To transplant onion seedlings, water the nursery bed well, gently uproot pencil thick size seedlings with soil intact, trim the tops , and plant them in prepared seed beds, burying only the roots of the onion seedlings to avoid deep planting which hinders bulb formation, then water consistently. Water daily or twice a day depending on evaporation, for the first weeks. Apply nitrogen based fertilizer for 2-3 weeks after transplanting and every few weeks until neck appears. Weed carefully by hand 7-14 days post transplanting.
