Water deeply during dry periods, especially in the first year after planting to establish a strong root system. Once established, Scotch Rose is quite drought-tolerant and requires minimal supplemental watering, thriving in average rainfall conditions. Avoid overwatering to prevent root issues.

Minimal pruning is needed. In late winter or early spring, remove any dead, damaged, or diseased wood. To manage size or rejuvenate an old plant, cut back up to one-third of the oldest stems to the ground. Prune after flowering to shape.

Rosa spinosissima can be propagated by several methods. Softwood cuttings taken in early summer can be rooted with hormone. Hardwood cuttings can be taken in late autumn. It also readily propagates from seeds, though germination can be slow and erratic. Division of suckers is another effective and quick method for established plants.

As a hardy outdoor shrub, Rosa spinosissima is typically planted directly into the ground and does not require repotting. If grown in a large container, repotting may be necessary every few years to refresh the soil and accommodate growth, moving to a larger pot or root pruning.
