In all situations, organic matter such as well rotted pine chips, peat or leaf mould helps improve soil texture, especially that of heavy clay or very light sandy soil, it provides nutrients and maintains acidity. Organic matter based on animal waste is unsuitable as it can scorch roots and cause plant death.

Open Garden
Allow 1.5m diameter space around each highbush plant, or .75m for half high varieties.
Excavate over the full diameter down to 30cm (1ft), and mix organic matter with the existing soil.
Before planting, ensure soil is moist.
Remove plant from its pot and place in the ground so that the final depth of the plant after firming is no higher than the level of the soil. Water well.

Container Growing
Your plants will normally have arrived in 2 litre pots and can be gradually moved up in stages over the years until they reach ½ beer barrel size containers (24 inches or 60cm).
Any container should have adequate drainage and preferably be raised off the ground slightly to allow water to drain away.
Plant your blueberry in ericaceous compost or peat.
Water retaining gel sachets can be added to reduce the need for frequent watering in the summer.
A dressing of pine bark mulch to 2 inches will reduce watering further. Water well after planting.
