watering

Japanese roses should be watered thoroughly about once every 10-14 days. Before watering, manually check the soil to make sure it is completely dry. If it is damp, wait another few days before watering. When watered, provide a deep, thorough watering to ensure that moisture saturates approximately 8-10 inches deep into the soil. After watering, gently press down on the soil to help settle it. Do not allow the plant to become waterlogged, as this can cause fungal diseases and root rot. Make sure to check regularly to ensure sufficient drainage.

sunlight

Japanese rose (Rosa rugosa 'Alba') thrives in full sunlight for at least 6 to 8 hours each day. This plant species does best when grown in an area that has direct exposure to sunlight, particularly during the morning and mid-afternoon hours. When grown in shade, Japanese rose (Rosa rugosa 'Alba') may lack vigor or appear to be weak or leggy. If grown in too much shade, the plant may not produce the desired white flowers.

pruning

Japanese rose (Rosa rugosa 'Alba') should be pruned in late winter to early spring, just before new growth begins. Pruning should be done to shape the plant, remove dead or diseased branches, and promote new growth. It is best to remove only 1-third of the oldest and most vigorous branches to shape the plant and avoid over-pruning. Pruning should also involve thinning out interior branches to promote air circulation and light. This will help to reduce the potential for disease and pests.
