Nice picture, James!
Storage conditions vary and, importantly, the requirements of different vegetables and fruits in storage vary. My basement seems to be really good for keeping onions. Long past when sweet onions are supposed to have reached their "pull date," mine are still in good shape.
Only shallot seed is directly sown in my spring garden. I also have a flat of bunching onions to transplant out ... along with the sweet onions

. I put shallot bulbs back into the ground last fall, along with some garlic sets. This is the first time in about 35 years that I've grown garlic! It's also the first time I have left shallots to overwinter. Usually, those bulbs go in with the first planting of things, in the spring.
When I first tried leeks, I wasn't very optimistic. I associate leeks with the UK. The arid summers here seemed a long way from the weather on the British Isles! Leeks do okay, however

. I started seed for them, the bunching and sweet onions in the greenhouse in early February. You should know that I don't turn any heat on in there until mid-March. Those things went outdoors for a little hardening-off, yesterday.
