Japanese rose can be controlled by applications of herbicides in a planned treatment programme. The herbicide can either be sprayed onto the leaves, however for complete eradication excavation is the only effective way to get rid of all parts of the plant, most importantly its roots.

Japanese rose is listed on Schedule 9 of the Wildlife & Countryside Act 1981, as such it is illegal to allow it to spread either onto a neighbour’s property or into the wild. Since it was first introduced into the UK in the mid 19th century it has spread voraciously.
Japanese rose grows via a powerful underground root system. These rhizomes can break off and, as it thrives by the sea, it can easily spread by water to new areas.
The hips (seed pods) from this species have been known to float for up to 42 weeks, in both freshwater and seawater, its seeds remaining viable after that time. It also alters the soil nutrition, which can cause problems for inhabitants.
SCIENTIFIC NAME: Rosa rugosa
ORIGIN: East Asia
Japanese rose is a suckering, deciduous shrub with many slim thorns along its stems and bright fuchsia pink flowers, though it can have white flowers.
Prefers loamy, well-drained soil in partial shade, though is happy in most soil types and will also tolerate full shade. The flowers will dwindle if in full sun. Often found on coastal areas, its root systems cause the sand dunes to become too stabilised making the habitat more difficult for plant and animal species to survive.
Can out-compete native species if left to grow uncontrolled.
Japanese rose presents no physical danger to either humans or animals.
