Sow indoors from march on in trays with good sowing soil.  Transplant     the seedlings from april on (avoid frosts). Clip the  seedlings to 8    cm  and plant them about 6 cm deep. Keep moist and weed  free.
 
Sow outdoors from june (avoid frosts), when the soil is warmed up, in      rows 30-45 cm apart. Thin to 12 cm apart when the seedlings are   about    15 cm tall. Keep moist and weed free.
 
Harvest when the tops are brown and dry by pulling up the bulbs.      Onions need fertile, moist soil enriched with compost. Don't sow or      plant onions on a plot where onions have grown in the preceding year.      These onions can be stored in a dry, cool and dark place. Some people  say that growing plants with a strong odour should be grown in the  proximity of onions to disturb the onionfly. Think plants like  chamomile, carrots and summer savory.
