The Q&A Archives: Leaves Falling off Pepper Plants

Question: The bottom leaves and the blossoms are falling off our bell pepper and banana pepper plants. What is the problem?

Answer: If your pepper plants are not receiving enough water, they will drop leaves and produce few peppers. Another cause of blossom drop is high temperatures -- above 90 degrees F. You could mulch the soil around your plants to conserve moisture and cool the roots, and then be sure to water deeply when the top inch of soil is dry to the touch. Plants grow better with a deep watering every 3 or 4 days rather than a sprinkling of water every day.

Peppers also need magnesium for good fruit production, which you can provide by spraying the blossoms with Epsom salts. Mix 1 teaspoon Epsom salts in 1 quart of water and spray a couple of times at 2 week intervals.
