Posts Tagged ‘Onion from Seed’

I just wanted to say that with only a few years under my belt growing Onions, I can personally claim that Onion from seed (Preferrably from a good Heritage seed supplier) does far better than from sets (mini bulbs pre-grown to a small easy-to-handle size).

Yes, onion from seed are (or at least Seem to be) quite finniky / delicate to handle but Don’t let this put you off! The results are far better in my opinion.

Onion seed vs sets

Heritage Onion from Seed (LEFT) vs Commerically Available Onion Sets (RIGHT)

Take note that in the above photo, I grew Two types of Onion set and both were just as bad in terms of bulb swell and overall failure (Red Karmen and Stuttgart)

Why do (did) I still grow Onion from sets if I seem to have such better results from seed? Because this was my first proper season from start on my ‘new’ allotment and I came across a good deal in Lidl I think it was, for a bag of around 100 bulbs it was something ridiculous like $0.69p. So I decided to do a comparison test since I now have a much larger space to play around in.

Pros and Cons for both parties (Pro’s highlighted in Bold):

  • SETS:
    Can be contaminated with fungal growth or spores from storage or the production facility,
  • Most (probably 50-80% in my experience) didn’t get much larger than the little bulb that went in! (Don’t throw them away, make pickles!),
  • Need netting in the first weeks to prevent birds etc. from pulling them out before they establish,
  • Will need constant watering until they establish,
  • Are convenient if a Gardener is overwelmed with small seedlings on all available windowsills etc,
  • Save on plastic pots and compost,
  • SEEDS:
  • Are quite delicate when small,
  • Need one pot and compost per plant (or group of plants if following Multi Sowing),
  • In one year I had all of my onion seed attract aphid really early (February / March if I remember correctly?), however, that was well before I found out how to control them,
  • Have a much more well developed root system and romp away shortly after planting,
  • Swell up quicker too,
  • Far more disease resistance when compared,
  • Better options to choose from (such as storage length, taste, size etc.),
  • Establish quicker so need less tending,
  • Do not need netting,
  • Higher bulb-swell success rate as per observation (larger bulbs),
