Some tips for planting tomatoes include planting seeds indoors 6 to 8 weeks before the last spring frost date, choosing a site outdoors when the time comes that gets plenty of sunlight and to fertilize plants 2 weeks before they are picked for the first time, according to the Farmer's Almanac. It is also recommended that tomatoes be planted in a place where they have plenty of room for air to move between the plants, reports Rodale's Organic Life.
Another important tip and consideration is to rotate the tomato bed over time so that the chance of disease due to the soil is much lower. Tomatoes should also be watered each week when the summer sun is out. It is best to water the tomatoes by concentrating on watering deep into the soil instead of by watering the leaves, notes Rodale's Organic Life.
