Based on observations from the 2020 growing season, Kristine wanted to test the efficacy of intercropping cauliflower with onions in their market garden.

In a Nutshell

  • Kristine found that the green stem variety performed better than the white stem and Romanesco varieties.
  • Kristine found no significant difference in yields or plant health between cauliflower planted alone (control) and cauliflower intercropped with onions (treatment) in either the spring or fall plantings.
