Planting & Care Guide

Ideal Location

Choose a spot with morning sun and afternoon shade or full partial shade to protect ‘Royal Red’® from scorching. Ensure the site has rich, well-drained soil amended with organic matter. Avoid waterlogged areas to prevent root rot.

Watering

Keep soil evenly moist, especially during establishment (Plantgoed P12 stage) and hot spells. Mulch around the base with compost or bark to retain moisture and regulate root temperature. Do not allow the soil to dry out completely.

Pruning & Maintenance

Prune immediately after flowering in late summer or early autumn. Remove old flower heads and trim back one or two pairs of healthy buds to encourage new stems. Avoid heavy pruning into old wood, as ‘Royal Red’® blooms on older cane tips. Apply a balanced, slow-release fertilizer in spring to boost bloom production.
