When and How to Grow Onion Sets and Shallots

Onions and shallots are among those crops that quietly earn their keep in the garden. Give them a sunny spot, reasonably good soil, and a little attention now and then, and they'll reward you with a harvest that's hard to beat.

  • Plant onion and shallot sets in a sunny position where excess water can drain away easily
  • shallots prefer rich soil and can be planted in either autumn or early spring, depending on the variety
  • Water during long dry spells, especially while young plants are getting established
  • Keep weeds under control so bulbs have plenty of room and nutrients to grow
  • Lift and dry your crop once the leaves begin to yellow and naturally fall over
