Berberis rubra, a cultivated variety of Berberis, is an excellent variety and deciduous shrub cultivated in Europe in the 1920s. Branches are clustered, young branches are purplish red or dark red, and old branches are grayish brown or purplish brown.

Leaves entire, rhombic or obovate, purplish red to bright red, slightly lighter on the back. It blooms in April and the flowers are yellow. Slightly fragrant. The fruiting period is September-165438+1October, and the fruit is oval and bright red. The fruiting period is long, and branches can still be covered after defoliation.

Plant early in spring and prune hard. It is best to initialize the soil surface before the sap flows out (from March 10 to April 10 in the north).

After planting, step on it, spray it, flood it, cut off 2/3 from the upper part of the branch, and water it every 3 ~ 5 days. When the sandstorm is heavy, spray 1 2 times a day, and after the third irrigation, cultivate the soil and seal the roots. After planting, wind barriers should be set up to avoid wind damage to newly sprouted fibrous roots. After the windy season, most of the new buds have germinated (about 20 ~ 30 days), and the windbreak barrier is lifted by irrigation for 2 ~ 3 times.

Fertilization should be carried out in the rainy season of that year, and foliar fertilizer can be sprayed in weak places to promote the growth of branches, leaves and roots, so as to achieve good ornamental effect. Planting in summer and autumn should be later, pruning should be less and lighter, and it is best to do it after the branches are lodging and semi-lignified in that year. At this time, it is the rainy season, with sufficient water supply and high soil temperature, which is conducive to rooting.
