I was told two years ago that it is a good idea to knock over the top of an onion plant to encourage it to grow bigger in the middle. That worked good two years ago, but it didn't work at all last year so I'm thinking it was just coincidence.

Is there anything I need to be doing to the stem of an onion to encourage them to bulk up?

I think that was pure coincidence. Have you tried using a low level of nitrogen (N) and a high phosphorus (P) number? The only other thing of is the use of good soil with good water drainage. Do you use any type of manure (chicken, etc) when planting?
