The tomato has been with us humans for thousands of years. This is
perhaps partly because it sustained us very faithfully throughout these
years.

The seeds are quite hardy. It is known that they do best when first
dried. They do not need to be vernalized (i.e., exposed to Winter
conditions before growing), although, as a new gardener, you should
familiarize yourself with the fact that other seeds depend on this.

In getting your seeds to sprout, they will need heat. Somewhere around
75/95 degrees F (let us say 30 degrees C) would be optimal. Do not fear!
These seeds will do very well until next year, and when the time arises,
if you give them these temperatures, they will faithfully begin to furnish
the next generation.

Later we can discuss fertilizers.
