Origins and peculiarities of berberis
The barberry (berberis), also known asbarberry-, is a genus of thorny shrub with evergreen or deciduous leaves, which belongs to the family of berberidaceae. Between 450 and 500 species of berber are listed today. The best known is called barberry (Berberis vulgaris). The most flowering varieties are generally used for decorative hedges, the thorniest for defensive hedges.
The most common varieties are berberis darwinii, berberis thunbergii and berberis julianae. Depending on the species, the foliage and flowers (in bells or clusters) vary in shade and density ranging from green to purple for the foliage and from pink to white or from yellow to orange for the flowers. The most flowering are the deciduous varieties. Persistent trees are characterized by their thorny, fairly compact leaves.
Berries varying from yellow to dark red follow flowering and appear in spring. It is quite possible to harvest them in early winter (with gloves), but they are very bitter. Most of the time, the fruits of barberry are used to make jams or jellies, combined with other fruits.
Easy to grow and undemanding, berberis can be used in all types of soil, including poor and stony soils. Depending on the species, exposure may vary. Berberis julianae likes shaded areas, for example, while berberis darwinii likes sunny areas.
Rustic, berberis offers good frost resistance (down to minus 20 °) and cold. To promote branching when planting as a hedge, it should be folded down at least a quarter of its height.
To remember : because of the thorns which can be quite sharp, remember not to choose too thorny varieties near your terrace or places of passage in your garden if you have young children.
Berberis supports pruning very well, which makes it a popular shrub for planting hedges. Two sizes in fall and spring are enough to give it a precise shape or height. But beware: wearing protective gloves is essential to avoid injury!
Berberis can be left free in clumps of shrubs, perennials or be planted in isolation. Regular watering every 2 to 3 weeks is recommended outside of cold periods. To keep the soil moist and cool, we usually install a mulch at the bottom.
Diseases and pests of berberis
If they have been planted and installed in optimal conditions, the Berbers know how to be robust and resistant, and do not know particularly enemies in the garden.
Aside from aphids, which can feed on their leaves in the spring, and which you can get rid of with non-chemical treatments, such as garlic manure treatment for example.
