During August I planted two tomato varieties that have grown into bushes and flowered, but nether has produced fruit. Whats wrong?
By now the cooler but still warmish temperatures should have helped set the fruit on the plant. You can blame the longer than normal hot October weather for the lack of fruit. Tomatoes form fruit when the temperatures are between 55 and 85°F. When the temperatures are too high or too low, most flowers drop off without setting fruit.
