Harvesting and saving seeds from your own garden crop is not only economical, it is a great way to pass down "heirloom" seeds to your friends and family for their gardens. Peppers of all varieties are a summer garden favorite, and when it comes to collecting and drying pepper seeds, the process couldn't be easier. There are a few steps you should follow, however, to ensure that your seeds will be viable and produce a good crop when you decide to plant them.
Choose a healthy pepper from your garden harvest. The pepper must be fully mature and ripe, and the skin should be starting to wrinkle.
Cut open the pepper, and scoop out the seeds.
Remove any pulp or debris from the seeds.
Spread the seeds out in a single layer on a window screen that is laying down flat. For better airflow, place a 1 inch block under each side of the window screen. The screen should be in a dry and well-ventilated area and left alone for two to three days.
Place the dried seeds in a paper envelope, and then place the envelope in a sealed jar or another moisture proof container.
Store the jar in the refrigerator until you need to use your seeds.
