    Hello Debbie; I have tried several different things to no avail. The black spots are caused by fungus, typically.

    I use a soaker hose, plenty of fertilizer, and I remove the leaves when they turn black.

    I am sorry that I am not more helpful. Take Care!

    I doubt it ... no luck for me so far even after buying a spray.
