I have some questions for you........

You said your tomato flowers are dying as well as the lower leaves...
Do you have any tomatoes that have started to come into fruit??
Like to be able to compare them too???
And what are your growing conditions,
what the fertilizers, etc.

Verticillium and fusarium wilts are soilborne diseases that cause yellowing of the leaves, wilting and premature death of plants. These diseases persist in gardens where susceptible plants are grown. Once they build up, the only practical control is the use of resistant (VF) varieties.

Early blight is characterized by dead brown spots that usually start on the lower leaves and spread up the plant. Upon close inspection, you can see concentric rings within the spots. Although early blight is most severe on the leaves, it sometimes occurs on the stems and can cause severe defoliation. Certain varieties (Roma and Supersonic) are more tolerant of early blight than others.

You know I was thinking of all those at first when she was discribing the tomatoes, but I've never heard of the flowers (blooms) being affected by those??????

Sweetpeas,
Can you tell us if you have any mulch down under the tomatoes, so the dirt doesn't fly back up onto the tomato plant at watering time or when it's raining????
