I have three ash trees in my yard. One of them is a large tree that shades the east side of my home. I would miss it if it had to come down. I started using the Bayer granules this spring. In the town about 10 miles from me trees are getting hit pretty hard. My 5 acres is surrounded by crop land with no woods except for fence lines or drainage ditches. I am guessing the nearest ash tree to me is a few miles away. So far my trees look fine. I am wondering if the distance to other ash trees is helping me. Also how effective are the Bayer granules? Any experience with emerald ash borer. Thanks.
