So, obviously this post would apply to either very small lawns for spot spraying, or in my case, growing your own bermuda plugs indoors in a greenhouse. Has anybody had experience using Tea Tree, or other essential oils as a fungicide? I read about it online and it's claimed to be effective. However.. I used the prescribed rate in a small spray bottle on my plugs and it looks like it has burned the leaf blades. They suggested a teaspoon per cup of water. Thoughts?
