growing brussel sprouts

Question

All of the plants have what appears to be a black fungus. What do you think is the problem and how can I correct it? Or do I have to take them all out?

Answer 1

Sounds like you have either black spot or sooty mold. YOu don't need to remove the plants, but the fungus may affect the quality of the produce.
