What is ag lockI'd use 1/2" thinwall electrical conduit for staking. ( Also known as E.M.T. - electrical metallic tubing ). It comes in 10 ft. lengths. I would keep the whole length and drive in about 2 ft. of it and let the rest to give upward support. Soft, sandy ground may require more distance driven onto the ground. While the tree is still young, I'd drive the stake about 6" away from the trunk and use Ag-Lock to fasten the tree to the stake.

You got that right. The deer around here are relentless. We literally can't grow any flowers in the yard bc they get eaten every night. One even tore my cage off one night and pruned my enterprise pretty good.I'd leave that one as it's a pretty good crotch angle after the staking. I'd prune off the two lower branches in March. At that height they'll get eaten off as soon as they stick through the cage.
