Question:

What is the proper way to plant onion seeds?

Answer:

Plant onion seeds as soon as the ground can be worked in spring (late March or early April in southern Iowa, early to mid-April in central Iowa, and mid to late April in northern portions of the state).  Plant seeds in rows 12 to 15 inches apart.  Cover the seeds with one-half to three-quarters inch of soil.  When the seedlings are 2 to 4 inches tall, thin the planting.  For large, dry onions, plants should be spaced 2 to 3 inches apart after thinning.  A full season of growth is needed for mature onions.
