White Onion Sets

How To Grow

White Onion Sets

Who do I suit? Everyone who has a garden or outdoor area!

 

Planting Sets

  • Sow outdoors until May, somewhere they will get plenty of sunshine (they like heat)

  • Ensure there are no stones, weeds and weed roots in soil before sowing seed

  • Soil needs to have good drainage and be fertile (e.g. add compost to top layer of soil and rake in before planting)

  • The soil should be moist before sowing so water soil day before if dry

  • Place the set (small onion bulb) into the soil so that the tip is just visible above the surface

  • Position the sets approx. 15cm apart from each other

  • Press down on soil to firm soil around the set

  • Keep the soil weed free, ensuring you don’t damage plant in the process

  • Ensure soil remains moist, don’t allow to dry out. 

  • Rake/break up top of soil on a dry day, avoiding damaging the plant. 

  • To encourage growth and deter pests, feed every 6 – 8 weeks with organic fertiliser (e.g. dried milled  seaweed fertiliser, sachets available on sow.ie)

 

Growing Time

  • Approx. 5 months

 

Harvest: 

  • When stems turn yellow and fall over, slightly lift onions in their position to snap the onion’s roots and halt further growth. Leave for 2 weeks (allows onion to expand in the soil).

  • Harvest on sunny day – lift from earth. 

  • Can be eaten directly after harvest but if drying to store, leave exposed to sun/wind for approx. 10 days for drying (or dry indoors if wet outside)  



Tip: Don’t plant onions in the same location every year!
