I am wanting to plant garlic, onions and shallots among my roses and some of my beds. Everything I've read talks about Shallots and Garlic generally being Fall planted, however the Purdue Horticultural PDF for Indiana mentions that they are Spring planted. This results in smaller bulbs though. In my zone, would I be okay planting them in the Fall? Can onions be Fall planted like the garlic and shallots? And last but not least, when should I plant them? September? October? I'm new to growing these babies but I LOVE roasted onions and I use garlic in almost everything and shallots I've always wanted to try.

Thanks for all the help and opinions!
