of humidity that offsets the drying effects of indoor heating.
Do not fertilize your spider plant during the winter dormancy period.
Fertilizing in winter forces the plant to try to grow when the low light and cold weather are not supportive of new growth.
Wait until spring when the temperatures rise and the plant naturally wakes up.
Can Spider Plants Survive Cold Weather in Storage?
Many people wonder if they can store their spider plants in a dark garage for the winter.
While spider plants can tolerate low light, they cannot tolerate extremely cold temperatures.
If your garage stays above 50°F, they might just survive the winter there.
However, they will likely go dormant and lose most of their vibrant green color.
A basement is usually a better option for dormancy if it has a small window and stays warm.
So, can spider plants survive cold weather in storage? Only if the storage space is heated.
So, Can Spider Plants Survive Cold Weather?
Spider plants cannot survive cold weather that involves frost or freezing temperatures at all.
They are tropical plants at heart that need consistent warmth to truly thrive and live.
While spider plants can survive cold weather in the short term if the temperature stays above 50°F, prolonged exposure will cause irreversible damage.
The best way to ensure your spider plant survives is to bring it indoors before winter arrives.
If you live in a warm climate like zone 9 or above, keep an eye on the weather forecast.
A single night of unexpected frost can end the life of a beautiful, mature spider plant very quickly.
I hope this guide helps you understand exactly how much cold your spider plant can actually handle.
With the right care and attention, spider plants can survive cold weather transitions smoothly and keep growing for years to come.
Please bring them inside at the very first sign of a cold snap this winter.
