Onions have been hard for us but this year we just freaking nailed it. Primarily the change was that we paid attention to them (and had newly opened fertile ground to work with).
Using a Planet Junior (thank you Jason from Joe’s Garden for all your incredible support and insight on those machines) to weed the onions was a success.
Also, they got enough water, which makes a huge difference.
We also got a shade cloth to hang over a greenhouse to keep the onions from baking as they cure.
