I planted a bunch of different types of onions the ones at the plot that I planted were from Irish Eyes and I planted those in the future tomato A-frame. I also planted some onion seeds in the herb bed in the sidewalk garden (I am not sure how that will work out - the seeds are kind of old). All my onion starts in the tomato bed came up and I need to do some top dressing and mulching around them.
Here is some great information that I will need to reference later on: How to Grow Bulb Onions from transplants from Irish Eyes.
There are three essential facts to keep in mind about growing bulbing onions. FIRST: the bulb will be no bigger than the top. SECOND: the top completely stops growing when the bulb begins forming. So grow as big a top as you can as fast as you can. THIRD: grow a variety adapted to your zone. Change of day-length is what instructs or triggers the plant to change from growing top to making bulb while the lengths of day and night differ from North to South.
