If you have a large area to deal with, ensure that the levels are right first and that waterlogging doesn't occur. Major weed problems should be sorted out too.

If the soil is soft from cultivation, tread the whole area and rake to restore the required level. Don't plant into loose soil - roots need firm ground to establish themselves.

Dig a large enough hole to enable the roots to be spread out evenly and loosen the soil at the base of the hole so that water will not collect there and kill the plant.

If planting in spring and a dry spell is likely, fill the planting hole with water and allow it to drain away before planting.
