Try to be careful about the fertilizers you use for onions. Onions tend to be more pungent when grown on soils with a high sulfur content.

Onions may need lots of moisture at the beginning, but less when the bulbs are approaching full size. When the tops begin to fall over naturally, it's time to pull the onions up.
