This crop performs well when night and day temperatures are between 16 and 18 °C and 20 and 25 °C respectively.
Sweet peppers grow best in sandy, loamy soils with good drainage and a pH between 6 and 6.8. Large quantities of Nitrogen are required by the plant early in the growing season, with supplemental applications after the fruit setting stage. This crop requires plenty of potassium and calcium. Potassium is consumed at a rate approx. 50% higher than Nitrogen. Calcium deficiency inevitably produces blossom-end rot in the fruit.
