Pieris Plant Care

Blooms on old wood. Should NOT be regularly pruned or cut back. Selectively remove branches as needed to develop the shape you wish. Prefers acidic, moist, well-drained soil and protection from winter winds. Fertilize in winter and early summer with a fertilizer designed for acid-loving plants - a product recommended for azaleas and camellias works well.
