🍅 How to extract tomato seeds: Scoop seeds from ripe tomatoes, ferment in water for 2-3 days, rinse, and dry on a paper towel. Store in a cool, dry place. Seeds remain viable for 3-5 years.
💡 Pro tip: Indeterminate tomatoes need 24-36″ spacing, determinate types 18-24″. Expect 10-20 lbs of fruit per plant in a good season. Plant 2-3 seeds per cell and thin to the strongest.
