Pots and other containers are a great way to display trees on a patio or a rooftop garden and are very useful for growing species that prefer a different soil type from that in the rest of your garden. They are also excellent for tender trees that need to be brought under cover in winter.

Method

1. Use a container that has a depth of at least one and a half times the tree's root ball and a diameter of between one sixth and one quarter of the tree's height. This will supply the tree with a good reserve of moisture, an even soil temperature and plenty of space for the roots to develop.
2. Clean any old container out well with water to remove any disease-causing organisms.
3. Cover the drainage holes with broken crocks and then add a further layer of broken crocks or coarse gravel to a depth of 2.5 cm (1 in).
4. Add some loam-based potting compost enriched with a slow-release fertilizer.
5. If using a stake, insert it into the pot before adding the tree.
6. Fill the container with soil, firming it gently. Take care not to damage the roots.
7. Water thoroughly.
8. Make sure that you keep the tree regularly watered, as it will dry out very quickly in hot weather.
