How Far Apart Do You Plant Tomatoes?
Plant tomatoes 24 to 36 inches apart in rows that are spaced 3 to 5 feet apart. Proper plant spacing allows air to freely circulate around tomato plants, which reduces the spread of disease.
Plant Tomatoes Early To Avoid Disease & Insects
Select a sheltered location that receives at least six hours of sun daily. Dig the garden bed in the early spring. Hold the edges of the plastic down with rocks, bricks or boards. Using plastic to warm the soil also kills many weed seeds and fungi, such as Fusarium oxysporum and Verticillium dahliae, which cause fusarium and verticillium wilt. When it reaches a minimum of 55 degrees Fahrenheit, it's time to plant the tomato seedlings. By choosing tomatoes with a short season, the plants are established and producing fruit before pests such as the tomato hornworm hatch in early to mid-summer. Place a handful of compost in the bottom of each hole before planting the seedlings. Trim the plastic so it doesn't touch the tomato's stem. Make a temporary greenhouse by covering the tomato bed with a sheet of clear plastic. Monitor the temperature inside the greenhouse. Watch for pests such as aphids and tomato hornworms. Use a strong stream of water or an application of neem horticultural oil for aphids.
