Soil & repotting

Mix the right blend and know exactly when to size up the pot.

‘Potting soil’ from a bag is a starting point, not a finish line. Most houseplants want a mix that holds some moisture but drains fast.

How to repot without the stress

  1. 1

    Size up gently

    Choose a pot just 2–4 cm wider — too big and the soil stays soggy.

  2. 2

    Loosen the roots

    Tease the root ball apart so new roots grow outward, not in circles.

  3. 3

    Fresh mix below & around

    Sit the plant at the same depth as before and fill the gaps.

  4. 4

    Water in

    Water thoroughly to settle the soil, then hold off feeding for 4–6 weeks.

ℹ️

Best time to repot: early spring, just as new growth begins. The plant recovers fastest then.
