Just as a matter of curiosity, (I've never successfully grafted anything in my life) How would you go about propagating an Apricot tree found growing in the wild? I mean for rootstock, not fruit.

The reason I ask is that there is a naturalized Apricot growing in the undeveloped city park near me. No run off, no fertilizer, nothing but rainfall that it receives in the worst ten-twelve years of drought our recorded history. Its simply growing in the previousy uncultivated rangeland. Its gone from a seedingy to a healthy-looking six-footer in that time. Obviously stooling woud be out of the question. Could you get that really toxic cloning gel and do it with a cutting? What?
