How can I grow tomatoes from seeds obtained from fresh tomatoes?

To grow tomatoes from seeds obtained from fresh tomatoes, first remove the seeds from a ripe tomato and let them dry on a paper towel. Plant the dried seeds in a small pot with potting soil, water regularly, and place in a sunny spot. Once the seedlings have grown, transplant them to a larger container or garden bed. Provide support for the plants as they grow and continue to water and fertilize as needed.
