Larger containers with one or more gallon capacity could be used for single plants of tomatoes, peppers or eggplant. Water can be applied by sprinkling or by running water in furrows near the plant rows, in the center between the rows, or through porous or trickle irrigation hose. Whatever method is used, take care not to over water. Too much water displaces oxygen from the soil atmosphere and can cause damage to the roots. Trickle irrigation systems have provided an innovative way to water a garden with a minimum amount of water.
Several manufacturers make trickle irrigation tubing suitable for the home garden for a modest cost.
A system with a tube down each row is ideal and provides the best performance. Since splashing irrigation water can spread plant disease and cause bacteria and fungi, apply the water to the soil surface without wetting the leaves. If sprinkler type irrigation equipment is used, apply the water early enough in the day so the plants can dry thoroughly before night. Some vegetables have a short harvest season. If only one planting is make, these vegetables will be available for a limited time.
