Hi!
Today on our tomato and bean plants, I found many yellow leaves with black spots. Some are wilted, some aren't. I removed those leaves, disinfecting the cutter between plants. The cuttings were put in the sealed trash instead of composting. The neighbor's maple trees all have black spots, but those leaves aren't yellow.
Note that some tomatoes are in raised boxes and the dirt dries out daily. Some are in the ground and the soil stays damp for days. The beans are on a mound, but that soil stays damp.
There are also peppers in the planters and ground with the tomatoes. They don't have the spotted leaves.
I learned that there are many, many possible causes.
In case the cause in a fungal or bacterial infection, do you think Neem Oil will help. (We'd like to avoid chemicals.) Or will it harm the plants?
Thanks!
Paul
