BARE-ROOTED, broad-leaved trees should be planted before the end of the month. Native species such as birch, alder, whitebeam, hawthorn, hazel, oak, rowan and ash attract more wildlife than introduced species and ornamental garden varieties. However, almost any tree will vastly improve the garden. Before planting, make sure that the eventual size of the mature tree won't crowd or unduly shade your garden - or your neighbour's.
While you are preparing the planting hole cover the tree roots with sacking or polythene so they don't dry out. Dig a hole at least six inches deeper and 24 inches wider than the root ball. Loosen the soil in the bottom of the hole. Drive a support stake firmly into the hole at a slight angle.
Spread out the roots and place the tree in the hole, on the side of the stake away from prevailing winds; plant it at the same depth it was growing at previously. Fill under and around the roots with good soil mixed with lots of organic compost. Gently firm the soil and attach the tree trunk to the stake with tree ties at top and bottom.
Water very generously. Continue to water during dry spells for at least a year.
