From time to time, you may find that you need to move a tree; either you may need to move it as a result of a new garden design or it doesn't seem to be thriving in the position it is in. The younger and smaller the tree, the more likely it will re-establish itself successfully. Any trees taller than 2.5 m (8 ft) or with a trunk larger than a hand grip may have more chance of success if moved by a specialist arborist.

Preparing the Site

• In early autumn, a full year before you plan to move the tree, mark out the optimum root-ball diameter for the tree. This will be approximately one third of the tree's height.
• Dig a trench along the outside of your line about 30 cm (12 in) wide and 60 cm (24 in) deep.
• Mix the removed soil with large quantities of well-rotted organic matter.
• Dig around the root ball, undercutting the roots and severing any large, coarse roots. This will stimulate the growth of fibrous "feeder" roots, which will help the tree establish successfully after transplanting.
• Replace the soil mixed with organic material into the trench.

Lifting the Tree

• The following autumn, tie up any low branches to the main trunk to protect them from damage and to keep them out of your way.
• Dig a new trench just outside the one made the previous year.
• Carefully fork away the soil around the root ball removing a small amount at a time to avoid damaging the fibrous feeder roots. Continue until the root ball is of a size and weight that you can manage.
• Use a spade to cut through any roots beneath the root ball, so that it is completely separated from the surrounding soil. Cut back any awkward roots with secateurs.
• Roll up a length of hessian or plastic sheeting. Tilt the tree to one side and slide the material under the raised side of the root ball.
• Carefully tilt the tree the other way and pull the sacking through underneath it. The root ball should now be sitting on the centre of the material.
• Gather the corners of the sacking and pull them together around the root ball so that it is completely covered. Tie the material together securely with rope. This will hold the root ball together and prevent the roots from drying out while you move the tree.
• Tilt the tree again and slide two planks underneath it to act as a ramp. You may need to lever the tree onto the ramp, or pull it on using the rope. Ease it up the ramp out of the hole and move the tree carefully to its new position.
