I initially thought I liked rooting with DE, but it seemed to suck the moisture away from the roots. And when trying to up pot the DE would adhere to and break the roots. Contrary to common belief, fungus gnats will set up shop in DE as well.
I now keep it pretty simple. I wrap in buddy tape, use an organic mix plus perlite, root outside, and have good success. A friend of mine who used to run a commercial pecan orchard and has rooted 1000s of trees over the years told me about his own rooting method…which is not earth shattering, but works for him. He inverts a plastic cup so that water disperses at the bottom and the cutting is less likely to rot. His method makes up potting simple because the cup lid is easily removed and the tree slides right out. As a bonus, the cups are less likely to fall over in the wind or if a clumsy person or pet bumps them.
