I have yellow, white and purple onion bulbs. How far apart in the rows do I plant them, how deep should I plant them and how far a part should the rows be?
Plant each onion set 1 - 1 1/2 inches deep and 1 - 2 inches apart, in rows about 15 - 18 inches apart. Make sure the roots are down and the pointy end is up. You can harvest scallions when they are pencil-sized, and thin your onions at the same time. Those onions you want to mature should ultimately be 3 - 4 inches apart, to allow for bulb formation. Because onions are shallow rooted, weed carefully, or mulch after the plants have emerged, to keep down weeds.
