heres an english hawthorn i picked up at bonsai environment last january. i gave it a haircut to get rid of the branches i didnt want and left it to grow. now im going to concentrate on building the branches. however i had a question; the nebari is not that fantastic, there are a few skinny young roots at the front, and some larger roots at the back that would have been ok, but - as i said - they're at the the back. i've heard that hawthorns dont air-layer well. is this correct? and if it is, it would rule out using a wire tourniquet or tile to create a new set of nebari,, wouldnt it? so i guess my question is: what do i do with the roots to make a better root-base?
heres the tree straight after it's haircut,, the shoots are now about 30cms long

and heres the roots
