What to Do When Your Pepper Leaves Turn YellowWhat to Do When Your Pepper Leaves Turn Yellow

Even seasoned gardeners occasionally run into problems with their pepper plants. When the leaves turn yellow, it usually signals a problem with the plant and it’s important to identify the cause so you can address it quickly. The most common issues are water stress and nutrient deficiencies, but disease and pest infestations can also cause the leaves to turn yellow.

Water Stress

The first thing to check when the yellow pepper leaves is to make sure the planting location is not too hot or too cold. Peppers are naturally tropical and like warm, dry weather, but if they experience extreme temperature changes they will be stressed and their leaves may begin to turn yellow and wilt.

Other nutrients that may be deficient include magnesium and calcium, so you can try adding these to the soil by using a mineral soil tester or a soil testing kit from your local gardening store. You can also add some humus to the soil, such as composted chicken manure or rabbit manure, or use a granular fertilizer that is high in these nutrients.
