Australian pine air layering
In this post we have a series of photos from Brian to record the separation of an air layering he did done on an Casuarina equisetifolia or Australian pine. the equisetifolia is a species at home from Vietnam all the way through to eastern Australia. It is much used in Asia as a bonsai species and you can find many striking examples on line.
This is the tree before the work started.One lower horizontal branch on the left before a big gap to a group of three branches. Also an unremarkable nebari. The plan was to air layer off the upper part just above that first branch.
Here is the cut with a piece of copper wire wound arond the trunk to prevent the tree bridging the gap. This is a belt and braces move and not essential.
On top of that around the cut where the roots will form some rooting compound has been applied.
After this a 'pot' was put in place to hold potting mix to cover the layer cut.
Brian used what looks like a coke bottle which was left open at the top for easy watering. After just 12 weeks you can see the roots have progressed well from the bottom of the 'pot' where the cut was made. The pot had been wrapped with heavy 'duct tape' while the roots developed.
The tree had one branch on an otherwise long and relatively bare lower trunk. The layering is positioned just above that left hand branch. This will create a shorter tree with better branch density and arrangement.
With what can be seen in the pot there is no need to unwrap before separating, so here it is cut off.
After the cut the base remains, alive and well and ready to be crafted into something unique!
The new tree ready for potting.
Wow what a great mass of roots.
From underneath you can see an excellent strike around the full circumference.
Potted and ready to go. This one will not look back.
