Planting & Care for Blanc Double de Coubert Hybrid Rugosa Rose

Planting

Choose a location with well-draining, fertile soil and full sun exposure. Dig a hole twice the width of the root ball and deep enough so that the graft union is 1-2 inches below the soil surface. Backfill the hole with soil mixed with compost and water thoroughly.

Watering

Water deeply and regularly during the first growing season to establish a strong root system. Once established, water deeply once a week. Avoid overhead watering to prevent fungal diseases.

Fertilizing

Fertilize in early spring with a slow-release granular fertilizer. Repeat every 6-8 weeks during the growing season, following package instructions. Stop fertilizing after mid-summer to prevent new growth that may not have time to harden off before winter.

Pruning

Prune in late winter or early spring before new growth begins. Remove any dead, damaged, or diseased wood, and cut back any weak or crossing branches. Cut back remaining canes by 1/3 to 1/2 of their height to encourage new growth and maintain a compact shape.

Pest & Disease Control

Blanc Double de Coubert is generally resistant to pests and diseases. However, watch for aphids, spider mites, and Japanese beetles. Treat infestations with insecticidal soap or neem oil. Fungal diseases such as blackspot can be prevented by planting in a location with good air circulation, and avoiding overhead watering.
