How do I know when to repot my houseplant?
Signs it's time to repot
The most obvious sign is roots escaping the drainage holes or circling the top of the soil. You might also see the plant wilting soon after watering because the root ball can't hold enough moisture. If the plant has stopped growing despite good light and fertilizer, it may be root-bound.
Another clue is when water runs straight through the pot. That means the soil has broken down and lost its water-holding capacity, or the roots have taken over. A healthy plant that suddenly needs water every couple of days is often telling you it's ready for a bigger home.
- Roots visible at drainage holes or surface
- Water runs through immediately
- Plant dries out faster than usual
- Growth has stalled despite care
- Pot feels top-heavy or roots crack the pot
When to hold off
Not every plant needs repotting on a schedule. Some, like snake plants and pothos, do fine slightly root-bound and may only need repotting every 2–3 years. Repotting stresses a plant, so only do it when necessary.
The best time to repot is in spring or early summer, when the plant is actively growing and can recover quickly. Avoid repotting in winter when growth is slow, unless the plant is in distress. If you're unsure, slide the plant out of its pot and check the roots—if they're circling tightly, it's time.
Common mistakes
- Repotting on a strict calendar schedule instead of checking the roots.
- Choosing a pot that's too large: it holds excess soil that stays wet and can rot roots.
- Repotting a plant that's already stressed from pests or disease, which can make things worse.
