OK, I know not to comlpetely bare root a juniper like my procumbens nana when repotting. So when I did move it from its long term home in a nursery pot I only removed the nursery mix (mostly bark and compost) from about 1/2 of the roots. When I next repot it I am wondering how to go about removing the other half of the nursery mix withut disturbing the half growing in a very well drained bonsai mix. Won’t all the pumice and stalite just fall out of the roots as I remove the nursery mix or should I expect so many fine roots in the mix that this is not a concern? I’d also like to cut back on the root ball at the same time as it is now in a fairly large pot dictated by the original 3 gal nursery pot. I did whack off about 1/3 of the roots a couple years ago but more needs to go. Would it be too much injury to remove another 1/3 of the roots while replacing the nursery mix with bonsai mix?
