Petunias are annuals so they will die down at the end of the growing season but you can collect seeds to save for sowing next spring. Allow the flowers to remain on the plants. You should see a seedpod developing wherever there was a flower. When the seedpod turns a tannish brown you can snip it off the plant and place it in a paper envelope. Set it on your kitchen counter for a few days to allow the seeds to dry completely then seal the envelope, place it in a plastic bag that you can seal or a glass jar with a lid and store the seeds in a cool, dark place until next spring. Enjoy your garden!
