Tomato leaf fungus
Once again I am seeing tomato leaves starting to yellow at the bottom of some of my plants. I covered the soil below the plant with newspapers and mulch to prevent splashing. I have drip irrigation. Any good ideas to stop this?
I would not worry about the fact that they are yellow. At this stage of the growing season it is quite in order to remove the bottom leaves of tomato plants to enable the light to ripen the fruit.
