What are the reasons for black spot on roses and how to deal with it
Black spots on roses are caused by fungal infections. It is necessary to immediately cut off the diseased leaves on the plant and burn them with a open flame to prevent the spread of pathogens. Then, stop watering and fertilizing the roses, and move the plant to a well-ventilated and sunny environment to allow the moisture in the soil to dry out.
1. -- Cause --
Black spots on roses are caused by fungal infections. In the early stages of the disease, small brown spots appear on the rose leaves, which then gradually expand as the pathogen spreads, eventually infecting other rose stems and branches, possibly leading to the complete loss of leaves on the plant.
2. -- Burning Diseased Leaves --
When black spots are found on rose leaves, it is necessary to immediately use disinfected scissors to cut off all the leaves with black spots and burn the cut leaves and fallen leaves with a open flame to prevent the spread of pathogens.
3. -- Stop Fertilizing and Watering --
After destroying the diseased leaves of roses, stop watering and fertilizing the plants and move them to a well-ventilated and sunny environment to promote rapid evaporation of moisture in the soil, thereby reducing the speed of pathogen spread.
4. -- Growing Environment --
In the process of caring for roses, it is necessary to control the temperature of the plant's growing environment, which should not exceed 25 degrees, otherwise it is prone to black spot disease. Also, make sure to place the plant indoors or in an environment with a top covering to prevent the roses from being drenched by rain, which can cause waterlogging.
