New research has shown that winter cover cropping with hairy vetch will suppress fusarium.

  Very interesting, I’ll look into this.

    I'm experimenting with it in my garden right now. Definitely had a fusarium issue this year (tomatoes in the same location for 3 years running). I have hairy vetch in now as a cover crop in that bed and will plant tomatoes again next year to see how it goes. This info came from a gardener Youtuber, but it appears backed up from a google search. It appears the experiments were done with watermelons, but I would assume the results would be the same with other crops.
