Maintain consistent moisture—keep the soil or growing medium slightly damp but not soggy. Place the pot in a sunny spot receiving 6–8 hours of light daily. Avoid extreme temperature fluctuations, as onions thrive in moderate warmth. Fertilize lightly with an organic fertilizer every few weeks to boost growth without overfeeding, ensuring your onions develop strong roots and vibrant bulbs.

Gently remove the onions, brush off excess dirt, and let them cure in a dry, ventilated area for a week.
