Feed your plants with miracle grow powder special blend for tomato. Dilute in water in a gallon jug or, I put it in the container that attaches to the hose and water evenly speeds it for each plant. I do it twice a month. Whenever the plants leaves look wilted or less green. The food helps them revive again and grow much faster. The harvest will be plentiful and plant will grow rapidly just don't over feed or water you will cause splitting of tomatoes and excess nat problem. hope this helps
