Greetings, here's a survivor of the early freeze event I mentioned in my intro post, turns out rmjs seem to be pretty tough, for this one the huge box probably helped too.

This one came out of the rocks with an absurdly large rootball, just very slightly smaller than the size of the rootmass in the pics below. I could barely pick it up but somehow managed to stagger down cliffsides, through dense brush and down talus slopes to my car.

The rootball was an incredibly dense mixture of decayed organic matter and fibrous roots, pretty much like a solid block of felt. I tried to loosen it up before potting but any attempts to open the rootball up resulted in tearing of all the surrounding roots. It was impossible to decipher where the roots began or ended or even which direction lead back to the tree. The only option to loosen the rootball would have been sawing into it somewhere but you never know if you might hit a major root and sever the line to who knows how many feeder roots.

So leaving it as a giant felt block I planted it into a large box with about an inch or room either side. The growing medium was mostly smallish particle size granite grit. I used a smaller than usual particle size because I was a bit worried about too frequent waterings leading to root death within the large original soil mass. The outer new soil was watered well about twice a week in warm weather and the whole thing watered every 2 weeks or so. It's been in the box for 3 or 4 growing seasons now.

The tree did ok with this treatment, not the vigour of a well established RMJ in good free draining soil but a bit more vigour than it would typically have in the mountains.
Here's a look at what I found when I pulled the sides of the box off, I'll continue the story from here.IMG_1579.jpgIMG_1591.jpg
 
Here's a couple close-ups of the roots in the new medium. Interesting to see the strong healthy roots growing into the void within the soil where I didn't get the new soil into contact with the old. Seeing this I tend to think that a larger particle size would have been fine and probably better.IMG_1581.jpgIMG_1582.jpg
 
Here's another interesting result, the root growth into my main organic component. Broken up chunks of partially buried decaying conifer logs. This stuff is known to treeplanters and foresters as "red-rot". Treeplanters love it because it's soft and easy to plant in, foresters seem to constantly change their minds about whether or not it is good to plant in.
Anyways, nowadays I break it up and sift it, I used to just fire handfuls of the chunks into the mix.

Here's a pic of the sifted stuff, a pic of the rmj roots growing into it and a picIMG_1597.jpgIMG_1593.jpgIMG_1529.jpg of some dogwood roots from another re-potting. The dogwood root pic shows the red-rot briken in half and full of fine roots. So far I have to say roots seem to love the stuff, everytime I re-pot I wind up with chunks of red-rot dangling on the end of roots like corks on one of those aussie flyscaring hats.

I'm going to have to finish the story later, sorry, my computer is painfully slow, as are my huntnpeck typing skills, it's a beautiful day outside and my dog needs a walkin'.

It went well, though, should be a success...

Hey, I just found a pic of this tree in it's box from the end of last season, kind of looks sadly neglected doesn't it? At least now I will be able to move it around, you'll see some brown foliage in places on the pics. Mostly they are in areas shaded by the fence and other branches, now I'll be able to expose more of it to sun.

Back to the re-pot...

Combing out the new roots that grew into the granite grit was quite easy. Once I got into the original root ball it was still very tight and rigid but softer than it initially was. Raking the roots out would still result in the breakage of pretty much every root combed. What I found to be most effective was to push the old soil through the root ball with a sharpened bamboo stick, hrs of push and wiggle later I had loosened the exterior to the point that I could finally start to rake some roots outward and make sense of what was what. At that point I got a bit rougher and got my fingers inside and began crumbling and shaking soil out, finally making progress and getting rid of some old soil. On the one side of the tree the root mass was already pretty close to the trunk so I did not disturb that side much. The other side I got much deeper, despite efforts to be gentle plenty of broken root ends on that side but lots of soil removed. I feel the tree will recover well this year and start growing strongly soon. Next repot it may be possible to get this tree into a real bonsai sized pot, maybe, hopefully..

Here it is in it's new home and in the latest soil mix, pumice,granite,scoria,perlite, a touch of red-rot chunks and charcol all sifted from 1/2-1/16'' and a dash of decaying forest floor litter layer.IMG_1643.jpgIMG_1642.jpgIMG_1599.jpg
This is the first time I've been able to get my hands on some pumice, the new mix looks and smells great, I think the tree are going to love it.

It's been a good couple days playing with trees, I made a right good mess in my yard thats for sure! I got through a bunch of other trees, some pulled out of a growbed and into pots for the first time, hopefully I'll find some time to post a few more trees.

Good luck growing everyone,

Hey MP! Good to see you posting here!

Looks like a nice tree. Glad it pulled through. Looking forward to seeing more of your stuff here. Or even better, email me some pics :D
 
Thanks Cory, the chickens are great, really easy to care for, my favorite is when they find a beetle too big to swallow easily and run around the yard chasing each other, chicken football, really funny to watch. they do like to scratch up the garden and grow beds though.
 
The tree looks exceptionally healthy this spring, nice to see. Styling wise it's challenging material I'm not planning to style this year unless the image pops for me, mulling over a few options for sure though.

Here are a few others that made the first step from boxes towards more appropriate sized containers. I was happy to see excellent healthy root systems on all of them.

Love this picture! Chickens and bonsai!! I like your RMJ, too! It will be a nice one. Welcome to the "Nut House" as its affectionately called.

So is that one officially named corned beef?
 
I've been thinking about having chickens in my yard, but the stray cats would eat them.
 
How long after collecting do you start fertilizing? I collected a J. monosperma last month that has nowhere near the root mass that your RMJ has.
