How to grow Japanese Rose
Planting
Exceptionally tough — it takes salt wind, sand and neglect, and makes an impenetrable low hedge. Plant bare-root in winter about 60 cm apart for hedging.
Pruning
Very little required. Shear a hedge over in late winter, and cut old stems out at the base occasionally. Do not deadhead if you want the large tomato-like hips.
Propagation
Rooted suckers in winter, or hardwood cuttings in autumn.
Pests and diseases
Notably resistant to blackspot and mildew, which is a large part of its appeal. It reacts badly to glyphosate drift, showing distorted narrow growth.
Value to wildlife
Single forms are heavily worked by bees, and the hips are large and persistent. The dense prickly growth shelters nesting birds.
Notes
It suckers strongly and is invasive on sand dunes and coastal habitats in parts of Britain and northern Europe. Do not plant it near dunes or where it can escape into the wild, and be prepared to remove suckers each year in a garden.
