In Iowa farmers generally plant the green pepper plants in the field from May onwards. The planting can even be undertaken in June. Before the bell peppers are planted cereal rye windbreakers are sown in the fall to protect the young plants from wind. Generally farmers in Iowa plant as many as ten to fourteen thousand plants per acre. It is believed that the Lafayette variety is the best variety to be planted. It is to be noted that bell peppers grown in Iowa suffer from the high temperatures, during both the night and during the day, mid way through the growing season. The day time highs can be corrected by a sprinkler irrigation system, but this can damage the crop during the night.
