Week 17 is April 26 - May 2 in 2010
Tomatoes not need to grow on a trellis. They’re perfectly happy to crawl over the surface of the soil. That’s how many commercial growers do it. However, when allowed to sprawl depending on the variety, one tomato plant may take up as much as 12 to 15 ft.² of growing space. When grown on a trellis, it will take up only 2 to 3 ft.² of garden real estate. I prefer to trellis my tomatoes. Tomatoes that are grown off the ground are clean and avoid problems such as soil rot and bug and slug damage. The leaves of vertically grown plants get more exposure to the sun, and improved air circulation around a vertical crop reduces the chances of disease. Also vertically grown crops dry off faster after a heavy dew or rain, and this further reduces disease problems.
