when should I harvest my onion

Question

I don’t remember what I planted. It’s either green onion or onion. It has bolted to 5 feet tall and topped off with a hugh white round flower head. Is it any good to harvest, and if so, does it need to be cured like garlic before being eaten? The green part is thick and 2 inches around. What should I do about harvesting at this late stage? Also, the green never fell over. Is that expected of green onions or regular onions?

Answer 1

When you are ready to eat them. I like mine small, but let some grow bigger.
