Yes, any seeds that sprout during a germination test can be sown. Depending on the time of year and what they are, the sprouted seeds could be transplanted into pots (indoors or outdoors) or planted directly outside (if conditions are suitable). When planting, use clean hands or tweezers and handle the sprouts as minimally and carefully as possible. If the seed coat is still intact, handle that, not the roots or shoots. When planting, it’s best to bury everything just below the soil (or potting mix) surface. The plant will figure out which way is up.
