Water rugosa roses regularly, especially during dry spells and when establishing. Aim for consistent moisture, allowing the soil surface to dry slightly between waterings. Deep watering encourages stronger root development. Reduce frequency in cooler weather or when the plant is dormant.

Prune rugosa roses in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. Can be pruned lightly after flowering to shape the plant and encourage a second flush of blooms. Avoid heavy pruning, as they flower on old wood.

Propagate rugosa roses by softwood cuttings taken in early summer, or by layering in autumn. Seed propagation is also possible but may not result in true-to-type plants. Cuttings should be treated with rooting hormone and placed in a moist, well-draining medium.

Repotting is generally not necessary for established rugosa roses in the ground. If growing in containers, repot every 2-3 years in spring or autumn to refresh the soil and provide more space. Use a good quality potting mix amended with compost.
