Spider Plants are fast-growing, easy-going houseplants—but even they eventually outgrow their pots. Learn when to repot, how to choose the right pot and soil, and how to help your Spider Plant thrive after the move.
Spider Plants (Chlorophytum comosum) are some of the easiest houseplants to grow, but they don’t like being cramped forever.
As they mature, their thick, fleshy roots quickly fill the pot, leaving little room for fresh soil or water. Eventually, your once-happy plant may stop growing, dry out more quickly or start pushing itself out of its container.
Fortunately, repotting a Spider Plant is simple—and if you do it correctly, your plant will reward you with plenty of fresh growth and even more baby Spider Plants.
Here’s everything you need to know.
When should you repot a Spider Plant?
Most Spider Plants benefit from repotting every 1–2 years.
Younger plants tend to grow faster and may need a new pot every year, while mature plants can often stay put a little longer.
Look out for these signs:
- Roots growing through the drainage holes
- Thick roots visible on the soil surface
- Water running straight through the pot
- Soil drying out within a day or two
- Slower growth during spring and summer
- The plant becoming top-heavy

Signs Your Houseplant Needs Repotting (And What to Do About It)
The best time to repot
Spring and early summer are ideal.
At this time of year, your Spider Plant is actively growing and will recover quickly from the move.
Repotting in winter is possible if the plant is severely root-bound, but if there’s no urgency, waiting until spring usually produces the best results.

Choose the right pot
One of the most common mistakes is choosing a pot that’s far too large.
Instead, select one that’s approximately 2–5cm (1–2 inches) wider than the current pot.
This provides enough room for new roots without leaving large amounts of wet compost sitting around them.
Always choose a pot with drainage holes.
The best soil for Spider Plants
Spider Plants prefer a light, free-draining compost that holds moisture without becoming waterlogged.
A simple mix works well:
- High-quality houseplant compost
- Perlite
- A small amount of orchid bark (optional)
This helps keep the roots healthy while preventing soggy conditions.

Water before repotting
Give your Spider Plant a thorough watering the day before you repot.
Slightly moist compost slides out much more easily than dry soil and reduces stress on the roots.
Avoid repotting immediately after heavy watering when the compost is soaking wet.
Remove the plant carefully
Lay the pot on its side and gently support the base of the plant.
Slide the root ball out slowly.
If it’s stuck:
- Gently squeeze plastic pots.
- Tap around the outside.
- Run a blunt knife around the inside edge.
Avoid pulling on the leaves.
Spider Plant foliage bends easily and can snap if handled roughly.
Should you loosen the roots?
Usually, only a little.
Spider Plants naturally develop thick, fleshy roots that store water.
If the roots are tightly circling the outside of the root ball, gently tease a few loose with your fingers.
Don’t completely pull the root ball apart unless you’re dividing the plant.
Can you divide a Spider Plant while repotting?
Yes—and repotting is actually the perfect opportunity.
If your Spider Plant has formed several separate clumps, you can carefully divide them into individual plants.
Each section should have:
- Healthy roots
- A growing crown
- Several leaves
If you’re looking to grow even more plants, don’t forget you can also propagate the babies.

How to Propagate a Spider Plant
Plant into fresh compost
Add a layer of fresh compost to the bottom of the new pot.
Position the Spider Plant so it sits at the same height as before.
Fill around the sides with fresh compost and gently firm it into place.
Avoid packing the soil too tightly.
Roots need air as well as water.
Water after repotting
Once planted, water thoroughly until water drains from the bottom.
Allow the excess to drain away completely.
Avoid leaving the pot standing in water.
If you’d like more guidance, see:
Should You Water a Plant After Repotting?
What happens after repotting?
Your Spider Plant may look a little unhappy for a few days.
That’s perfectly normal.
Keep it:
- In bright, indirect light
- Away from strong afternoon sun
- Evenly moist (but not soggy)
- Out of cold draughts
Most plants settle within a couple of weeks and soon begin producing fresh growth.
Common repotting mistakes
Choosing a pot that’s too large
Large pots stay wet longer, increasing the risk of root rot.
Using heavy compost
Spider Plants prefer light, airy soil.
Damaging the roots
Be gentle when removing the plant and teasing out the roots.
Overwatering afterwards
Fresh compost already holds plenty of moisture.
Always check the soil before watering again.
Repotting too often
Spider Plants actually enjoy being slightly snug in their pots.
Don’t repot simply because it’s been a year.
Repot when the plant shows genuine signs that it needs more space.
Frequently Asked Questions
Do Spider Plants like to be root bound?
Yes—to a point.
Spider Plants tolerate being slightly root-bound better than many houseplants, but eventually they’ll run out of space and need a larger pot.
Should I remove all the old soil?
No.
Remove only loose compost while leaving most of the root ball intact.

Should You Remove Old Soil When Repotting Houseplants?
Can I repot a Spider Plant in winter?
Only if absolutely necessary.
Otherwise, wait until spring.
Should I fertilise after repotting?
Wait around four weeks before feeding.
Fresh compost usually contains enough nutrients to get your plant started.
Final Thoughts
Spider Plants are wonderfully forgiving houseplants, and repotting them is one of the easiest ways to keep them healthy and productive.
By choosing a slightly larger pot, using a free-draining soil mix and avoiding unnecessary root disturbance, you’ll encourage strong new growth—and before long, you’ll probably have even more Spider Plant babies to propagate.
