Lawn Diseases after Winter...
In Ohio, common lawn diseases that can occur in late winter and early spring include:
Snow Mold: This is a fungal disease that occurs under snow cover or in areas where snow has recently melted. It causes circular patches of dead or yellowed grass, with a gray or pinkish web-like substance on the blades.
Red Thread: This disease is caused by a fungus that thrives in cool, damp conditions. It appears as reddish-pink threads on the blades of the grass, and can cause the grass to become thin and weak.
Dollar Spot: This disease is characterized by small, circular brown spots that are about the size of a silver dollar. It is caused by a fungus that thrives in warm, humid conditions.
Spring Dead Spot: This is a fungal disease that can affect Bermuda grass and Zoysia grass in Ohio. It causes circular patches of dead grass that can be several inches in diameter.
Rust: This disease is caused by a fungal infection that causes orange or brown rust-colored spots on the grass blades. It can weaken the grass and make it more susceptible to other diseases.
If you notice any signs of these lawn diseases, it's important to take action to prevent them from spreading and causing further damage. Treatment options vary depending on the specific disease, but may include fungicides, cultural practices, and adjustments to your lawn care routine. Fungicides can be applied to the affected areas to kill the fungus and prevent it from spreading. Cultural practices such as aerating, dethatching, and improving soil drainage can help promote a healthy lawn and reduce the risk of disease. In addition, adjusting your lawn care routine to ensure proper watering, fertilization, and mowing can also help prevent lawn diseases from occurring. If you're unsure of the best treatment options for your lawn, consult with a lawn care professional for expert advice.
