I have only five 4×1.50 yard boxes of vegetables. Phyalis, Tomatoes, Raspberries that are 2.7 yards tall ? , Cabbage, Peas, Beans, Parsnips, Salads, Peppers, Cucumbers, Beets and some melons. Of course, not much of each. But I have no diseases, or at least I do not see any ? The leaves are all very green. Some cabbage leaves have some holes eaten but not very much. This year I bought city compost and I added seaweed and EM, that is all. Perhaps there are diseases that I do not see since I am a beginner ? Raymond living in Pau, France.
