Soil: Moist, well-drained, slightly acidic soil is ideal. Improving the planting area with organic matter enhances structure and moisture retention.
Planting Instructions

Soil Preparation: Mix organic matter or ericaceous compost into the excavated soil to improve fertility and acidity.
Planting: Position the shrub so the top of the root ball sits level with the soil surface, then backfill and firm gently.
Water After Planting: Water thoroughly to settle the soil and support early establishment of Skimmia japonica ‘Double Diamond’.
Watering Requirements
Establishment Phase: Water regularly during the first growing period to encourage deep root development.

Feeding

Optional Feeding: Additionally, a light feed after flowering can help maintain vigour throughout the year.
Pruning and Maintenance

After Flowering: Light tidying can be carried out once blooms fade to maintain a compact form.
Mulching
Spring Mulch: Apply leaf mould or compost around the base to retain moisture and suppress weeds.
Protective Mulch: Mulching also helps protect shallow roots and improves long-term soil condition.
