Can You Repot Houseplants in Winter?
If you’ve spotted roots poking out of the drainage holes in January, or your Monstera suddenly looks miserable in the middle of winter, you might be wondering whether you should repot it now or wait until spring.
The short answer is yes, you can repot houseplants in winter—but only if there’s a good reason.
While spring is usually the best time to repot indoor plants, I’ve learned that plants don’t own calendars. If a houseplant genuinely needs help, waiting another three months just because it’s winter can often make the problem worse.
Here’s when I’d happily repot in winter, when I’d wait, and how to give your plant the best chance of recovering.
Why spring is usually the best time to repot
Most houseplants naturally slow down during winter.
With fewer daylight hours and lower light levels, plants grow much more slowly than they do in spring and summer. Because they’re not producing lots of new roots or leaves, they also take longer to recover from any disturbance.
Repotting always causes a little stress—even if you do everything correctly.
That’s why, if your plant is perfectly healthy, I’d usually wait until spring when it can bounce back much faster.
But healthy plants and struggling plants aren’t the same thing.
When you shouldn’t wait until spring
There are several situations where I’d ignore the calendar completely.
1. Your plant is badly root bound
If roots are circling the inside of the pot, growing through the drainage holes or pushing the plant upwards, it’s probably time.
A root-bound plant struggles to absorb water properly and eventually runs out of room to grow.
If you’re unsure whether that’s what you’re looking at, I’ve put together a step-by-step guide explaining how to repot a root-bound plant without damaging healthy roots.
When moving it, resist the temptation to choose a huge new container. Going up just one pot size is almost always enough, and my guide on what size pot you should use when repotting explains exactly why bigger isn’t always better.
2. The soil stays wet for days
This is probably the number one reason I’d repot during winter.
Over time, potting compost breaks down into tiny particles that hold onto far more water than they should.
If you’ve watered your plant once and the soil still feels soggy a week later, the compost may have reached the end of its life.
I covered this in much more detail in Why Does Houseplant Soil Stay Wet Too Long?, but fresh compost often solves the problem surprisingly quickly.
Whenever I repot, I use a good-quality houseplant potting mix rather than the cheapest compost I can find because it drains better and stays open for much longer. If a plant prefers excellent drainage, I’ll also mix in perlite or orchid bark, both of which make a noticeable difference without making the soil dry out too quickly.
3. Your plant has root rot
This is one situation where waiting until spring simply isn’t worth the risk.
Root rot spreads.
The longer damaged roots stay in wet compost, the harder it becomes to save the plant.
If you suspect root rot, I’d remove the plant immediately, trim away any soft black roots and repot into fresh compost.
If you’re not sure what root rot actually looks like, my guide to root rot in houseplants covers the warning signs and whether your plant can realistically be saved.
4. You’ve just bought a new plant
Not every new houseplant needs repotting straight away.
Most nursery pots are perfectly adequate for a few months.
However, if you’ve bought a discounted plant sitting in soaking wet compost or roots are already bursting out of the container, I wouldn’t hesitate to repot—even in winter.
Otherwise, I’d simply let it settle into its new home and wait until spring.
When I’d leave it alone
Sometimes the best thing you can do is… absolutely nothing.
If your plant:
- looks healthy
- is producing new leaves
- was repotted recently
- isn’t root bound
- isn’t sitting in permanently wet soil
I’d simply leave it where it is until the growing season begins again.
Not every plant needs rescuing.
Sometimes they just need patience.
How to repot houseplants safely in winter
If you’ve decided your plant really does need repotting, there are a few ways to reduce the stress.
Don’t jump up too many pot sizes
It’s surprisingly common to buy a pot that’s far too large.
Unfortunately, oversized pots hold lots of unused compost, and unused compost stays wet for much longer during winter.
That extra moisture dramatically increases the risk of root rot.
If you’re choosing a new planter, I’d usually only increase the diameter by around 2–5 cm depending on the size of the plant.
A terracotta pot with drainage holes is often a good choice for plants that dislike sitting in damp compost because the material naturally helps excess moisture evaporate.
Refresh the compost
Fresh compost isn’t just about nutrients.
It’s also about structure.
Old compost becomes dense and compacted, making it harder for roots to breathe.
Whenever I repot, I gently loosen the old root ball before adding fresh compost around it.
If you’re unsure which compost works best, my guide to the best houseplant soil mixes for every type of indoor plant explains which mixes suit tropical plants, succulents, orchids and more.
Be careful with watering afterwards
One of the biggest myths is that every repotted plant needs a huge drink.
Sometimes that’s true.
Sometimes it isn’t.
It depends on the plant, the condition of the roots and how moist the compost already was.
If you’re never quite sure when it’s actually time to water, a simple soil moisture meter can be surprisingly helpful. I still check the soil with my finger first, but moisture meters are a useful backup—especially if you’re new to houseplants.
I also explain this in more detail in Should You Water a Plant After Repotting?
Give your plant as much light as possible
Winter already means shorter days.
After repotting, try to place your plant somewhere bright but out of direct cold draughts.
If your brightest windowsill still feels gloomy, a small LED grow light can make a real difference while the roots establish. They’re particularly useful in north-facing rooms where natural light is limited for much of the winter.
If you’re unsure whether your plant is actually getting enough light, you’ll probably find my guide on how to tell if your houseplant is getting enough light useful.
Which houseplants don’t like winter repotting?
Although emergency repotting is sometimes necessary, I’d avoid disturbing these unless there’s a genuine problem:
- Snake plants
- ZZ plants
- Jade plants
- Most cacti
- Most succulents
These plants naturally rest during winter and usually recover much faster if you wait until spring.
My rule of thumb
I’ve stopped worrying so much about the season and started paying more attention to the plant.
If I’m only repotting because I think I should, I’ll happily wait until spring.
But if the plant is sitting in soggy compost, suffering from root rot or completely root bound, I’d rather repot it in winter than watch it slowly decline for the next few months.
Plants don’t always read the gardening books.
Sometimes they simply need help when they need help.
Frequently Asked Questions
Can you repot houseplants in January?
Yes. If your plant is root bound, suffering from root rot or trapped in poor-quality compost, January is perfectly acceptable. Healthy plants can usually wait until spring.
Will repotting shock my plant?
Some plants experience mild transplant shock, but choosing the correct pot size, using fresh compost and avoiding overwatering all help minimise it.
Should I fertilise after repotting in winter?
Usually not. Fresh compost already contains nutrients, and most houseplants won’t begin actively growing again until spring.
Can I repot a Monstera in winter?
Yes, if it genuinely needs it. If your Monstera is healthy, though, I’d wait until spring. If you do decide to repot, my guide to repotting a Monstera without damaging it walks you through the process.
Conclusion
Spring may be the traditional time for repotting, but it’s not a hard rule.
A healthy houseplant can usually wait a few more months. A struggling one often can’t.
By looking at what your plant is actually telling you—not just what the calendar says—you’ll make much better decisions and give your houseplants the best chance of thriving all year round.
