|My tomatoes have these big flat dark spots. Not all of them have this but they have to be destroyed. What causes this. Also my yellow squash which had 6 squash growing, two had the same flat black spots.|
|I don't know whether your veggies have a fungal or bacterial spot so I can't really make a recommendation. Why not take a sample to your local garden center or nursery for diagnosis. Helpful folkx there can determine what the problem is and recommend a treatment/control to you.
Best wishes with your garden!
