Onion Sets - Fen Early (Heat Prepared)

  • Catalogue Code 1040-6031
  • Pack Contents: Approx. 75 Onion Sets (250g)
  • Heat-treated to halt the bolt
  • Early-to-harvest
  • F1 generation hybrid for vigorous plants

A superb and handsome chestnut-skin onion producing one of the earliest crops from a spring planting.

We treat these sets with heat for 20 weeks prior to arriving with you. This prevents your onions from bolting (going to seed) so that all the energy in your plants go into making bigger, better-flavoured bulbs.

Fen Early keeps much better than other early types too so you can store them- hang them up in plaits in cool and dry locations like a porch or air-tight garden shed until the end of winter for a supply of flavoursome onions during the cold months.


  • F1 Hybrids are crossed varieties that are exceptionally vigorous and longer lasting

Excellent onions always reliiable and no bolting.




Been growing Fen Early heat prepared onion sets for a number of years and always been very pleased with them. Last year I didn't, and regretted it, as the quality of the onions I chose were nowhere near as good. This year I made sure I bought the Fen Early again and I know I will get a good crop of good-sized onions which will last till the end of the year and beyond as the keeping quality is excellent. Cannot recommend enough the Marshall's Fen Early onion sets.
