Does the length of my cutting have great importance to the outcome of my pines. I have heard many different theories. Also i am a bit confused about having too many roots on my rooted cuttings. i was reading a shared link here about to dense a root mass that could form a shelf nebari that is competely unrealistic for black pines… How would i , in the early going prevent this. This past year was my first attempt at rooting pines and i have not had years of experience to learn from my work. The photo i posted here is an 11 m0nth old jbp seedling cutting grown in connecticut. I counted 6 radials coming from just one side of the trunk(the side shown) and am terribly proud of this but now I’m learning my desire to produce dense radials might be overkill.
I really think that the issue of too many radial roots is far less prevalent in western bonsai.
I would not worry about too many roots just yet, you’ll be able to cut them off in the future if you decide it is a problem. For now, I’d be proud of the radial roots that you have there.
Good questions Mark. I haven’t isolated a difference that resulted from making a large or small cutting, especially when growing larger trees. It might depend on the development technique, e.g. the technique in Bonsai Today #12 vs. the one mentioned in Bonsai Today #20.
I’m with @scottroxburgh about the roots - there’s time to address the problem, when and if it occurs in the future. The main things to get right at this stage is the arrangement of the roots - spread out vs. all on one side - and the angle of the roots in relation to the trunk.
Years ago I started a number of pines with trunks that grew straight up. That limited my options for styling and led to some awkward repottings where I had to remove more roots than I wanted when I repotted the trees at an angle. Now I start all of my pines growing at an angle.
The seedlings look great, btw - looking forward to seeing them develop!
