How to treat rose soot diseaseA small knowledge of life, about how to treat rose soot disease in flower cultivation, let's learn about it together.How to treat rose soot diseaseYesterday, a flower lover from the Flower Wall Construction Camp asked such a question: "Why did the roses suddenly have many yellow leaves after two days of absence?" Please refer to the picture below.I believe that many flower lovers have encountered this problem recently, where roses suddenly have a large number of yellow leaves without any warning, sometimes even appearing overnight. Why is this?To figure out this problem, we first need to look at the weather changes. It is now autumn, and the temperature is getting lower every day. Sometimes, encountering a cold snap can make it suddenly quite cold, and people are also prone to colds, so it is important to add clothing in time. I caught a cold a couple of days ago when the temperature dropped, but I recovered after timely treatment.We humans are prone to colds in such weather, and for roses, this kind of weather can also make them "catch a cold," which is manifested as a sudden large number of yellow leaves.So flower lovers will find that in autumn, if the temperature suddenly drops one day, roses are more likely to have a large number of yellow leaves, or some planted in windy areas may have many yellow leaves the next day after a night of northwest wind. At this time, many flower lovers may be nervous and unsure of what they did wrong, why the roses suddenly turned like this? In fact, this is a very normal phenomenon and there is no need to worry.How to treat rose soot diseaseIn winter, you will find that roses are less likely to have yellow leaves because they have already adapted to the temperature after experiencing multiple cold snaps in autumn, and they are no longer so sensitive.This kind of yellow leaves caused by sudden temperature changes does not require our attention, we just need to clean up the yellow leaves in time. However, if the leaves of the roses not only turn yellow but also have black edges or tips, then we need to pay attention and deal with it promptly.Because this condition is usually caused by soot disease.The main manifestation of soot disease is that a layer of dark brown to black-brown mold appears on the leaves of roses, and as the condition worsens, the mold layer becomes thicker and takes on a sooty appearance.If not treated in time, the pathogen will overwinter in the affected area in the form of mycelium, conidiomata, and cleistothecia, and reproduce and grow again the next year, causing extensive disease.Therefore, if roses have soot disease, they must be treated promptly. You can spray with mancozeb or thiophanate-methyl, once a week for 2-3 consecutive times, which can basically cure the disease. After the leaves fall in winter, do a comprehensive garden cleanup. For specific cleanup methods, please refer to the book "How to Raise a Bursting Rose from Scratch" by Green Plant Enthusiast, and I will not elaborate here.Roses are flowers that are easy to keep alive but difficult to cultivate well. Although the management is quite complicated, when the flowers bloom, you will feel that everything is worth it! Life is about struggling!The above specific introduction of how to treat rose soot disease introduced by the Green Plant Enthusiast website [www.lvzhimi.com] hopes to bring some flower knowledge to flower enthusiasts.
