Summer miss this point rose a year white can not bloom is a problem

Many rose lovers report that their rose has grown big and strong, with many branches and leaves, but only a few flowers bloom every year. The fertilizer given is also very sufficient, and the light is fine, so why can't the pot burst? In fact, a large part of the reason is related to summer pruning, so I will talk to you today about how to prune the summer rose.

When it comes to pruning roses, many people will know that branches are pruned before sprouting after dormant winter roses. But why is summer pruning? Then let me tell you about the necessity of pruning summer roses. Rose reached the peak of flowering in late spring and early summer, most varieties of rose entered the period of growing branches and leaves, at this time flowering is less, and even some varieties no longer bloom, only long branches and leaves. With the rise of temperature and the advent of the rainy season, the rose will enter the fastest growing period in late July and early August (North China). If the growth is not controlled, the plant type of rose will grow too long, the accumulated nutrients will be used for the growth of branches, as well as poor ventilation caused by dense branches, lack of daylighting and other conditions will affect the flowering in the second year. Therefore, it is necessary to prune rose branches at the height of summer.

How to do summer pruning? The main thing is to master the following three principles to make a good summer pruning: the first is to remove the weak and stay strong. After a year of growth and flowering, many weak branches will appear, the leaves are yellow, the leaves are small, and the branches are hard. So when pruning, you have to cut off these weak branches. In addition, the branches infected with diseases and insect pests were pruned in time. Because the rose blossoms on the branches of the previous year, it is necessary to complete the replacement of new and old branches in summer, and this year's new branches will be the main force for next year's flowering.

The second principle is to alienate the crossed branches and the co-directional branches. Rain Water is abundant in summer, and the rose grows excessively, which leads to the cross growth of many new branches. when the wind blows the branches back and forth, the contact part of the cross branches will be infected by abrasion, so one of them should be cut off. In addition, multiple branches growing in the same direction at the same time, especially those that are too close, should be alienated to ensure adequate lighting and ventilation.

The third principle is to use different pruning methods according to different varieties of rose. For example, for large rattan rose, summer pruning should not be pruned, which will only cause more side branches to sprout, which is not conducive to winter pruning. But for shrub roses and weak roses, more lateral branches can be promoted by pruning, and more flowers can be produced in the second year.
