Watering the onion cutting helps it adapt to its new environment and grow roots faster.
Give your onion enough water that the soil is damp to the touch, but not soaking wet.
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
Onions thrive in soil with a high nitrogen content.
