Prepping Containers for Onions in September

Noob question.
I'm in South Florida, Zone 10 A.
I grow (or try to grow) everything in containers, buckets and or pots.

I love Onions. The kids hate them but that only means there are less people I have to share with.
Anywho, I want to plant me some onions. I was thinking of planting them randomly in pots with other plants because they are low while other plants grow upwards. Sort of a duplex arrangement.
I was also thinking of making one dedicated container just for the onions.

Any tips for a noob?
I have got the basics. I plant to plant seeds in a tray and then transplant when they look a little stronger.
I'm just not sure about the soil, watering and spacing. Also what plants they might be compatible with to share a container.
If it helps, I plan to plant the yellow spanish onions.

Sorry no one has responded to your post. I have only grown onions from seed one time and they did ok. As far as what to plant them with, I don't know. Don't know what the most compatible other plants would be.

I do plant onion sets from the bag every year, and can say that I plant them around other stuff that does grow higher and they do well. But, of course, I harvest them as green onions early. I'll plant them in a circle too, around tomatoes, grape vines etc. Don't know if this helps with your question or not! Good luck!

If you are growing green onions, they do well year round in pots. If you want round onions, red onions, garlic, shallot and other bulbs, you have to get the right kind. You want the southern varieties and you have to wait a couple or three months to plant them. If you plant them at the wrong time or the wrong kind you will end up with bulbs that were smaller than you started with.
Texas granex does well and soft neck garlic for me. I get the garlic from Costco from Christopher Ranch. It is the right kind and they are not treated. I keep them in the refrigerator drawer for at least 6 weeks, sometimes more. Dust them with a fungicide before planting. Texas granex seed is the same as Maui sweet onion. I do warn you that like the Vidalia and the Maui onion, the soil and climate will make a big difference in their sweetness.
Dixondale farms has a tutorial and a list of varieties for the south
