This maple was brought to me last April for work. It was weak and in examination of the base a full half of the trunk base was dead and rotting away.
I explained to the owner that things would get worse fast with the rotted wood coming away and creating an ugly base. It was obviously also having an impact on the general health of the tree. We opted to layer the tree just above the rotted base at the first point were a full 360 of live tissue could be cut into. We potted it into fine akadama topped off with a thin layer of moss to aid water retention.
Last week the tree came back to me for work and removal of the layer if successful.
Above you can see extension on the tree, even on the lower branches. A good sign.
We removed the pot and found a full 360 of radial roots in great shape. It looked like a hula dancers grass skirt. It had even rooted well above the rotted area where sap full would have been weak.
We worked the roots out to soften the edge and even removed some that had rooted above the callous line into the moss and that would have created an uneven nebari. The stump underneath was whittled away with knob cutters.
You can see on the stump of the old base that a full 180 degrees of the trunk was dead at the base.
We took some time to spread out the roots and potted the tree in a spare pot of mine that allowed more room front to back and a little more depth. I’m fairly confident that this tree will fill this pot in a single year.
The top got a light pruning. The low branches may annoy some but I actually like the image. Better this than a dead tree in a few years. We repotted the original stump out of interest to see the rootmass. The rotted portion just fell away and what roots were there were very poor indeed.
