Harvesting Black Walnuts Posted on October 5, 2020 by glenalmus 0 We harvested all these black walnuts from a friend’s place. Dave put the bucket of walnuts in a large garbage can full of water. He agitated the mix using a dry wall mixing tool to remove the green hulls. I filled an old crock pot with some of the filtered sludge and cooked it down to make black walnut ink. These are all nuts (minus the ones I used to make hermit cookies) after Dave dried them on a sheet all day on the driveway. We gathered a couple more buckets full from this tree next to the dairy barn next door. Our pine tree is a little in the way in this photo. We hear the walnuts hitting the tin roof throughout the fall. There is also a young tree on our property along this fence and we found some nuts under it, too.
