This is my first time using copper fungicide. I used it on an indoor strawberry plant because they said it's safe for that, and so far so good, I don't see any fungus. It was $9.99 but I got it at a local home and garden so I'm not sure if it'd be more affordable at a bigger store.

This product works WONDERS for my lemon tree! You spray it on, and after a heavy rain you spray again. It is an organic product, and keeps my tree looking healthy!
