Ginkgo Tree and lawn

Question

The ginkgo tree in my yard is abut 40 feet tall and produces a lot of leaves that lay on the lawn until gathered. I wait until most of the succulent leaves fall then I gather them. I noticed the lawn under my tree has died. I can easily roll the sod up with a rake. I suspect the toxicity of the leaves may be killing the lawn. Do you have any information about this?

Answer 1

These leaves don't usually harm lawns unless it is excessively wet during the cold months. This can cause a fungal infection that will kill off the lawn. To be safe, I would rake them up as they fall. I would also recommend adding wettable sulfur around the area to kill off anything that could be infecting the soil.
