Rhodies have a terrible fungus
So my rhodies are really bad. I have two 8 footers that are badly diseased with some sort of blight like fungus. They need some help.
I just dead-headed them, so they are fairly cleaned up at this point, and this is an opportune time for a first fungal treatment to try and save them.
I was thinking of using a peppermint oil based spray, perhaps mixed with some fresh raw garlic juice. (both natural anti-fungal). Any thoughts on this, or do I need to go more commercial full strength?
