It's been my understanding that the summer repot is ...not....for Sylvestris. Is that true or not? 
Scots pine ....summer repot.....yes or no?

I know a couple people who don't own them who say Yes.
My personal preference is no summer repotting for any pine. Not even mugo.

I feel like a lot of people who talk about “summer repots” are talking about teasing out roots, repositioning the tree and essentially slip potting. This is fine to do anytime!
I personally would not cut roots until traditional repotting time.

I am killing pines. Maybe because of summer repots?
I have seen the pictures by one German artist who does wholesale rootwork on very mature maple bonsai in summer
That famous German artist who repots mature maple bonsai during the summer doesn’t live where you do!
where YOU live, Mike, is marginal for Scots pine, period. Then trying something Unconventional???
Stick with the methods that have been proven by many who have come before you.

know nothing about pines.
what i do know is, if you have to ask, then maybe do nothing. just do it at the time by folk who came before you as Adair has just said!
if you have to ask, you will always get mixed responses. what have you learnt?
that he says yay and she says nay
you might actually learn more with some research.

It could very well be a factor. I have a 50+% failure rate with summer repots.

Someone sent me some pine seedlings a while back which I needed to repot straight away. Those all seem to live, and are actually turning green

I hope I didn't cast a "Pall" over the forum with this question.

I was reponding more to the "people that repot in sumner do not do more than slip-potting".
Local climate will dictate what you can get away with I think.

This thread makes me wonder if there is a resource that shows what work can be done on a particular type of tree at what time and in what zone? If none exists, could we crowd source something like that?

I doubt there will ever be consensus?

I bet you're right, but if we wanted to get really fancy we could stratify the data with confidence rankings.
There are too many “it depends” variables.
Vance has been repotting Mugo in summer in northern Michigan for years. But Mike lives in the Central Valley of California where it’s 110 degrees! Two vastly different climates.

I'm thinking something like a "Mugo Repot Table" with X axis showing the zone and the Y axis as the months. The different intersections would be populated by data from surveys which ask what is your zone and what percentage success do you have with repotting Mugos in each month.
This could be really cool!

Cool! Good to hear that. Mine are black and charred.Someone sent me some pine seedlings a while back which I needed to repot straight away. Those all seem to live, and are actually turning green
Not because I repotted them, but because I think JBP suck.
RJP, Scots, Mugo, Halepensis, Longaeva, Nigra, Banksiana, Ponderosa and Rigida are my new focus.
Did your ponderosa make it?

One could create a program to scour this site and retrieve all the necessary data.
It's already here.
Most of the "it depends" exist too.
The problem with accuracy of new data is folks' lack of information input.
8/10 times a repotted tree dies, it wasn't the repot that killed it.
Folks are too handsy and thoughtless to get around this.
Mike orders all his trees from treesIshouldn'tkeep.com.
Repot when your roots grow! There is no other answer.

Please, you do not seem to be getting the point.
Trees do not "read" human calendars. They respond to their local, immediate micro climate. A "table" with calendar dates is guaranteed to be ABSOLUTELY incorrect except for the immediate location of the author.
Trees respond to temperature, rainfall, daylength and other environmental cues. My spring window of opportunity and my late summer window of opportunity is at least one month different than Adairs window of opportunity for repotting. Because our CLIMATES are DIFFERENT.
In other threads, it has been suggested to contact other bonsai growers in your location to understand when you can do what.
If you are in the Central Valley, you can not take timing of technique ques from a grower in a near Alpine area of Germany. Nor can you follow the calendar of a grower in Michigan. There are a huge number of experienced growers of bonsai in California. Contact @Smoke, or Cathy Shaner, or Peter Tea, tell them you are in the Central Valley and ask when they do repotting, candle pruning and other bonsai tasks that are sensitive to timing.
Stop accepting recommendation on timing from people outside your climate and micro climate. Start learning to create your own individual calendar based on your local climate.

I think of we gathered all the information, we would find out the things that actually cause death, like pruning too hard, not enough winter protection, fert problems, water problems etc, then we could avoid those actions, and Repot whenever.
There has been no rhyme or reason yet at all to repotting times.
It MUST have to do with other surrounding actions.
Yes Everyone falls into their own nook, but our nooks are interchangeable.
