Today, I’m answering a viewer question from Suzette, who asked if I have recommendations for pruning a plant in relation to repotting. Should you prune before or after repotting—or wait entirely? Let’s get into it.
This is a Tenan (Calathea), which I plan to repot soon, so I’ll use it to help answer Suzette’s question. By the way, I have another video specifically on pruning that I’ll link below, along with any other videos I reference here.
Do You Always Need to Prune When Repotting?
No—you don’t always have to prune when repotting. But there are several reasons why you might want to. Let’s go over those reasons:
1. Dead or Dying Foliage
One of the main reasons to prune when repotting is if there’s visible dieback. If you notice dying or dead leaves, prune them out. This helps the plant focus its energy on root acclimation rather than wasting it on failing foliage.
2. Top-Heavy or Rangy Plants
Some plants—like large-leaf philodendrons—can become top-heavy. If you repot them in that state, they may topple over, potentially breaking at the base and damaging the root system. Pruning back top growth helps balance the plant.
3. Controlling Size in the Same Pot
If your plant is outgrowing its pot but you don’t want to size up, you can prune both the top growth and the roots. This keeps the plant more compact while allowing you to add fresh soil—what I call “resoiling.”
When doing this, only cut up to one-third of the roots and one-third of the top growth. Any more could shock the plant.
Proportional Pruning
Always prune proportionally—if you cut from the top, do a proportional cut from the root system. This keeps the plant balanced and reduces stress.
Be Cautious
Only prune if it’s really necessary. Many houseplants don’t need much pruning, and too much can put them into shock. Be mindful of timing and the amount you remove.
I also have an entire playlist on pruning—this video is part of it—and I’ll link that as well.

FAQs About Pruning When Repotting Houseplants
Should you prune a plant before or after repotting?
It depends on the plant’s condition. If there’s dead or dying foliage, or the plant is top-heavy or rangy, pruning before repotting can help reduce stress.
Is pruning always necessary when repotting?
No, pruning is not always necessary. Only prune if there are clear signs like dead foliage, size control needs, or balance issues with top-heavy plants.
Can pruning too much harm the plant?
Yes, pruning more than one-third of the top or roots can shock the plant and potentially kill it. Always prune conservatively and proportionally.
Why prune roots and top growth at the same time?
When keeping a plant in the same pot, root pruning must match top pruning to maintain balance and avoid plant stress during repotting.
What is “resoiling” in plant care?
Resoiling refers to keeping the plant in the same pot but replacing the old soil with fresh potting mix. Minor root and top pruning may be needed during this process.
