Q: I grow organic heirloom tomato plants. How do I save the seeds?

A: The “jelly” that surrounds each seed can inhibit germination. Save an unblemished ripe fruit, scoop out the seeds, and cover with water in a glass jar. Leave in a window; in a few days the water will be covered with white mold. Fill with warm water and shake. After an hour, viable seed will sink to the bottom of the jar while mold and debris will rise to the top. Remove the good seed and dry on a paper plate. Save in a cool, dry place until next spring.
