If you are planning to create a garden using seeds

If you are planning to create a garden using seeds, you should sterilize them before you plant. Sterilizing the seeds will kill disease organisms as well as weed seeds. You should begin the sterilization process after you have collected the seeds from the vegetable, herb or flower you are interested in growing. Although it takes time and effort to sterilize your seeds, doing so is very rewarding, as you will likely end up with quality crop that you might not have otherwise.
