Secrets to growing 'Big Ole' onions?
I am growing Walla Wallas in a SWC. I grew them a season or two ago and they ended up being about the size of a hard ball (baseball) at their biggest. I see people who have harvested the Walla Wallas and other similar onions from SWC and the ground that were like the size of soft balls. So what do I have to do to get them nice and large? BTW...I use 10-10-10 as a fertilizer.
