Fertilizer

Japanese Pieris benefits from regular, light applications of a balanced, slow-release fertilizer in the early spring. Avoid heavy applications of fertilizer, as excessive nutrients can cause damage to the plant.

Soil

It thrives in acidic, well-draining soil with high organic matter content. Incorporating organic mulch around the base of the plant helps maintain moisture and enhances the soil structure.

Pruning

Pruning is generally done after flowering to maintain the desired shape and size. It is recommended to remove any dead or damaged branches and to prune lightly to encourage bushy growth.
