Why the rose blossoms less? How to solve it?

Why the rose blossoms less? How to solve it? Please guide the tree rose refers to the artificial gardening skills to develop the rose into a dry, crowned, tree-like tree-like type, which continues the characteristics of many flowers of the rose. However, after many tree roses are planted, they not only do not continue the characteristics of many flowers, but are even so serious that they do not bloom. According to the author's observation, understanding and exploration of tree rose for many years, the reasons are summarized as follows. First, lack of light, poor ventilation, as we all know, rose is a kind of light-loving strong positive flowers, tree rose is no exception. If the plants are given insufficient light, poor ventilation or excessive shade, the branches of tree-like rose will become slender, the leaves will become thinner, and the nutrient accumulation will be poor, which will eventually lead to poor plant growth, small and small flowering, dim flower color, short flowering period and so on. Lack of nutrition or imbalance due to the characteristics of tree-shaped rose flowers blooming many times a year, so the nutritional requirements are relatively higher than other flowers. In the whole growing season of tree rose, fertilizer should be applied several times appropriately, that is, fertilizer should be applied once after each flowering of tree rose, so as to restore the growth of rose plant as soon as possible. In topdressing, we should pay attention to the proportion of nitrogen, phosphorus and potassium, and not only apply a single nitrogen fertilizer or phosphorus and potassium fertilizer, otherwise it will cause symptoms such as only growing branches and leaves or not being able to conceive buds normally. Third, lack of reasonable pruning because the flowering habit of rose is to form flower buds at the top of annual branches, so it is necessary to increase the number of branches by shortening during pruning. However, the more branches, the better. While appropriately increasing the number of branches, it is necessary to adjust the ventilation and light transmission of the plants. In this way, it can not only promote the plant to turn into the state of reproductive growth in time, but also reduce the occurrence of diseases and insect pests. In the flowering and growing season, it is generally treated with light cutting, and then shortened and renewed in winter. The sprouting on the root and trunk of the tree rose should be removed at any time, otherwise more nutrients will be consumed, and the growth potential of the plant will be weakened and the bud and flowering of the plant will be affected. 4. Due to the invasion of diseases and insect pests, the branches and leaves of tree rose plants were damaged, and the effective leaf area of photosynthesis decreased, resulting in the weakening of the whole tree potential. The main diseases are powdery mildew, black spot, etc., which are generally sprayed with 50% carbendazim 800 times solution or 70% methyl topiramate 600 times solution. The main pests are rose three-node leaf peak, rose aphid, Spodoptera litura larvae, etc., which can be controlled with 48% Lesben 1000-fold solution or 1000-fold trichlorfon crystal solution. Fifth, variety characteristics the number of tree-shaped rose flowers is also determined by the variety characteristics, so we should try to select more flowering varieties, such as the crown is abundant rose varieties are easy to blossom. 6. Incompatibility in the later stage is generally formed by grafting and cultivation of tree-shaped rose. Therefore, there are some differences between scion and rootstock, especially the incompatible varieties in the later stage of grafting, the growth state is poor, which will eventually affect plant flowering, some do not blossom, or even gradually die. Therefore, try to select compatible varieties for cultivation. In short, as long as we adjust and solve the above problems, the tree rose will certainly grow longer and better, and the flowers will certainly bloom more and more.
