All About Onions

Soil Type: Loamy 
Soil pH: Neutral 
Sun/Shade: Full Sun 


  • Plant onion seeds 4-6 weeks before the last frost. 
  • Plant onions in well-drained nitrogen-rich soil. 
  • Till in compost & manure before planting. 
  • Sow seeds in rows ½-1 inch deep and 4-6 inches apart. 
  • Make sure temperatures don’t go below 20° F. 


  • Plant Food onions every couple of weeks to get larger bulbs. 
  • Onions should only receive 1 inch of water per week (including precipitation). 
  • If you want your onions sweet, water them more often. 
  • Add a layer of mulch to help retain moisture and to prevent weed growth. 
  • If your onion plant develops a flower stalk, cut or pull away the “bolted” onion. Storage for bolted onions is impossible so use the onion as soon as possible. 


  • When the tops of the onions turn yellow, use the back of a rake to bend the tops and loosen the soil to start the drying process. After 2-3 days, or the next sunny day, turn them up and let them cure on dry ground in the sun. 
  • When the tops turn brown, pull away the onions. 


  • If you are going to store your onions, let them dry for 3-4 weeks first. 
  • Store onions in temperatures between 40-50° F.

“The onion and its satin wrappings is among the most beautiful of vegetables and is the only one that represents the essence of things. It can be said to have a soul.” 
- Charles Dudley Warner, ‘My Summer in a Garden’ (1871)
