This is the 892nd day of the Blue Devil's daily original article.

Rose Culture Series: the 89th

Blue demon has been sharing articles about rose farming for the last two or three months. If you have been reading blue demon's articles, you should be quite sure about rose farming.

However, for some novice flower friends who occasionally read blue demon articles, there will still be a lot of problems in the breeding process of rose. Today, the blue demon is talking about the blind bud of the rose, which is also the question raised by the blue demon reader group of flower friends.

In this flower friend's rose, there are a large number of blind buds, and the leaves look very healthy, but they grow blind buds and no buds are produced.

From the photos, we can also see that the leaves of the rose look very healthy, and there is no obvious disease and insect pests, and lack of fertilizer. So what is the problem that causes this phenomenon? To find out the reason, you have to review the maintenance process. Rose will not sprout blindly for no reason, it must be something wrong with our maintenance methods.

The possible reasons for the emergence of blind buds: first of all, blue demons to understand, resulting in several possibilities of blind buds. 1. Lack of fat: on the surface, there is no lack of fat yellow leaves, thin performance, the overall listen to health. But the blue demon reminds everyone: all the blind buds, the most fundamental cause is malnutrition, how to cause malnutrition, is the key to solve the problem.

It is obvious that there are no obvious symptoms of nitrogen deficiency and element deficiency in this rose. Our reader Hua you also applies Huaduoduo No. 1 once a week. (all I look healthy) 2, lack of light in addition to insufficient fertilization, lack of light will lead to lack of rose photosynthetic cooperation rate, and malnutrition, but our flower friend is outdoor farming, it is obvious that there is no lack of light. 3. Diseases and insect pests

Diseases and insect pests will lead to the weakening of rose plant growth and the emergence of blind branches, but it is obvious that our flower friend's rose has no diseases and insect pests. 4. Element deficiency

Rose flowers have more demand for some medium elements, especially in potted plants, if the soil is single, it is easy to appear the phenomenon of element deficiency. In general, severe deficiency will have a performance in the leaves, but if there is a slight deficiency, it may not be obvious. The frequency of Huaduoduo No. 1 is relatively high, and there is no shortage of three major nutrients, so transpiration looks healthier. But if there is a lack of calcium fertilizer.

Calcium will directly affect the growth of the bud point, and the top of the rose branch belongs to the bud point, if there is a phenomenon of calcium deficiency, it is also normal for branches to grow and appear blind buds.

In addition, rose branches consume more nitrogen fertilizer in the process of growth, but more phosphorus and potassium fertilizer is needed when flower buds are needed in the later stage of branch growth, and Huaduo No. 1 is a general fertilizer for growth. if the base fertilizer is also low in phosphorus and potassium, then there is a possibility of insufficient phosphorus and potassium fertilizer.

Therefore, the blue demon's suggestion is: first cut the blind branch gently, can take a leaf or 2 leaves cut off, and then add phosphorus and potassium fertilizer (you can use Huaduoduo 2), and properly supplement calcium fertilizer. Calcium fertilizer can be foliar sprayed with calcium gluconate diluted.
