How to Grow Onions

Planting Onions

  • The onion belongs to the family of the garlic and shallot.
  • These bulbs can be grown in almost any soil as long as it is well-drained and fertile.
  • Plant them with the pointy end up about 3 cm (1 in) deep and 15 to 20 cm (6 to 8 in) apart.
  • Water thoroughly after planting.

Growing Onions

  • Weed regularly when plants start growing.
  • Water as needed during active growth periods, but allow the soil to become dry between watering.
  • All-purpose garden fertilizer applied at the beginning and middle of the growing season is effective.
  • Attention! When flowers appear, cut them! Otherwise the plant will divert energy from building up the bulb.

Onions Care

  • When the leaves turn yellow and die, remove the bulbs from the ground.
  • To harvest, carefully lift the bulbs with a spade or a garden fork. Carefully brush off the soil and dry the plants for 2 to 3 weeks in a shaded area with good air circulation.
  • Once the bulbs are dry, you can store them. Remove any dirt and trim off any roots or leaves.

Winterizing Onions

  • Bulbs should be stored in a cool 5 °C (40 °F), dark and dry place.
  • During the winter months you should check your stored bulbs regularly and promptly use any that show signs of sprouting.
