Spray the plant with Epsom salts (1 teaspoon dissolved in a spray bottle of warm water (about 4 cups). That gives the pepper plant a boost of magnesium that is required at flowering time to produce fruit. Spray them again 10 days later and in a few weeks, our expert friends report, you will have more peppers than you can eat.
Tomatoes need calcium to achieve their full flavor potential, and calcium is often greatly lacking in our soils. 95% of a dry eggshell is calcium carbonate. When planting your tomato plants crush up (to powder) about 4 or 5 egg shells and put them in the bottom of the hole. Then plant your tomato on top. Theyll provide calcium and prevent blossom end rot.
