I’m always trying to find easier ways to do things on the farm, and this method of using mustard as a bio-fumigant in our soil (and as a way to add organic matter) has been one of the best.

All I do is seed mustard in mid August, wait until they flower, mow them down with a flail mower, immediately water (we use overhead wobblers from @neversinkfarmtools), and then cover with a tarp. There’s a lot of cool research from @cornelluniversity about this.

We’ll leave the house shut up like this until it’s time to prep for planting in spring.

I wonder if this would work in zone 3 in our shorter season!…

Love this! Does it work in the field too or just a tunnel/greenhouse situation?

Nice! Mustard seed is on my list! I’ve only tried buckwheat. So they flower and then mow in spring?

are you rotating tunnels each season, or planting other crops before/after?

This is something I have been interested in! I will check out the Cornell research!
