You can save most seeds of plants to re-plant in the spring. Some plants are easier than others. The best candidates are beans, tomatoes, lettuce, and peppers as long as they are standard or heirloom varietes, NOT hybrids. Hybrid seed is often sterile or the new plant is not true to the mixed parents so you don’t know what you’ll get. Plants that are open pollinated by insects or wind aren’t the best candidates for seed-saving. That includes squash which often crosses with other plants in their family. The only way to maintain the original variety is to isolate by large distances which is not always impractical in a home garden. That said, you can try and see how it goes!
