Insert a 4 foot garden stake into the soil at a depth of 6 to 8 inches. Place it 3 to 4 inches to the side of the tomato seedling.
Clamp the end of a piece of artist's flexible curve to the top of the stake. Flexible curve is a piece of thick wire encased in plastic. It will bend to any shape and will hold the shape.
Twist the flexible curve into a spiral that twists around the length of the stake. The loops should be at least 2 feet in diameter to make enough room for the tomato plant. Leave 6 to 8 inches between each loop.
Loop the last spiral around the outside of the tomato seedling. Insert a tent stake into the ground next to the last spiral, to secure it to the soil.
