Another natural fungicide is ground cinnamon. Just sprinkled in the dirt.
This looks like the plant that grows around (has taken over & even goes up the wall a bit) the front of a local re-sale store here. It is under the overhang so prob stays rather dry & gets full sun. I brought some home with me last year with the hopes it would spread thru my front bed. I'm guessing it got too much water and disappeared on me.
