Lawn care

Asked June 20, 2017, 8:39 AM EDT

Could a fungus be the cause of the small dead patches of grass in my backyard? We put down Grub-x and the dead patch does not pull up easily so I don't think it is grubs. Patches are about the size of a hand. The dead areas are not depressed into the soil, just grass on top is dead. Can't detect any white stands or webbing in the areas. No pets and have not been watering the lawn as we have gotten rain at least once a week here in Carroll County. Happened last year too, but in the spring it always comes in and looks great and then by early June we have the problem again.

This wcould be brown patch, a fungal disease associated with warm nighttime temperatures and spring fertilization. Please look over our webpage about brown patch, noticing the leaf blade lesions:

Note that fertilizing in the spring makes the severity of brown patch much greater. Here are links for good Maryland fertilizing guidelines and practices: Fertilize in fall.

Brown patch does not kill the turf roots, fortunately. That is why your lawn keeps recovering.


Thank you so much for the quick response. Now I know what is going on with my lawn and can make sure it doesn't happen again next year. This is a great service y'all do!!!

You are very welcome. Don't hesitate to be in touch again if you have additional questions.
