If you’ve noticed that Indian Hawthorn shrubs around Alabama seem to be thinning out or dropping leaves early, you’re not imagining things. Hawthorn blight, a fungal disease caused by Entomosporium mespili, is making these once-popular landscape shrubs nearly unplantable in our climate.
What Is Hawthorn Blight?
Hawthorn blight, also known as Entomosporium leaf spot, is a fungal disease that affects Hawthorns and related species. It starts as small reddish or purple spots on leaves, which expand and merge over time. This leads to:
- Yellowing leaves.
- Premature leaf drop.
- Bare, thinning canopies by mid-summer.
The disease spreads easily through rain splash and humid conditions, making Alabama’s climate the perfect environment for repeated infections.
Why It’s a Problem in Alabama
Because Entomosporium thrives in humid, wet conditions, Alabama homeowners face repeated infections every year. Even with fungicide treatments, the disease can be challenging to control. Over time, trees weaken, become unsightly, and lose their intended landscape value.
The result? A shrub that constantly looks stressed, drops leaves, and requires ongoing attention.
Are There Resistant Hawthorn Varieties?
You may have heard of “resistant” Hawthorn varieties. While there are rumors of cultivars with improved tolerance, these have not shown consistent success in Alabama’s environment and high humidity. At this time, we do not recommend planting new Hawthorns due to the high risk of disease.
What If You Already Have Hawthorns?
If you currently have Hawthorns on your property:
- Monitor for leaf spots and leaf drop starting in spring.
- Rake and dispose of fallen leaves to reduce fungal spread.
- Avoid overhead watering to limit moisture on foliage.
- Prune for airflow to help leaves dry more quickly.
While these steps can help, they will not eliminate the disease entirely. If your shrubs are heavily affected year after year, it may be time to consider replacing them.
