If there are strange spots developing on the leaves of your plants, you might have bacterial leaf spots. And, it’s a particularly nasty problem because there is no cure for this plant disease. There are ways to slow the spread, but once your plant has it, there’s no way to save it from its fate.
Bacterial leaf spot causes spots, often water-soaked, that spread across the plants’ foliage. Spots can be yellow, brown, or black. Infestations start small, appearing on just the foliage, fruit, or stems at first. The bacteria get in at an opening in the plant. It then spreads rapidly throughout the rest of the plant and then to other plants in your garden, killing numerous plants.
Prevention is the best course of action when it comes to this garden disease. Bacterial leaf spot is tough to treat, but there are plenty of preventative measures that stop the disease from making your garden a new home.
