STEP BY STEP

1 Improve the soil by forking in compost. Take out a planting hole at least twice the size of the rootball.

2 Soak the roots in a bucket of water. Remove the ties from the canes and tease out the roots if they’re very dense.

3 Place the plant in the hole and replace the soil, gently firming around the roots. Water thoroughly.

4 Tie the stems horizontally against the supports to encourage the plant to cover the trellis from the base upwards.
