This is my method
I assume you already know because you pulled them but always pull before a rain if theybhave been in the ground long enough

If possible I pull and leave in the sun for 3-4 days and them put on a shelf with a fan if possible to dry the stalks

Once the stalls are dry I still try to keep a fan for a month to cure

And yes like burnIt said my onions will last till October and when they start going bad they will sure smell up the garage

Here is some pictures. I pulled all my onions also yesterday and I will only be planting two rows not three like this year

I also started a new fertilizer treatment this year and they are the biggest Inhave ever grown
