Expert tips
The key tip
Japanese raspberry fruits on canes from the previous year: cut old canes at ground level immediately after harvest (June). Keep 5-6 vigorous stems per plant.
The common mistake
Pruning at the wrong time or cutting too short: no fruit the following year.
The pro's trick
Install a wire or stake system to spread canes 60 cm from the ground: this makes harvesting easier and reduces fungal diseases.
Care
Light exposure
The Japanese raspberry prefers direct sunlight for optimal fruiting. It tolerates partial shade but fruit production will be reduced. Place it in a location sheltered from strong winds to protect its flexible branches.
Watering
Keep the soil regularly moist during active growth and fruiting periods, without creating waterlogging. During the growing season, weekly watering is generally sufficient depending on climatic conditions. Reduce watering in winter when the plant is dormant.
Soil
The Japanese raspberry appreciates well-draining soil that is slightly acidic to neutral. Enrich the soil with compost or potting soil at planting. Avoid compacted or waterlogged soils that would promote root diseases.
Pruning and training
Prune dead or damaged branches in late winter or early spring. Remove the oldest stems after harvest to encourage new productive shoots. Light pruning maintains a balanced and airy shape.
Fertilizer
Apply balanced fertilizer (NPK) in spring when vegetation starts. An application of well-decomposed compost each autumn naturally enriches the soil. Avoid excess nitrogen which would reduce fruiting in favor of foliage.
Pest and disease prevention
Watch for powdery mildew or rust in conditions of excessive humidity. Ensure good air circulation between branches by thinning the plant. In case of infestation, remove affected parts or opt for suitable natural treatments.
Did you know?
The Japanese raspberry (Rubus phoenicolasius) is recognizable by its fruits covered with characteristic reddish velvety bloom, earning it the nickname 'Japanese raspberry'. In Japan, this shrub has been cultivated for centuries and its tart fruits are traditionally used to make jams and beverages. It's a hardy and generous species that adapts well to temperate gardens and provides a beautiful summer harvest.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
