Proper soil preparation is essential to the success of your tomato crop. Agricultural Extension Agent John Repair says the first step is to rototill the soil in early spring to eliminate young weeds and improve the texture of the soil. Never till or dig when soil is wet. Once you've prepared the soil, lay down black plastic mulch in the form of landscape fabric. This will reduce weed growth, slow moisture loss and keep the soil warm.
Warmer soil means enhanced tomato growth in early spring and summer.
Plant seedlings started at a nursery, or start your own seeds indoors in late winter. Tomatoes should be planted after the soil has warmed to the touch. Plant several varieties such as 'Big Beef', 'Beefsteak', 'Early Girl', 'Better Boy', 'Sweet One-Hundred' or 'Ace' to ensure a longer harvest. Place the tomato plant in the prepared hole, and fill around the roots with soil. Mark the plant with a tag indicating the variety and date planted, and water through the hole in the mulch, avoiding getting water on the leaves.
