How to Grow

The best time to establish your Rosa ‘ZLEMarianne Yoshida’ OSO EASY HAPPY PETIT PINK is when dormant, either in early spring or fall. Select a planting site that receives full sun, although it can tolerate part shade; note that full sun maximizes flowering and disease resistance. This Shrub rose thrives best when planted in medium-moisture, slightly acidic, well-drained garden loams.

When establishing the plant, water deeply and regularly, prioritizing morning watering to allow foliage to dry before nightfall, as overhead watering should be avoided. Good air circulation is crucial for managing foliar diseases. Applying a summer mulch helps conserve soil moisture, keeps the root zone cool, and controls competitive weeds around the base of the plant.

To encourage continuous blooming from your Rosa ‘ZLEMarianne Yoshida’ OSO EASY HAPPY PETIT PINK, be diligent about removing spent flowers throughout the season. Prune as necessary in late winter to early spring to shape the plant. In colder climates within its range, such as near St. Louis, providing winter protection for the crowns is recommended for survival. Always clean up and destroy fallen leaves both during the growing season and as part of the final dormant cleanup to minimize overwintering pathogens.
