Save vegetable seeds suspended in gel, such as tomato seeds, by scooping their insides into a container with water. When the seeds sink to the bottom, pour the water off, and drain the seeds.
To save seeds, remove them from ready-to-harvest vegetables, such as peppers and peas, and let them dry on paper towels or newspaper for approximately one week. Store the seeds in a cool, dry place, in resealable plastic bags or mason jars with tight lids. A refrigerator is a good option for storing seeds. Label each plastic bag or jar with the name of the plant and the date.
