Planting Instructions:
  • Start indoors in February to mid-March, and transplant in April.  Scallions can be direct sown every 3 weeks from April to late August.  Sow 3 seeds 6 mm-12 mm (¼-½") deep in each cell of a 72-cell tray.  Transplant spacing for cells should be around 12-15 cm (5-6") apart in rows that are 45-75 cm (18-30") apart.  You can also sow seeds directly into the garden. The soil should be moist before sowing so check the soil the day before sowing and water if  it is dry. We string our rows about 15.2 m (50’) and etch a furrow about 5-12 mm (3/16-1/2") deep. Drop  about 2-4 seeds per 2.5 cm (1”) and cover lightly with soil.  Thin when onions reach about 5 cm (2") in height. Thin them so that they are spaced about 10 cm (4") apart. If planting onion sets, wait until soil can be worked thoroughly in the spring.  A well worked, loose soil is best for planting onion sets.  We string our rows and sow bulbs about 30 cm (4”) apart. If soil is nice and loose, you can just push the onion set into the soil with necks upwards and cover up, leaving just the top of the neck poking out of the soil.
  • Soil Conditions:  Well worked rich, loose well-drained soil. Ideal pH: 6.2-6.8. 
  • Planting Depth:  6 mm-12 mm (¼-½").
  • Germination:  7-12 days.
  • Height at Maturity:   Sweet White Spanish Onions tops grow to about 45 cm (18”).  Spread:  10-15 cm (4-6”)
  • Days to Maturity:   115-130 days for maturity from direct sow.  
  • Watering: 2.5 cm (1") of water a week ensures good growth, whether onions are grown in single or wide rows. The amount of rain that falls during the week affects how much you should water your garden. Keep soil consistently moist until bulbs enlarge and mature. Onion roots are shallow; so a light watering will suffice. 
  • Sun/Shade:  Full Sun    
  • Spacing after Thinning:  12-15 cm (5-6") apart in rows that are 45-75 cm (18-30") apart.

Pull onions at any stage for fresh eating. Harvest young onions to eat as scallions. For full-sized bulbs, don’t pull onions until bulbs are big and tops start to yellow and fall over.  To harvest, pull onions and shake off soil.  Cure onions by placing them in a warm place with lots of air flow.  During curing, roots shrivel and necks dry and tighten. After 7 to 10 days of air curing, cut off onion tops and trim off roots with snipers or scissors.  Carefully rub dry dirt from bulbs, taking extra care not to remove papery outer skins from the bulb.  Temperature: Onions will last the longest in a dark, cool (but not cold), dry storage area. Don't ever store onions in plastic bags. Potatoes and onions should not be stored together.
