June 2015: I first had the pleasure of seeing this European Larch in early June in the garden of my student Alex. He had acquired it from the collection of an experienced enthusiast who had kept it alive in a pot for many years.

I instantly fell in love with the old, cracked bark, the exposed roots and the movement in the first branch, but felt that the tree would greatly benefit from being reduced in height. At this point in time, the tree was over 24"/60cm tall and I felt that a reduction by 50% would create a far more powerful tree.

A few days later and Alex brought his Larch to my garden so we could begin the process of styling it. Rather than simply chopping and removing the top and right hand sections of the tree, we decided to try to airlayer them to create new trees in their own right.

Alex cut a wide ring-bark around each section to be rooted prior to wrapping with sphagnum moss and plastic to create the airlayers. (The process of airlayering is described in detail elsewhere on this website). Our hope was that new roots would appear before the end of the growing season and we would be able to separate the new trees.

I then wired, shaped and positioned the heavy remaining lower branch of the 'parent' tree so that Alex could begin to develop the final design while the airlayers rooted.

September 2015: 3 months later, Alex brought his tree back to my garden for us to complete the work. One of the airlayers had produced plenty of fleshy red-tipped white roots and was ready to be separated and planted into its own pot.

We sawed through the base of the airlayer to remove it from the parent tree and then planted it into its own pot. After some discussion we then decided to separate the second airlayer; on inspection we found that the although the tree had no roots, it had calloused well.

Eager to finish styling the parent tree, we planted the second tree into its own pot in the hope that such drastic action would prompt the callous into rooting immediately. From experience I have learned that is a common occurence, albeit risky.

Our next problem was to dress the remaining chops/wounds at the top of the parent tree. We had the option of either removing the stumps entirely or turning them in deadwood features.
