This is one of my few gardening successes. I think they've tapped into the septic tank. The first year we were here I dug up a couple of wild roses from the edge of a road and it's a good thing I did because they were sprayed with herbicide the next year and killed. These bloomed the second year but then the next three years they were struck with some kind of killer mildew that caused the buds to fall off, even with diligent spraying. Almost lost the flowers this year but then I tried Neem Oil, which is an organic product but still apparently deadly as it requires a hazmat suit, gloves and goggles to use, and managed to save them. Why is everything so hard? For Pete's Sake they're WILD roses.
