Turn left over green onion stalks into a whole bed of scallions. All you have to do is plant the unused scallions in the soil, and allow at least one stalk to thicken and flower. The flower will eventually form seeds, which you will use to plant a new bed of green onions. You can continue to take cuttings from the other scallions for cooking.
You will know when the seeds are ready to be harvested when the stem of the plant turns yellow, and you may even see some of the black seeds ready to spill out.
Cut the stem under the seed head during a dry time of the day. To save the seeds all you need to do is shake the black seeds into a bag or shake the seeds directly into your garden bed. The seeds should sprout within a week as long as you provide adequate water.
