Answer: Container grown vegetables are known for needing extra nutrients and extra water because of their artificial growing conditions. The plants need to be kept in vigorous growth to keep blooming. Since male flowers are produced first it is especially important to keep the nutrients and water in good supply for when the female blossoms appear, especially as the season gets hotter and the plants grow larger. Your plants may have become too crowded or the soil may simply have become depleted; you may find some additional tips about potting soils and maintenance in the book "Container Gardening for Dummies" by Bill Marken, ISBN 0-7645-5057-8.
