I don't know if you have ever encountered the situation that the rose bud can not be opened. Two days ago, some flower friends asked this question in the blue demon's readership. I remember that some flower friends have asked similar questions before, so today the blue demon will talk specifically about the reason why the rose bud cannot be opened.

The factors that affect the opening of the rose bud: in the process of the rose, we often encounter the situation that the bud will wither if the bud cannot be opened, so what is the cause of this problem? Blue demon briefly summed up the following five factors.

1. Light rose is a flower that likes light very much. If there is no light for a long time, it will affect the blooming of the bud. This often happens in the rainy season, or after the rose plant is moved indoors. When it is found that there is insufficient light in the rose, the light should be increased in time.

2. Temperature has a great influence on the opening of rose bud. In general, in warm periods such as late spring, it takes only about 35 days for rose to blossom, while when the temperature is low in early spring and late autumn, it takes 40-60 days for rose from pruning to flowering. If the flower bud can not be opened due to the influence of temperature, you can find ways to increase the warmth and put the flowerpot in a warm place in the sun.

3. The rose bud caused by diseases and insect pests can not be opened, and it is most likely to occur in spring and autumn with large temperature difference between morning and evening. Especially in late autumn, under the double influence of disease and low temperature, it will often cause the rose bud to wither when it cannot be opened. The main disease affecting the opening of rose bud is Botrytis cinerea. Spring is generally not too serious, and there are many color spots on the bud. It will be more serious in autumn, directly causing the rose bud to be moldy before it is fully opened.

4. Nutrient deficiency eliminates the influence of diseases and insect pests, and nutrient deficiency is also one of the important factors affecting the bud opening of rose. Some rose varieties are very many, and there will be seven or eight or even more than a dozen buds on a branch. if the buds are not thinned and the fertilizer and water management department is in place, it will lead to the phenomenon that the buds cannot be opened due to the lack of fertilizer and water. This is to think of a pregnant woman who gives birth to multiple births, the nutrition can not keep up, and it is the same reason that each fetus does not grow well. If there are many buds, you must pay attention to topdressing in time to ensure an adequate supply of fertilizer and water.

5. If the variety can rule out the influence of the above four external factors, the rose bud is still unable to open, then it is likely to be the variety problem of the rose itself. Some rose varieties will always remain half-open, this is the style of others.

Common rose varieties that are not easy to open are: goddess of wisdom, song of the sea, red dragon, carnival equivalent. Now the rose with bud delivery, flower friends can go to the store to choose and buy
