The Q&A Archives: suffering tomato plants

Question: I've planted several varieties of vegetables, in pots on my patio. I have three tomato plants that are all located in different areas of the patio. All three have browning leaves and produced some tomatoes but all new flowers have died. All of my other vegetable plants are doing fine. What in the world could be thr problem? The leaves don't look eaten by anything. But the stalks do have some dark spots on them.

Answer: Sheryl,

The browning foliage on your tomatoes is most likely due to a fungal or bacterial disease. The blooms dying without setting fruit is most likely due to the hot temperatures. You can purchase tomato disease sprays but I would not do so now since during summer most tomatoes don't set well anyway. The small fruited varieties set okay in the heat but the larger fruited types don't. If it were my plant I would either just wait for fall and then start to spray it to protect the foliage for some new fruit set when the weather starts to cool or go ahead and spray now to keep it healthy to avoid it going downhill too much in the meantime.

Thanks for the question. Please stop in again soon!
