Bruce–squash, melons and cucumber flowers have to be pollinated in order to set fruit. Tomatoes, peppers and eggplant are self-pollinating. You may need to step in and hand-pollinate. Pick a male flower first thing in the morning (a male flower is the one with NO baby fruit at the base. Peel off the petals, then take the flower and dab it gently into the middle of the female flowers (the ones that do have the baby fruit at the base.) That should solve your problem.

Marina–there are a number of diseases that can affect tomato–early blight, late blight, fusarium, verticillium, etc. Unfortunately, there are few to none effective treatments for them. My best advice is to not plant another tomato family member there for three years–no tomatoes, potatoes, peppers or eggplant because the disease can linger in the soil for up to three years. Plant tomato family elsewhere. You can plant cucumbers, squash, green beans, etc. because they are not prone to the same diseases that attack tomato family members.

My tomatoe leaves yellowing and withering? The fruit does not seem to be affected
