Q.my basil has a disease
So my basil has some black spotting/coloring on it. I am picking off leaves that do not have the color on it, and picking off the black area on individual leaves as well. Can I still eat the basil? Or if it has a disease, should I not?
This is most likely Bacterial Leaf Spot.
I would remove the effected leaves and if you can improve the air circulation around the plants that should help.
Avoid watering from above. I would not consume the effected leaves.
