To persevere growing tomatoes, despite what nature throws at us, you have to know what you're dealing with and deal with it early. Here are some common tomato disease problems along with what to do about them.

My tomatoe leaves turn yellow then dry up the whole plant looks like its dying. I had the same problem last year. What am I doing wrong?

If they’re just turning yellow and not spotting, it could be too much or too little water or not enough fertilizer. If there are black spots too, it’s one of the many, many fungal diseases that tomatoes get. Try a good organic fungicide or something like neem.

Martin, it’s hard to say, without seeing the leaves. I don’t know that rust affects tomatoes, but many fungus diseases look a lot alike. Once you have a problem, it’s quick to spread.

The only thing to do is to remove the affected leaves and fruits. Then start spraying with either a copper fungicide or some other fungicide recommended for edible plants. Hopefully the new fruits will be fine.

Next year, plant your tomatoes in another area and keep watch, so you can catch any problems early.
