There are many reasons to harvest your seeds year after year.
Some gardeners like to pass quality seed down from generation to generation.
Others prefer to save their own seed to save money and still others do it because it can lead to growing plants that produce quite well in their location. Seeds and plants can grow to be resistant to hazards or blights that occur in the environment they are consistently raised in. One method for harvesting seeds, such as vegetables, is to let the fruit ripen on the vine or plant to the point that it is overripe. Once you have picked the fruit or vegetable, mash it gently. Pull out the seeds and soak them in water for 48 hours.
