Tomatoes love heat, so find a well drained area in full sun (at least 8 hours per day) with organically rich soil (pH 6.0 to 7.0). Tomatoes are heavy feeders and need an appropriate balance of N-P-K (nitrogen-phosphorous-potassium). However, don't overdo the nitrogen for this can lead to vigorous plant growth with lots of foliage, but few tomatoes. On the other hand, yellowing leaves are indicative of too little nitogen. A lack of phosphorous presents itself by foliage which takes on a purplish cast and late flowering; a potassium deficiency delays growth and diminishes yields.
With planting there are pitfalls. Planting too early is the most common mistake. The best method for preventing this is to call your local county extension office and ask for the last expected frost date, and plant one week after that date. There is no need to rush in the garden, the larger, spindly seedlings are quickly caught or outdone by smaller, younger plants. (Also, if you purchase transplants, look for stocky, dark green plants with no yellow flowers). When your planting day arrives, nighttime temperature should stay above 50 degrees F. Dig a bowling ball sized hole for each plant. Add a shovelful of compost and a tablespoonful of epsom salt (calcium) in each hole, and plants seedlings deeply, at least up to the first set of branches, to promote a strong root system.
If you plan to start your own seed instead of purchasing transplants, plant seeds 1/4 inch deep in flats containing cells. Plant two seeds in each cell - filled with potting soil. Keep temperature about 75 degrees F, and seeds will germinate in approximately 1 week. Be sure flats are in full sun. After seedlings have their first leaves, remove the weaker of the two. To promote early fruiting, keep the daytime temperature at 65 degrees F, and nightime at 55 degrees F. Fertilize weekly using a diluted 10-10-10 liquid fertilizer. As the seedlings grow, transplant them into larger and larger containers. Every time you repot, plant seedlings deeper than they were in their previous pot. This encourages new root growth along the stem.
Whether you transplant your own seedlings or store bought transplants your soil should be healthy and rich with organic matter. However, to ensure large yields, side-dress your plants with 2 tablespoonfuls of a slow release granular 10-10-10 fertilizer two weeks after transplanting, after the first flowers appear, when the fruits are golf ball sized, and after the first ripe tomato.
