When and How to Repot Houseplants

Repotting refreshes tired soil and gives roots room to grow, but doing it too often or into a pot that is far too large causes more harm than good. 100% Local

Signs a plant needs repotting

Roots growing out of the drainage holes or circling the surface.
Water running straight through the pot, or drying out unusually fast.
Growth stalling even with good light and regular feeding.
The plant looks top-heavy and topples easily.

Most houseplants need repotting every one to three years. Fast growers and young plants need it sooner; slow succulents can wait much longer.

Choosing the right pot size

Go up by only one size — roughly two to four centimetres wider than the current pot. A much larger pot holds far more wet soil than the roots can use, which is a classic cause of root rot. Always pick a pot with drainage holes.

Step by step

Water lightly a day before, so the root ball holds together.
Ease the plant out by tilting the pot and supporting the stems.
Loosen the roots gently with your fingers if they are tightly circled.
Set the plant at the same depth in fresh, airy mix.
Firm the mix and water thoroughly, then let it drain.

When not to repot

While a plant is flowering — wait until it finishes.
In late autumn or winter, when growth is slow.
When a plant is already stressed or recovering from pests.

If a plant only needs fresh soil and the pot is still the right size, you can top-dress: replace the top few centimetres of mix without disturbing the roots.

Aftercare

Keep the repotted plant out of harsh direct sun for a week and hold off on fertiliser for a month, since fresh mix usually contains enough nutrients to start with.

Frequently Asked Questions

Should I water after repotting?

Yes, water thoroughly once so the mix settles around the roots. If the plant had root damage, wait a few days instead and keep the mix on the dry side.

Can I repot into the same pot?

Yes, if the roots still fit comfortably. Clean the pot, refresh the mix and trim any circling roots.

Why did my plant wilt after repotting?

Some wilting is normal shock. Keep it out of strong sun and avoid feeding for a month; it usually recovers within a week or two.

Pot material and drainage

The material of the pot affects how quickly the mix dries. Unglazed terracotta is porous and wicks moisture away from the roots, which suits succulents and plants prone to overwatering. Glazed ceramic and plastic hold moisture longer, which can suit ferns and other thirsty plants but demands a lighter hand with water. Whatever you choose, drainage holes are non-negotiable: a decorative outer pot works only as a cover around a plain inner pot that has holes.
