Fertilizing your onion plant regularly helps it grow large, healthy bulbs. Spray the onion plant at least twice a month with a nitrogen-rich fertilizer until the onion plant's bulb starts to poke from the soil. When the bulb starts poking out of the soil, stop fertilizing the onion until you harvest it. your onion when it forms flowers. When your onion starts to grow flowers, it's ready to harvest.
