When planting blackberries, they need to be pruned during growth, flowering, fruit and dormancy. Pruning during the growth period can inhibit the growth of the main stem. Pruning during flowering and fruiting can help plants save nutrients and increase the number of flowering and fruiting. Pruning during dormancy can improve the growth rate of plants. Pruning blackberries in different periods has different effects on plants. Growers need to prune them scientifically according to different periods. 1、 When to prune blackberries? Blackberries should be pruned effectively for many times, generally in four stages: growth period, flowering period, fruit period and dormancy period. They grow faster in spring, so they usually prune the plants after the rain. When flowering, you can cut off the sick branches and leaves and withered buds on the plant. During the fruiting period, the branches and leaves that grow too dense or too long can be cut off. In the dormancy period, it is necessary to cut off the poorly growing branches and leaves and the over dense branches in order to improve the growth rate of plants and the ventilation between plants. 2、 How to prune BlackBerry 1. Growth period: during the growth period of the plant, it is necessary to select an appropriate time to cut off the buds and leaves growing on the top of the plant. In order to avoid the main stem growing too high, make the plant grow more lateral branches and improve the flowering and fruiting rate.
2. Flowering and fruiting stage: in the flowering stage of BlackBerry tree, the branches and leaves suffering from diseases and insect pests and withered flower buds on the plant shall be cut to make it have sufficient nutrients, open more flower buds, bear more fruits and increase fruit yield. Because they will consume a lot of nutrients when they bear fruit, they need to cut off too dense branches and leaves to save nutrients.
3. Dormancy period: during their dormancy period, it is necessary to cut off the poorly growing branches and leaves to improve the growth rate of the plant. At the same time, it is also necessary to cut off the branches that grow too dense or too long, save nutrients, improve the ventilation between plants, so that the plants can grow healthily and pass the winter smoothly. （HeiMeiShenMeShiHouXiuJian）
