Growing onions

[aggiek]

I have been trying to grow yellow onions but they never seem to form bulbs . They grow large and go to seed but the ends are not formed to a bulb . What am Ii doing wrong ?

My initial guess is the soil, but that's simply a guess. I've got a large flower pot of them growing and more in the garden. Actually never heard of them not growing bulbs so I'm at a lose.

Growing Onions in Minnesota Home Gardens - University of Minnesota Extension

Onions (Allium cepa L.) are related to garlic, chives, leeks, and shallots. Storage onions grown in Minnesota generally are long-day types that require 14 or more hours of daylight to form bulbs. Overcast skies and cool temperatures during the growing season will delay bulb formation. Sweet or mild onions are “short day” onions, and although they can be grown in Minnesota, they will generally develop small bulbs. There are also bunching or scallion types grown for their green and white stems that do not form bulbs. Egyptian “walking” onions are perennial, and produce clumps of bulbs. When the clump becomes heavy, it collapses and the bulbs form roots where they land. They are also grown mainly for their edible stems. All onions require full sun for optimal growth.

I've been doing some reading lately because I'm currently growing them from sets. Some of my sets are starting to go to seed, and I've read you need to pull those and use them right away as green onions. Apparently the larger sets typically don't make t he best onions, as they frequently go to seed quicker. The smaller bulbs actually grow into onions better.
