David,
You harvest your plants along the way to make space for some of them to make larger bulbs, yes? And use the harvested ones as green onions?
I side dressed my onions with some Ammonium Sulfate yesterday. They're growing in my Earthboxes. Looking nice. I planted fewer per box (20/per) than last year (30/per), and closer in from the edge of the box.
When to plant onion seeds?
GG,
That's the theory, but I just start with my onion plants 4"-6" apart. That leaves them room to grow without thinning. I don't get the really huge onions, but do get plenty that are bigger than a baseball. For me, that is ideal size for cooking. Typically I use one onion per recipe. I plant the dry sets to grow green onions. They produce more quickly, since they have the bulb for reserves and initial growth energy.
Ok, D.
They just look closer in your pic on the left!
tx- 8" depth is more than plenty.
8" depth???! I planted my plants only about 1.5" deep last season, and got really nice sized onions. Only problem was they were too close and I wasn't thinning out soon enough. When I did, they continued to grow to nice size.
at the top of the forum she asked if her 7-8" soil would be deep enough, not her planting depth. i planted some white onions that will get about 4-5" diameter. on the pack it said to plant 1" apart. i planted mine 5" apart.
Whew!
