HI Boon.
Would that be true for red pine also?

I got another question. If I repot in Jan how long should I wait to decandel? Or what should come first, decandeling or repotting?

For which tree(s)?  Refined?  In trainng?  Seedling?  For what purpose?

Decandling and other such techniques are typically reserved for more mature trees. It's also typically done at very specific times of the year. There's a lot of information already on the forum. It might be worth looking through the pages (and pages) of information already posted here.

i have a JBP in training, i want to repot it to get all the soil out and and put it in akadama because its in soil with sand and bark and i want that gone...but i want to decandel it when the time is right to get back budding more and get shorter needles...it has a lot of back bud growing on it right now....but i think i should just repot it...i dont know..i think i'll just repot it and decandel it next year...

How about 5-needle pines (JWP)? I was told March-April for the Bay Area.

Repot into good soil first (do not bare-root), then fertilise to get the growth really strong before decandling.

If the tree is new to you, probably decandle the next year. Often when we acquire a new tree it is very under fertilised and weak. Only decandle when the tree is strong.

why not bare root? should i bare root only half the root ball?
here's a pic of the tree that i want to repot....i want to put it into a bigger pot and then maybe in the ground in like 2-3 years from now..

You'll probably kill it if you bareroot it. I'd look at barerooting 1/3 of the rootball each year.

Can only say for UK based weather conditions. I repot both Black and White Pines nearer to late Spring which here is around mid to late April; sometimes I go into May. It is difficult to be overly precise on dates et al, as weather can be quite different from year to year, hence the tree is the best guide to precisely when.

Bareroot as has been mentioned would not ever be a consideration for me. Indeed normally I would only prune hard a maximum of 50% of the rootball. The following repot say in two years (talking large stock now) would see the balance of pruning completed, then I'd leave for between 4 & 6 years; again, I am talking about larger stock.

Whilst mycorrhizal fungus is of great benefit to Pines; indeed one could say they will not survive without its presence, you should not throw caution to the wind just because you have it. Yes, it generally signifies a very healthy tree, but this can also work against you by simply having too much within the rootball area. You should check water is getting through and more still, draining correctly. I have inspected many pines over the years with water penetration difficulties and in almost every instance it has been down to an over abundance of this hugely beneficial fungi.

I've waffled, sorry.

Final word then; keep it on the dry side prior to repotting. It will make the task so much easier, and you should find (if correct medium has been used) the old soil will simply fall away after careful dibbing of the root ball complex. This aids the process and prevents unnecessary root loss. I said about percentages of removal. There are exceptions and that is when you find much dark brown almost black roots. These need to be removed to create space for new feeder systems to generate.

I know I reveal my ignorance on this point, but would you mind explaining a little more why you would expect that?

And would you say the same about Scots pine (P. sylvestris?)
