Photo 1: Mustard greens seed pods hanging from fence
If you live in an area that has dry summers, you can dry seed pods from the fence. All you have to do is gather the stalks into a bundle, and then tie them together with twine or strong string. Then hang the bundle from the fence. I just use another string to form a loop, attach it to the bundle, and then hang the loop over a single fence slat. See Photo 1.
