The common cultivated species is Berberis purpurea, whose branches and leaves are purplish red all the year round. It is an excellent flowering shrub with high ornamental value and is widely used in colored ground covers and hedges everywhere.
Berberis likes light, but is slightly resistant to shade and cold.
The soil requirement is not high, but it grows best on fertile sandy loam with good drainage.
Berberis has strong germination ability and is resistant to pruning.
After the seedlings are planted, the intensity should be trimmed to promote more branches and vigorous growth, which is conducive to molding.
These plants should be properly pruned before the winter solstice and early spring every year.
Prune the branches that are too dense, too long and too weak, and keep the branches evenly distributed into spheres.
Over-densely planted plants should be pruned 1 time within 3 ~ 5 years to achieve the purpose of regeneration and rejuvenation.
Berberis planted in groups in the flower bed should be pruned to make the center higher and the marginal plants lower, so as to enhance the three-dimensional sense of the flower bed.
