How to Repot a Houseplant Step by Step
Every houseplant eventually outgrows its pot, and repotting gives the roots fresh soil and room to grow. Done gently and at the right time, it gives a plant a burst of new life rather than a shock.
- Repot when roots circle the pot or poke out of the drainage holes.
- Choose a pot only one or two inches larger than the current one.
- Loosen the roots gently before settling the plant into fresh soil.
- Water lightly after repotting and keep the plant out of direct sun for a few days.
Know when to repot
Most houseplants need repotting every one to two years. Signs it's time include roots growing out of the drainage holes, a plant that dries out immediately after watering, or roots circling the inside of the pot when you gently lift the plant out. Spring, when growth resumes, is the best time, but a truly root-bound plant can be repotted any time it needs it.
Choose the right pot and soil
Select a new pot just one to two inches wider than the current one — a pot that's too large holds excess water and can rot the roots. Make sure it has drainage holes, and use a fresh indoor potting mix suited to your plant. A little fresh soil goes a long way, because it replaces nutrients the old mix has lost.
Step 1: Remove the plant gently
Water the plant lightly the day before so the root ball holds together. Turn the pot on its side, tap the sides and bottom, and ease the plant out by the base of the stem rather than tugging on the leaves. If the plant is stuck, run a knife around the inside edge of the pot to loosen it.
Step 2: Loosen the roots
Gently tease apart the outer roots with your fingers, especially any that are circling the root ball. Loosening them encourages the roots to grow outward into the new soil instead of continuing to wrap around themselves. For a badly root-bound plant, you can make a few shallow vertical cuts in the root ball with a clean knife.
Step 3: Repot and water
Add a layer of fresh soil to the bottom of the new pot, set the plant in so it sits at the same depth as before, and fill around the sides with more soil, pressing gently to remove air pockets. Leave a little space at the top so water doesn't spill over. Water lightly to settle the soil, and keep the plant in bright, indirect light for a few days while it adjusts.
Choose the right pot size
It's tempting to give a plant a much larger pot so you don't have to repot again soon, but that usually backfires. A pot that's too big holds far more soil than the roots can use, and that excess soil stays wet, leading to root rot. A new pot just one to two inches wider than the current one is almost always the right choice.
When in doubt, go smaller. A plant that fills its pot with healthy roots is a happy plant, and a gradual move up in size keeps the root system balanced with the soil around it.
Top-dress when you can't repot
Sometimes a plant is too large to repot, or you want to wait until spring. In those cases, top-dressing helps: scrape away the top inch or two of old soil and replace it with fresh potting mix. This refreshes nutrients and improves the surface soil without disturbing the roots.
Top-dressing isn't a permanent substitute for repotting, but it's a useful way to give a large, established plant a gentle boost in place.
Frequently asked questions
Do I need to repot a new plant right away?
Not usually. Most new plants are fine in their nursery pot for a while. Give it a few weeks to adjust to your home, then repot only if it's root-bound or you want a different pot.
Why is my plant drooping after repotting?
Mild transplant shock is normal and usually passes within a few days. Keep the plant out of direct sun, water lightly, and give it time — most plants perk back up on their own.
Can I reuse old potting soil?
It's best to use fresh soil, because old soil loses structure and nutrients. You can mix a little old soil into the new if it's clean and disease-free, but fresh mix gives better results.
