What to do if Hydrangeas get Grey Mold Disease
Main text core guide: This article discusses how to deal with grey mold disease in hydrangeas, as well as the causes and solutions for grey mold disease in hydrangeas in terms of green plant maintenance. Detailed content is shared below.
In spring and summer, green plants successively awaken from dormancy and enter the growing period. Plants grow fastest in spring, influenced by local temperatures. Most plants sprout first and then grow leaves, and by summer, they can complete flowering. During growth, plants may encounter various irresistible diseases, which have a significant impact on them and must be dealt with promptly.
Grey mold disease is the most common disease encountered in home gardening. It is often seen on roses and hydrangeas. Due to some other factors, the leaves turn from green to gray, and the originally green leaves look as if they have mildewed. There will be some fine villi on the leaves, which is actually the manifestation of mold.
Grey mold disease is caused by many factors, with the main factor being overly moist potting soil and poor air circulation, leading to the growth of mold. Mold invades the leaves of the plant, causing grey mold disease. The leaves will gradually turn gray and eventually wither, preventing the growth of new leaves and severely affecting growth and flowering.
What to do if Hydrangeas get Grey Mold Disease
Taking hydrangeas as an example, the southern regions of China have humid air and high rainfall, which easily trigger grey mold disease. From March to April each year, it is the germination period of hydrangeas. During this stage, hydrangeas grow new leaves and tender buds that are easily affected by grey mold disease.
When the leaves of hydrangeas show symptoms of grey mold disease, what should we do to solve it?
There are two ways to solve this problem. The first is to remove the affected leaves promptly when they show signs of disease. Do not keep the diseased leaves. Manually remove them and discard them immediately. This is the easiest solution and works well at the root.
The second is to spray pesticides. Pesticides are essential for home gardening, especially fungicides like carbendazim, which can effectively remove grey mold disease. Buy a few packets online for a few dollars each, which is very practical. A packet of pesticide, used according to the specified ratio, can last for a long time. Dissolve it in water and spray it directly on the leaves of the plant, with an interval of 3 to 5 days between sprays.
