I'm goona make this quick. Tree is 5 yrs old in pot... Root pruned it 2-3 months ago and built a sip container for it. This was my first tree ever. Trunk split today... Wtf! Is it dead? Scratch bark.. Still green. Do trees ever survive splits?
Thanks - any advice ? - Mike

It can survive splitting.  You can pull it back together and tape and brace it so it can't split again, or you can remove the less desirable section and keep the best portion of the tree.

Got a picture? Sounds like frost cracking... 

Here's the damage...

I've never had one that big, smaller cracks have healed over OK. 

Yeah it's the real deal bout three inches tall and half inch deep at its deepest point. I've been working on setting up funeral arrangements. Visiting hours will be Friday for those of you that would like to come and say a prayer.

I'd just take a putty knife and try filling it with wood putty.  

I've been doing some research...tree could be too dry, growing too fast. Shocked from too much trimming... I've Read about glue and paint and putty but also read that these methods may or may not work. What works? People on here have talked about splits before but theres not much follow up of tree survival. Just assuming all the trees died?

You don't want to girdle it with a tie. You could try getting a bolt and drilling a hole through the trunk (this will never heal, but if it works the tree will grow around the bolt and will eventually become embedded in the trunk). Get two large washers and put one on either side of the trunk. On the end side of the bolt, attach a washer and tighten until the tree comes back together. Essentially sandwich the trunk between two washers and tighten until it comes back together. You can eventually loosen it a bit or remove it and fill the smaller hole. Wax the exterior so that it doesn't dry out.

That's definitely within my realm of expertise but sounds way too involved and I feel like that could cause even more damage? I'm really not sure what I'm gonna do yet? Prob leaning towards something easy like glue or just do nothing and see what happens...anyone have a survival story of a split trunk?

I assumed you were talking about a split due to a weak crotch causing it to split into 2 sections before you posted your picture.  As far as your problem, I would probably fill the crack with grafting wax and put a couple zip ties until it hopefully heals and then remove the zip ties.

That sounds interesting? Has this worked before for you? Guess I should try something...

I don't think that the wood will fill in naturally since wood grows from the outer layers, not the inner ones. New growth always comes from underneath the bark, rather than the center of the tree. I really think it's advisable that you try to close the split. A wedge graft might work -- it's certainly an interesting idea.You may also want to encourage suckers to grow up from the root base and start over with the trunk? Or maybe air layer the whole tree, by trying to root it right above the split? Use a gallon plastic jug?

I wonder if a wide hose clamp over material to protect the bark would work?

I would try to close the gap as much as possible
Use 4 or 5.Worm Drive Hose Clamps. Once closed use 4 or 5 wood  screws long enough direct on the tree  to hold it together .Once the screws are in place you can take the Worm drive hose clamps off so you can patch the crack with grafting paste. screws will not harm the tree.

Lag screw, carpenters and bone surgeons do it. Compresses the 2 sides together. No chance or girdling

Hi,
Not a common sight. Looks like a split branch pushed into the ground.
The tree could probably heal like that, doing nothing.

Since the crack is at dirt level, I would mound some dirt to let the trunk grow new roots.
I would pull back the tarp/weed barrier that is on the ground to let the tree send suckers.
Later, when roots have grown on the trunk, I would chop the airlayered trunk and let a sucker be the new tree.

Such a crack could be due to standing water or frost. It could be that the tree is dead/ no longer connected to the roots (so airlayering is important) and split. I've seen that on other trees, not on a fig tree.

The trunk is so hard and strong nothing is bringing it together... The clamps just dig into it....

If the scratch test still shows its green could it still be alive? It's not budding... Still dormant. Any test to see if it's alive?
