I live in west central Florida on the coast. I have a 25 x 15 garden for edibles. I have never had trouble before until this growing season. I do cover/cook my plot for several weeks before planting. I amend the soil and use only neem and BT as needed. I started from seed many of my plants. Some I used HD bought that were ahead of my seeds for timing of harvest. All my lettuces and beans (the third pic are the leaves of the beans but they are still producing) are doing well as are my carrots, cucs, tomatoes ect. However, my yellow and zucchini squash are dying. The zucchini did better than the yellow. They looked good for the first weeks and then bam! All are dying. Please help ID the problem (beans too). Thanks in advance, Leslie.
