When to plant

A tree is the perfect solution for filling a gap or screening a building or unsightly view. Container-grown trees can be planted out all year round, apart from when it's very hot and dry, or the ground is frozen. The conditions in autumn are usually ideal for it to thrive - the soil is still warm after summer, and moist from some autumn rain.

What to do

Preparation

• If you have the time, soak the tree well and allow to drain for an hour before planting.
• While this is happening, dig a planting hole twice the diameter of the container and slightly deeper, so that the rootball of the tree sits at the same level as the surface of the soil.

Getting the perfect planting hole

• If the bottom of the planting hole is compacted, break it up with a garden fork, but don't dig it over.
• Do the same to the side of the hole, so new roots can spread into the soil more easily and help the tree establish.

• Take the tree out of its pot, put it in the centre of the hole and check the level by placing a garden cane or stake across the hole - add or remove soil as necessary.

Planting the tree

• Tease out some of the tree's fibrous roots around the edge of the rootball.
• Hold the tree upright, fill the hole with the excavated soil and gently firm with your heel when you reach the top.

Staking and mulching

• Drive a 1m (3ft) stake at a 45-degree angle to the trunk so that they cross, 15cm (6in) above the surface of the soil.
• Firmly fix the tree to the stake with a plastic tree tie, keeping the spacer in the gap between the stake and trunk.

• Water well and spread a 5cm (2in) layer of mulch around the trunk to keep the area free from weeds and help prevent moisture loss.
• Coarse bark chippings are ideal. The layer of mulch should be lower nearer the trunk to divert water towards the growing roots.

Aftercare

• Water newly planted trees regularly during their first year of growth, especially during dry or windy spells.
• In spring, apply a general purpose fertiliser over the root area and renew the layer of mulch.
• Check tree ties often to allow for an increase in girth size.
• During its third growing season, the tree should be firmly anchored and the stake and tie can be removed completely.
• If you have problems with rabbits or other creatures, protect young trees with a tree guard or a custom-built frame made from chicken wire.
