A large part of my lawn will now grow nothing. There was pachysandra, hostas, etc for 40 years. Ihave 3 other shady plants. If I use copper to kill a possible fungus, will it hurt the tree?

See our previous response to you in Question #445339.
We do not recommend a fungicide unless you know what you are spraying for. It is possible that you are dealing with cultural, environmental issues and not a fungus.
Please send us photos of the site and affected plants so we can see what you may be dealing with.
