Expert tips
The key tip
Berberis julianae accepts poor soils as long as they're well-drained; water sparingly after planting.
The common mistake
Thinking a young shrub needs watering in summer and overdoing it, which causes rot or decline.
The pro's trick
Let it grow freely for the first few years if you want a dense, natural-looking defensive hedge.
Care
Exposure
Juliana barberry prefers full sun for vigorous growth and abundant flowering. It also tolerates partial shade, but will develop a less dense habit. Avoid overly shaded locations that would slow its development.
Watering
Once established, this barberry is very drought tolerant and requires little irrigation. During the first year after planting, water regularly to encourage root establishment. After that, occasional watering during heat waves is sufficient.
Soil
Barberry adapts to most soils, including poor or chalky ones. Well-drained soil is preferable to prevent root suffocation. Light soil and even gravelly soil suit this robust species perfectly.
Pruning and shaping
Light pruning after flowering (late May) helps maintain a compact habit and encourages branching. Trim branches that protrude or cross over each other. Be careful of its sharp spines: wear protective gloves when handling.
Fertilizer
This shrub is not demanding. A light annual application in spring in the form of compost or organic fertilizer is sufficient. On fertile soil, fertilizer is unnecessary and can even promote foliage at the expense of flowering.
Health and pests
Juliana barberry is very resistant to common diseases. During particularly humid summers, watch for powdery mildew or rust attacks, which are rare but possible. Good drainage and airflow generally prevent any fungal problems.
Did you know?
Juliana barberry is named after British botanist Auguste Henry Julian, who discovered it in China in the early twentieth century. This spiny shrub was traditionally used in defensive hedges in Asian gardens, and its bright yellow wood once contained compounds used in dye-making and highly prized for the production of natural colorants.
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.
