Tomato Plant Leaves

Question

I have a big, strong tomato plant with lots of blossoms and young tomatoes on it. I am growing it in an “earthbox.” Suddenly, a few days ago, I discovered some of the leaves are curling up. What would cause that and is it harmful to the plant?

Answer 1

If the leaves are curling and there is little yellowing on the plant, the curling is likely environmental and not an issue. If the plant is yellowing as well, especially accompanied by spotting or wilting, it is likely disease and little to do but pull the plants.
