What should be the distance between tomato plants?
The correct tomato plant spacing is dependent upon which variety of tomato is being grown. Generally speaking, the ideal spacing for tomato plants is between 24-36 inches apart. Spacing tomato plants any closer than 24 inches will reduce air circulation around the plants and may result in disease. You also want to enable light to penetrate to the lower leaves of the plants, so proper spacing is crucial. Large vine producing tomatoes should be spaced 36 inches apart and rows should be space about 4-5 feet apart.

Variety does not really matter at all it depends more on how much room you have and your soil fertility. I have planted them as close as one foot apart and as far as three feet apart with similar results. When I plant close, the ground is loaded with compost and aged animal manure (ie: chicken, sheep, cow, horse, etc.) and usually the crop is mulched which helps prevent blossom end rot by insuring a more steady supply of moisture for the plant. This year I planted in raised beds in wire cages approximately one foot apart and the plants are loaded with green tomatoes and Blossoms. For the record I planted 70 plants this year.
Growing vertically will make your tomato plants occupy a smaller area of soil. This is a good idea for those using raised garden beds, smaller garden plots and container gardens. Growing vertically is accomplished with stakes, cages, fences, trellises and teepees. Add stakes, teepees and cages while the plants are still young to avoid damaging the roots. When you plant against a fence or use a garden stake or trellis system, you can train the vines to grow upward. You may loosely tie slender strips of cloth or garden string around the vine and the support to keep vines going upward. Check http://cheapessaywritingservice.us/ for more tips.
Dwarf varieties should be spaced about 12 inches apart in a row. If you plan on staking your plants, space them about 24 inches apart. Set sprawling, indeterminate tomatoes about 36 to 48 inches apart. Plant your seedlings about 1 inch deeper than they are sitting in the nursery container.
