Expert tips
The key tip
Barberry thrives in very well-drained, frankly dry soil: it's its natural habitat. Plant it once, then forget about watering.
The common mistake
Regular watering or planting in rich, moist soil: it slowly rots at the roots and yellows diffusely before dying off.
The pro's trick
Plant it in groups of three to get a denser, more floriferous mass.
Seasonal watch
Autumn (Sept-Oct): birds love its orange berries—perfectly acceptable.
Care
Exposure
Barberry stenophylla thrives in full sun for optimal flowering and compact growth. It tolerates partial shade, but flowers will be less abundant. Prefer a location sheltered from strong winds, which can damage its fine branches.
Watering
Water regularly during planting and the first year. Once established, the plant is very drought-tolerant and requires little water. In case of prolonged summer drought, occasional watering is sufficient.
Soil
Barberry adapts to most well-drained soils. Avoid overly wet or impermeable soils that promote root rot. Light, stony or sandy soil works perfectly.
Pruning
Prune lightly after flowering (May-June) to maintain a harmonious shape. Remove dead or poorly placed branches. Caution: the spines are sharp; wear gloves. The plant tolerates moderate pruning well.
Fertilizing
Barberry doesn't require regular fertilizing if planted in good soil. A compost application in autumn is sufficient. In poor soil, balanced fertilizer in spring can boost growth.
Diseases and pests
This is a robust plant that is rarely affected by diseases. Watch for rust on Berberidaceae in very humid conditions. Aphids may occasionally colonize young shoots. Good air circulation prevents most problems.
Did you know?
Barberry stenophylla is native to Chile and owes its scientific name to its extremely fine leaves (stenophylla = narrow leaves). This shrub was introduced to Europe in the 19th century and became popular in English gardens as an impenetrable defensive hedge plant, thanks to its fearsome spines and spectacular golden spring flowering.
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.
