Trimming while seedlings are young is better for root and bulb formation. Cutting off the top green growth forces more of the plant’s energy into the root system and also the forming bulb just above it (onions bulbs are actually the base of the leaf system with roots growing from the base of the bulb).

How long can you leave onions in the ground?

Once they’re down, leave the bulbs in the ground for another 10 days to two weeks to mature fully. It’s not good to leave the onions in the ground for longer than two weeks after the tops die because they become open to organisms that can cause rot in storage, or they might even start growing again.
