OK You've purchased your tomato plants from your favorite nursery, your planting bed is made, you've worked into the soil your Growth Enhancers which are; Crab Shells; Kelp Meal; Alfalfa Meal & Humate along with some Hi-Cal. Lime for additional Calcium, which tomatoes & peppers need to ward off End-Rot.
Now, very carefully remove all lower leaves, lay half your plant in the soil & bend your plant so that HALF of the stalk is on the bottom of your furrow. NOW place your soil back around the plant and water-in. Keep in mind that ONLY half the plant will be buried with NO LEAVES. ALL THE FUZZY HAIRS ON THE BURIED PORTION OF THE PLANT WILL TURN INTO A LARGER ROOTING SYSTEM.
What does this do? In return for your effort, your plants will produce more fruit.
