Planting methods and disease control of purple-leafed Berberis
Planting of Berberis rubrumPurple-leafed barberry has strong adaptability and vigorous vitality, so it only requires extensive management. Usually, the potted plants are divided or transplanted into new pots in spring. If they can be transplanted with soil, it will be more conducive to recovery. Purple-leafed barberry has strong adaptability and is cold- and drought-resistant. It likes sufficient light and a cool and humid environment, and is also tolerant to partial shade. Well-drained sandy loam is suitable for its growth. Purple-leaf barberry is not very demanding on water, but attention should be paid to proper water control. Too wet soil during the seedling stage will cause root rot. In midsummer, purple-leaf barberry needs to be placed in semi-shade for maintenance; watering should follow the principle of watering when the soil is dry and watering when it is wet. Although purple-leafed barberry is relatively drought-resistant, long-term drought is not conducive to its growth. Therefore, when the temperature is high and dry, it is necessary to spray water to cool down and increase humidity. Transplanting can be done in spring or autumn, and it is better if the roots are covered with soil.Pruning and pruning of purple-leaved barberryPurple-leaved Berberis has a strong ability to sprout and appropriate pruning can be done when planting to promote the growth of new branches. Thinning out dense branches or shortening long branches before winter or early spring can make the entire plant shape rounder.Disease control of purple-leafed barberryThe most common disease of Berberis rubrum is powdery mildew. Once infected with powdery mildew, the branches and leaves will wither, affecting the ornamental value and being detrimental to the growth of the entire plant. In addition, powdery mildew spreads very quickly, so once discovered, it should be dealt with immediately. You can spray 1000 times diluted triadimefon on the leaves once a week. Doing this 2-3 times can basically control the disease. |
