How do I know when to repot a houseplant?

Look for roots circling the surface or growing out the drainage holes, water that runs straight through, or a plant that dries out and droops within a day or two. Most houseplants need repotting every 1–2 years as they outgrow their pot.

What's the best time of year to repot?

Early spring, as the plant enters active growth, so it recovers quickly. Avoid repotting a dormant plant in the depths of winter unless it's an emergency like root rot.

How much bigger should the new pot be?

Only one size up — about 2–5 cm (1–2 inches) wider. A pot that's too large holds excess wet soil around the roots, which invites rot rather than faster growth.

When and how to repot a houseplant

Published 28 July 2026

Repotting is one of the few care jobs where doing it more isn’t better. A plant doesn’t want a bigger home every spring — it wants the right-sized one, changed only when it’s genuinely outgrown the old one. Repot on a hunch and you set it back; wait too long and the roots wind into a tight ball that can’t drink.

The trick is knowing the actual signals, and then changing as little as possible.

Signs it’s actually time

Roots escaping the drainage holes, or circling the surface of the soil.
Water runs straight through and out the bottom without wetting the soil — the pot is more root than soil.
The plant is top-heavy and tips over, or dries out far faster than it used to.
It’s been two-plus years in the same pot and growth has stalled despite good light and watering.

One or two of these together is your cue. A plant that’s simply thirsty or yellowing usually doesn’t need a repot — it needs a different fix.

When not to repot

Skip it if the plant is sick, stressed, or in the middle of winter dormancy. Repotting is minor surgery; do it when the plant is growing and strong, ideally in spring or early summer. A struggling plant needs its problem solved first, not a new pot.

Choosing the next pot

Go one size up — about 2–4 cm wider. Too big is a real mistake: a small plant in a huge pot sits in a mass of wet soil its roots can’t drink, and rot follows. Make sure the pot has a drainage hole. Terracotta breathes and dries fast (forgiving if you tend to overwater); glazed and plastic hold moisture longer.

The steps

Water the plant a day before — moist roots handle the move better.
Ease it out; gently tease apart circling roots and trim any brown, mushy ones.
Add fresh, airy mix to the new pot, set the plant at the same depth as before, and fill around it.
Water thoroughly to settle the soil, then let it drain.

After repotting

Fresh soil holds more water than the old root-bound mass, so ease off watering for a couple of weeks and let the plant settle before feeding. Its whole watering rhythm just changed — a bigger pot and new soil dry out on a different schedule than the old one did.

That shift is easy to forget, and it’s exactly the kind of change Foliora tracks for you: when you repot, it adjusts the plant’s care to the new pot and soil, instead of holding it to a rhythm that no longer fits.
