Tomato seeds are a warm weather crop best if started indoors about 6-8 weeks prior to final spring frost. Plant 2-3 seeds 1/4" deep per cell in fertile, humusy, and well-drained soil with a pH of 6.0-6.8. Seeds germinate in 5-14 days, transplant best starts to 1 per pot or 18-36" apart in the garden. Ideal in container gardening. Before sowing, know whether the seed is determinate or indeterminate, as each will exhibit different habits.
Determinate varieties mature to a predetermined size, producing its fruit all at once with only a minor need for staking. Indeterminate varieties grow indefinitely through the season, producing non-stop fruit while requiring heavy support. San Marzano Short Vine tomato seeds are a determinate tomato crop.

Harvesting San Marzano Short Vine Tomatoes
Smaller varieties such as the cherry are ready to harvest at about 80 days from sowing while larger varieties like the beefsteak may require a few extra weeks. Although vine-ripened fruit is always preferred, tomatoes can just as easily be harvested early and ripen indoors by being stored in a paper bag or box along with a banana for its ethylene gas. Ripest tomatoes may be pulled from the vine by hand, while more firm ones should be clipped with shears.
