The leaves of my tumbling tomato plants are turning yellow and curling up. They are in the garden in a hanging basket. There are loads of flowers on them but they don't seem to be setting tomatoes yet. Please advise me. Thank you.
Tomato Plants Turning Yellow

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. SInce it's in a hanging basket, I would bet it's a watering issue. Container plants, especially hanging ones, need daily watering, even twice a day when temps rise above 85 F.
