Step by step

1. Choose a plant that can be divided

Part the leaves gently and find the separate growing centres at the surface. Each future plant needs living leaves, a crown and its own share of healthy roots. A larger division usually recovers more readily than a tiny fragment. Choose a period of active growth with mild conditions; do not turn division into an emergency treatment for a plant already collapsing from rot.

2. Release the root ball without pulling leaves

Work over a tray with the compost slightly moist, so roots are flexible rather than brittle or dripping wet. Support the plant at the base, tip the pot and ease out the root ball. Squeeze a flexible nursery pot or loosen its edge; do not yank the foliage. If roots trap a plant inside a rigid pot, release the container safely instead of forcing the crown through.

3. Find the natural divisions

Lay the root ball on the tray and tease away only enough loose compost to follow the crowns down into their roots. Work from the outside inward with your fingers. Spider plants have fleshy storage roots: firm pale roots are useful, not defects to strip away. If you find soft dark roots and a sour smell, stop and assess root rot rather than potting infected sections together.

4. Separate complete rooted plants

Gently pull apart the natural sections while supporting their bases. If a tight bridge of roots prevents separation, put the clump on a firm board and make a controlled cut between crowns with a clean sharp knife. Keep the other hand well away from the blade. Do not slice through every crown to make equal-sized portions: keep a viable growing point and substantial roots on each piece.

5. Set each division at its old depth

Choose a pot that accommodates the roots with modest space for fresh compost around them, rather than a large empty volume. Confirm its drainage holes are open. Add compost, spread the roots without sharply folding them and hold the crown at its previous soil level. Fill around the roots and firm gently with fingertips; burying the leaf bases or compressing the mix hard encourages poor conditions around the crown.

6. Water through and drain completely

Water slowly across the compost until water drains below, then let the pot drain and empty its saucer. Check that settling has not exposed roots; add a little compost if needed without raising it around the crown. The first watering brings compost into contact with the roots. Repeatedly topping up a full saucer does the opposite of helping recovery because it keeps the root zone saturated.

7. Manage recovery by checking the compost

Keep the divisions in bright indirect light away from harsh balcony sun and air-conditioner drafts. Check the compost with a finger before watering and keep it lightly moist, allowing surplus water to escape. Delay feeding while roots recover, and consider any fertiliser already present in the mix. Some temporary leaf droop can occur, but persistent collapse, a soft crown or sour wet compost calls for inspection, not extra water.

Watch the method

Final checks

Each pot drains; every division has a healthy crown and roots; leaf bases remain above compost. Monitor moisture and new growth before feeding.
