Nothing wrong with you, Ron. They're gorgeous, but look at the soil in that last picture. Looks like dry clay soil to me. They're growing with Nasturtiums in that shot, too. Looks like they do like to dry out. I wonder if an Earth Box would work for them? I grow all my veggies in Earth Boxes, and they have a water reservoir in the bottom, but the top of the soil stays fairly dry (under a plastic cover) and the soil wicks the water up from the bottom. Hmmm . .. or any of the so called 'self watering' containers work on the same theory.
I think the humidity is the culprit in your problems, and of course along with humidity comes fungal growth. We surely have every fungus known to man floating around here in FL and yes, for sure the cinnamon would help with soil-borne fungal growth, but it gets expensive. I use it on my orchids through the summer, and it lasts a couple of months (as long as you can smell it, it's still working, that's my assumption anyway).
I'd bet we won't have many more days with low humidity until October now. Feels a lot more like summer out there today. I'm brewing up some Chamomile tea as I write, and am going to try it out on my little fig tree. It gets rusty fungus every summer, but is clean right now and has figs on it. Spraying with something edible appeals to me a lot! Some people use milk, too but I'm afraid it would stink.
