Among few diseases, the Indian hawthorn is highly susceptible to Entomosporium leaf spot. This leaf spot disease is very common in many shrubs, including quince, red tip photinia, pear, and Indian hawthorn. Initially, causes cosmetic damage but it can get severe at times.
This disease affects right into the leaves causing red spots and leading them to die eventually. Hot and humid weather is favorable for the thriving of Entomosporium maculatum. Therefore, if it rains heavily in spring, it creates the perfect weather condition along with the heat to encourage the disease.
Especially, when the temperature ranges between 60 to 80 degrees Fahrenheit and the leaves are wet for long periods, the disease surpluses. If the leaves are wet for 12 to 24 hours, the fungal spread will double overnight.
Moreover, this fungal disease encourages further infections of the shrubs. It makes them easily vulnerable to cold and insect infestations. Again, stagnant soil water also encourages the spread of Entomosporium leaf spots.
Nonetheless, the spots that the disease leaves are very prominent on the leaves. The splotches are maroon in color and spread the infection. At a certain point, the spots cover the entire leaf by enlarging and getting darker.
- Initially pick out the infected leaves and destroy them far away from the garden. Also, you can zip them up and then dispose of them in the trash.
- Use resistant cultivars.

Root rot is also a result of your plant growing in poorly drained soil. Affecting the whole root system of the plant, the fungus infects the stems and leaves.

However, you can recognize the disease once you know about the symptoms. If the plant is affected, expose the wood beneath the bark, you will see discolored and vertical streaks on the surface.

This disease can attack even the woody portion of Indian hawthorn. When you scrap the wood, you will notice discolored wood with multiple streaks.
Once the bacteria affect your plant, it makes the plant look like it is burnt by fire. Exactly that is why this disease is known as fire blight. Also, exactly to the properties, this bacterial infection is a systemic disease. It makes the shrub look dead.
