Dig a hole that is approximately 6 to 7 inches deep near the pepper plant.
Grab a handful of soil. If the soil feels damp, don't water the plant. If the soil is dry and crumbles through your fingers, give the pepper plant a healthy drink of water that saturates the root ball and soil to this 6- to 7-inch mark.
Continue to monitor the plant and check the soil saturation levels on a weekly basis. If the soil on top of the pepper plant remains moist because of heavy rainfalls, avoid watering the plant. During times of light rainfall or drought, dig the hole and water the plant with room-temperature water once a week to the 6- to 7-inch mark. Water your plant to this mark also if the leaves are beginning to wilt.
Cover the soil surrounding your pepper plants with a layer of mulch. The mulch will trap moisture in the soil and around the root ball where it is needed.
