Not for this year. Next year mulch under the plants to keep any splashing of water/mud back up on the plant. Some tomato varieties are also more disease resistant than others.Oops, got busy out on the deck. Tomatoes are sick. Yellow leaves with black spots. Happens almost every year. Ideas?
For this year, trim off the yellow leaves and spray with a mix of 3% hydrogen peroxide and water at 1 part peroxide to 9 parts water ratio, then respray after it rains. When you water water underneath so it doesn't get the plant itself wet.Oops, got busy out on the deck. Tomatoes are sick. Yellow leaves with black spots. Happens almost every year. Ideas?
In a pot, already mulched since beginning of season. OK, will try all of this today.

Next year mulch like Expat said and prune the lower foliage off. Look up a video on pruning tomatoes to get an idea. The disease is in the soil and it gets splashed up on the plant when it rains and when overhead watering.
is it in the ground or a pot?
