I'm so mad at myself. Found a recipe online for an organic fungicide/soft insect spray. I suspected common blight on my beans and I have aphids on most plants in the garden. Spray was 1 T. oil; 2 T. baking soda; few drops of Dr. Bronner's soap; 1 qt. water. Came out the next day and *everything* has brown spots that look like a burn (except the tomatoes), and the edges of the bean leaves are all curled in.
I'm trying to console myself with the fact that the squash plants are still getting bigger (no flowers yet), the beans have flowered, the baby tomatoes still look good, and the cuke plants are rapidly outgrowing their trellis.
