Things I wish I would have known: Gardening - mounding up

Have you ever heard the term mounding up? Well, this applies to many of your allums and others, meaning your onions, shallots, garlics, leeks, celery, potatoes, carrots, and others. What mounding up does is it ends up building up your bottom shoots or your root head. When your shoots start thickening (such as onions) simply mound up a little bit more soil around it to build it up and to fool your veggie into thinking that it has to grow some more to reach the air. The root will expand and grow giving you a bigger head when you harvest. If you plant down far enough (seedlings) you should be fine, but if you are planting seeds then you will want to mound up to give you bigger veggies. The same applies to your celeries so that the shoots can be blanched and that you get bigger stalks. This falls into the "Something that could have been brought to my attention yesterday" category since reading all the gardening books it doesn't really tell you this. I figured it out after much trial and error, but I thought others might want to know.
