Although you can easily grow seeds collected from store-bought citrus, the plants they become usually produce less than high-quality fruit. This is because most purchased fruits are hybrids, and seed from hybrids rarely produces plants that have the same qualities as the parent fruit. However, seed-grown citrus can make for attractive foliage plants indoors (be watchful of the thorns, though). If you'd like to grow citrus for fruits, purchase a grafted named variety from a reputable nursery. To grow oranges (or other citrus) from seed, remove the seeds from the fruit and plant them immediately. Use a seed-starting mix or potting soil, placing seeds about an inch deep in the medium. Moisten the mix and move it to a warm location until germination occurs.
