How To Repair Crack In Tree Trunk
How to prepare a tree with a split trunk from current of air damage
December 15th, 2009
Readers of this blog will know that my favorite tree is my forest pansy redbud, indeed the related posts you'll discover at the bottom of this cannonball volition indicate to the other weblog posts where I have mentioned it. I love this tree because it has spring interest, in the form of the standard pinkish redbud blossoms, but it also has a somewhat unique purple colored leaf that creates overnice interest in the summer besides.
I wanted one of these probably for two years before finding and buying one, and so, dorsum in early October, disaster struck! A wind storm heavily, heavily, damaged the tree. Splitting the trunk in 2 places.
In hindsight going out and looking at the harm, it was leap to happen, the tree had grown and so well that some limbs plainly outweighed the strength of their junction with the body, information technology should have had some preventative pruning done, just I was busy being a new dad.
Some people, when a tree is damaged similar that, would just cutting information technology downwards. If they remember it'll never be perfectly shaped over again, they don't want it. I personally call up a tree that survives damage volition take more than character and exist more interesting, plus, I did say it was my favorite tree, so I decided to repair it.
When faced with this sort of harm you actually have two options, you tin can try to mend the split up, which is possible when it is a fifty/l split up or close to and at that place is still substantial amounts in tact on both sides. Or, if one side is severely weaker, it may not exist able to be saved and and then you'll take to trim it up and get in every bit clean as possible. I had to do both.
The picture higher up is of the upper trunk split, this ane you'll notice is really astringent with no structural integrity left on the right side. Trees practise all of their physiology in the thin green moist layer right below the bawl (xylem, cambium, and phloem layers, sometimes only called cambium) and so if in that location isn't enough bark surface area left to sustain the split branch, it'll die. If you're a few hours or a 24-hour interval afterwards the damage and the leaves are wilting, yous'll know at that place isn't plenty cambium left. You lot might exist able to do some heavy pruning so that the remaining leafage is improve matched to the remaining cambium, but chances are you just need to cutting the limb off.
So, for the damage shown above, the leaves were already wilting and the construction was so patently compromised, so I cut the limb off, as cleanly as I could.
The above picture is of the lower trunk separate. This is the first branching point of the trunk, the first primary scaffold branch carve up off. In this instance though the prognosis was much better, the leaves had not wilted in the least (and I was easily 8-10 hours after the tempest) there was still structure integrity to the branch (it was hanging parrallel to the ground, non drooping all the fashion) and the split was probably forty/60. Then I decided to fix information technology.
The offset thing I did was some astringent pruning to reduce the weight load of the branch. This co-operative had grown significantly during the summertime and actually weighed as well much, I probably took off 70% of information technology's mass. Merely and so I could lift it back into place as much as anything else.
I temporarily tied the branch up with twine, temporarily for a few reasons, namely because if you necktie a tree yous choke it. People run into this all the time with birdhouses. They do not desire to "hurt" the tree so they utilize rope, twine, or wire (the worst) to tie a bird house to a tree. Really, the ameliorate thing to do is just to nail it. A tree tin survive a puncture wound no problem, simply if the tree grows into a rope or wire it'll impede the flow in the cambium layer and choke it.
Subsequently the tree was in place I got out my power drill and bored a hole through the tree at the site of the separate. And then I went down into my basement and looked through my spiral/nut/commodities/boom organizer. In a bin called "toilet parts" I found some big brass bolts, these were perfect. Brass doesn't rust, and being an blend of copper it may accept some antifungal properties. I put a large bolt through the hole and secured it.
I so drilled another hole a few inches to a higher place the carve up and put a longer bolt through there. I fabricated sure the pigsty was slightly smaller than the commodities so I really had to shove and pound it in (thus making certain there would be no gap) and then I used a wrench to tighten basics on both.
My tree was now a cyborg, and the actions I took may seem severe, drilling two holes, but every bit I said, trees can survive puncture holes no problem. There was another flap of torn bawl and I actually brought out my nail gun and put some brad nails into that, more than wounds, just the tree doesn't mind them.
Eventually the tree will grow over those metal rods, incorporating them into it's construction, and being all the more stronger for it, with no adverse harm, because they go through the cambium layer, not around it.
So, weight removed, gash mechanically repaired, now I had to worry about insects and diseases. I had both a can of tree pruning sealer and a can of natural shellac wood sealer. I had just read an article saying shellac was improve than the other stuff and and so used it. Shellac is an all natural waxy resin made past insects and used in everything from wood products, to food, to pills. You probably eat a lilliputian fleck every day, information technology is harmless, merely it seals wood good. Insects and diseases love open wounds and so it was important to seal the tree with something.
That taken intendance of, the last affair I needed to worry about was water. Only like with concrete, water can arrive a crevice, freeze, and then widen and brand the crack worse. Even with the shellac the forcefulness of water expanding as it freezes was a potential risk. What I eventually did, though which is not shown in the picture show, is just put a bead of silicone caulk around the top of the fissure (but not the bottom) preventing whatsoever water from seeping in, but if whatsoever does, still allowing it to seep out. Silicone is a neutral and inert substance and the tree volition probably abound around information technology fine, or, afterward healing has progressed, I can accept information technology out. Some other option would be to wrap the tree in some sort of plastic, simply that can hold in moisture likewise close to the bark and promote rot, I recollect my caulk solution is best.
I'll post an update next year to show how the tree is doing.
Should you repair every tree? No, you lot shouldn't, if there is a safety event where the tree overhangs a structure or is where people often sit, walk, or play, you should e'er err on the side of safety. If the tree limbs are too big for yous to manage to put dorsum into place, y'all may non have to cutting the tree down, but you'll need to remove the limb. But, if your tree is not yet too big to manage (mine was only about 10 feet tall) you tin endeavour to repair it. It doesn't need to be a total loss.
