|This is not the readers tomato plant. These|
are some leaf spots on tomato that were
never identified but probably diseased. Make
sure your leaf scorch is not a disease problem.
A. I dont know how you prepared your soil for the container but that is important. So make sure it is a good quality soil if you prepare it yourself or buy it in bags. Tomato production tapers off when temperatures consistently stay above 95F. Tomatoes and many other vegetables do not set very well under high temperatures. As temperatures drop, they will begin to set again.Vegetables that set fruit will need at least 6 hours of strong sunlight every day.
Morning sun is preferable to afternoon sun because usually afternoon sun also means a hotter microclimate. Direct sun on containers can fry a soil, particularly if the container is small, single-layered, dry when it gets the direct sunlight and dark colored.
I would double pot containers (one container inside another) to help reduce direct sunlight on the growing container. Put the plants in direct sunlight in the morning hours, make sure you use a good soil each time you plant and modify it with good compost.
