Till the new garden area using a rake or rototiller. Dig the tines of the rake or rototiller into the soil until the soil is loose, working to a depth of 8 to 10 inches.
Remove all rocks and weeds from the soil and place in a garbage bag.
Perform a soil test, available at garden centers, to test pH. Take samples from four different areas of the garden, mix together and test.
Add lime to the soil if pH is too low or sulfur if the pH is too high. Add lime or sulfur until the desired pH level is met.
Empty bags of compost or manure into a wheelbarrow.
Shovel a 3-inch layer of one of these amendments on top of the soil.
Re-till the area to incorporate the soil amendments, working in rows until the garden area is completely tilled.
Drag a rake back and forth over the soil to smooth the soil level.
Water the garden area until it appears well saturated.
Dig a hole large enough to accommodate the roots and base of the tomato plant.
Remove, with a shovel, the soil around the outside perimeter of the tomato plant. Work in a circle 2 inches away from the plant and shoveling to a depth of 8 inches or until the plant starts to release from the soil.
Remove the plant from the soil by its base when it starts to separate from the soil.
Place the plant, roots first, into the new hole. Pack the soil lightly around the base of the plant, making sure to completely bury the root ball.
Water the soil around the plant until it is completely saturated. Water the plant whenever the soil is warm and dry to the touch.
