Site and situation
The colourful new shoots can be damaged by spring frosts, so plant pieris with shelter to the east to prevent early morning sun from scorching frozen shoots.
Choose a site with neutral or acid soil. Neutral soils can be made more suitable by working in composted pine bark.
Pieris also enjoy plenty of humus. Even on acid soils, forking in limefree soil conditioner is helpful.
Adding rhododendron fertiliser is also beneficial.
A sunny site – or one in partial shade – is ideal. In full shade growth may be spindly and flowering sparse.
