The trick I think is knowing when to do that for the micro-climate in which you find yourself.

I read somewhere that Japanese researchers found active roots and mycorrhizae under the snow surrounding Japanese White pines. Seems that even if the top is dormant there is still some activity going on through the winter below ground level but probably at a much reduced rate.

Very useful discussion, thanks everyone who participated.
I have one thing to add: with the growth rate varying on our pines, depending on a lot of factors - not just the season - it is difficult to know how much a tree has absorbed of past fertilisations and how much is still in the soil. Over-fertilising is more detrimental than under-fertilising. So winter is the ideal time not only for a plant to rest, but for the soil as well. I give Seasol, that is all.

:wave: Stronger than normal Spring growth - results of feeding continually throughout autumn AND winter.
Years previously, I had never even considered to maintain Winter feeding at all.
The suggestions by some in this thread :worship: , and now the results achieved, have persuaded me to change my routine.

That pine certainly is looking very strong, KCAR! Agree the iron underneath is a fabulous idea.

The tree looks verdant to say the least! Very healthy. Daft me thought the Reo under the pot was some kind of artistic impression - then I realised its function to hold wired branches . Very clever. [THUMBS UP SIGN]

I guess the Q to be 'is it safe to .......'
I believe it is. I certainly don't miss candle pruning any of my older pines whether they have been repotted or not. Needs to be done every year or you'll lose control. Still a bit too early to cut candles here but I know others who go early and then deal with the larger shoots in other ways.
I pluck needles in autumn to help equalise vigour but if you have not done it I think it should be OK to do now - just not as long to have any effect on the new shoots. If you do have long older growth with lots of healthy needles you can still prune further back into last year's needles instead of just taking the candles off.
No point in plucking new needles when you're just going to cut off the entire needle in a few weeks.
