Germinating Locust Seed
About half of the honey locust seed did not respond to the hot water soaking. I then tried a couple types of hand file, and nail clipper but finally had success with a bench grinder wheel.
Just touch the seed carefully to the grinding stone or belt sander until a small patch of top layer has been removed, then soak in water until they are fully swelled.
Two seeds on the right hand side are half swollen, need more soaking time.
