I like to plant vegetable seeds that I produced myself from previous crops. This is a fun, easy, and inexpensive way to plant your favorite vegetables each year.
Whether you like to grow pumpkins, peppers, tomatoes, or beans, or a variety of vegetables, all you need to do is allow some of them go to seed on the plants at the end of the growing season. In other words, don't pick them for use, but let them become overly ripe.
In late fall before the first frost, take your seed vegetables and remove the seeds. Set them aside in a flat container in an indoor area that gets a lot of sun so they dry out. This process usually takes several weeks.
Once your seeds are dry, put them in air-tight contains or envelopes and put them aside for the next growing season. You can do this year after year with vegetables, fruits, and even flowers so you always have plenty of seeds for your favorite plants when the next growing season rolls around.
