Ensure good drainage by putting a layer of broken terracotta pot or large stones over the holes in the base of the pot.
Put a layer of an equal parts mix of John Innes no.3 and multi-purpose compost in the base of the container and add a handful of slow-release fertiliser granules. Mix them into the compost.
Knock the plant from its pot and set it in the container. Add more compost under the plant to raise the top of the rootball to about 2cm - 3cm below the rim of the container. Fill around the rootball with more compost mix, firming it in layers as you fill.
Aim for the finished compost level to be 2cm - 3cm below the rim of the pot. This will allow you to water the plant thoroughly.
Fill in any gaps with compost. Water well and allow to drain.
