The Red Grano Onion is a short day, regular red onion that produces uniform bulbs that store well. In about 100 days this variety is all Heirloom, open pollinated, and Non-GMO. The Red Grano is one of the easiest red onions to grow. We recommend that you plant at least 6 inches apart to avoid crowding. Onion seeds can take up to two weeks to germinate, so keep your seed beds moist! Happy growing!!!
