Tomatoes are packed with vitamins and nutrients. The plants are a favorite among home gardeners. Most home gardeners will tell you that store-bought tomatoes cannot compare to the depth of flavor of a home-grown tomato. Although most consider tomatoes to be a spring and summer crop, it is possible to grow tomatoes year-round. Tomatoes don't require a certain time of year to grow, they require certain conditions.
Fill a container with potting soil and plant the tomato seedling in the center. Water the plant immediately. Thereafter, water only when the top inch of soil feels dry to the touch.
Position the plant indoors near a source of light. Ideally, place your plant near a window with western or southern exposure. If your space is dimly lit, suspend grow lights over the container with chains.
Fertilize the tomato plant with liquid fertilizer once a month. Mix with water according to the directions on the fertilizer's package.
Provide warmth, if necessary. Tomatoes grow at temperatures as low as 55 degrees F. In the north, or in home basements, the temperatures may fall below that. If this is the case, use heating mats made specifically for plants.
Provide at least 10 hours of bright, unfiltered light each day. If you are using grow lights, adjust them so that they hang no further than 6 inches above the top of the seedlings. Placing the light too high above the plants causes them to try to reach for the light, which creates weak stems.
