Hear, hear! Callery can be put to good use!
I will be going down the road of using self-sown Callery as a rootstock as well. I’ve already dug 4 of them but that taproot broke my digging fork handle. I’ve got some scrap (#12?) rebar and thick wall electrical conduit and am going to weld up a new version of my “pine popper”, much like a 2 tined broadfork. What method have y’all found is best for digging a Callery?
I’ve found that my cutter mattock (fitted with an extra long handle and with the axe side removed from the head) work well for destroying eleagnus, autumn olive, leatherleaf mahonia and Chinese privet, all of which are invading this area.
