Using the right techniques, yes and indeed, that will take many years.
Learn to control your eagerness to work on the tree. First learn how to take care for it and make it thrive.
I'll leave it to grow for now. But i do have a suitable substrate for it but i'll leave repotting it until late fall or winter
Excellent plan (look up the right time for repotting. If I am right, that is early spring for JWP). Meanwhile, I'd like to recommend to get some native, deciduous trees to work on
If this pine was mine, what I might do is:
- Remove the flowers (the red balls under the new needles)
- Reduce the long shoots in the top branches (carefully, and do not fully remove them)
I'm full steam ahead with writing down alot of information here I'm actually finding some knowledge on the internet contradicting
That is true. Trust no one, so also do not trust me
Best source i've found so far is Neil Ryan hes top notch!
Yep. Have you seen the movie about Spring fundamentals? Two hours, but very worthwhile.
I can decandle more towards late summer and decandle the whole tree so he was saying in his lecture!?
You did not learn the difference between white pines (single flush) and other pines, like black pines (multi-flush).
The above is totally wrong. NEVER decandle white pines. Candle pinching is done now, and not in late summer. There will be no second flush, so on JWP you will only pinch candles once. Decandling a JWP may kill it (or not, but it will seriously weaken it).
I thought I posted this article already? Just to be sure. I recommend you read this and understand the difference between which pines can be decandled and which can be pinched but must not be decandled.
