Question: Can I save seeds from my vegetables for next year?
Answer: If they were hybrid plants, no, you cannot. They won’t “come true” from the seeds they produce. That means you’ll get some other random collection of seedlings, almost always inferior to the one you had grown. Buy fresh seed. Inbred varieties, by comparison, can be saved. Porter tomatoes are the best example. You can cut the fruit open, spread out the seed to dry for several days, then store it cool until the following year’s planting time rolls around. They do reproduce true to the original plants.
