If planting a large area, ensure that the ground 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. 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 just before planting.

To get plants established in their first year or so, place a watering tube (any pipe or tube will do) vertically in the planting hole, with the top above ground level. Then add water to the tube so that you water the roots, not the ground.
