Answer: Oranges and tangerines are usually propagated from budding or grafting, and sometimes from cuttings. I was not able to find specific information about starting these from seed, but you can always try! Start by placing the seed in a soilless seed-starting mix, moisten well, and place in a plastic bag to retain humidity. Then wait! Seeds from hybrids are sometimes sterile, and if they do grow usually do not reproduce "true to type"; that is, they do not mirror either of their parents but may harken back to an ancester--possibly one that is bitter and undesirable! If you truly want a quality orange or tangerine tree, you'd be better off purchasing a plant.
