Repotting a Shimpaku - need advise
« on: March 20, 2012, 10:56 PM »

    I am planning to repot a Shimpaku from nursery soil to bonsai soil to improve drainage.

    What is the safest way to do this? Can I only repot half of the roots and leave the other half alone like Boon's suggests for pines? Can somebody give more details about this,

    Thank you

you can. if in a nursery can, make sure you know where the root crown is (clean the top soil down to the nebari by removing the top soil) and cut off 1/3 to 1/2 of the root ball  (aka well below the nebari!)with a saw. clean out 1/2 of the root ball like Boon shows, then repot with a rapidly draining moderately coarse mix. Good luck, protect from freezing (I know, but we may be having arctic weather and snow in April....).
