Plant seeds indoors 6-8 weeks before anticipated transplant date; up-pot into 3-4 inch pots when the first set of true leaves appears. Strong light and cooler temperatures (60-70°F) prevent plants from getting leggy.
Plant outdoors when danger of frost is past and night temperatures consistently remain above 55 degrees Fahrenheit. If an unexpected late frost is forecasted, protect young plants with plastic sheeting or other cover. Set plants 2 to 3 feet apart. Tomatoes can be buried up to the top 2 sets of leaves.
Plant tomato plants in well-drained soil and keep them well-watered but not soggy. A thick layer of mulch helps conserve moisture and control weeds; water the plants once a week, but avoid getting the leaves wet. You may want to choose an organic fertilizer formulated specifically for tomatoes.
Indeterminate tomato varieties often perform best when provided with a trellis or support, since this protects them from various pests and diseases in connection with too much soil contact. Put the supports in place before the seedlings develop vines. Pruning the "suckers," or shoots that grow between the main stem and the branches will greatly improve the production and strength of the plant.
