Here are 2 Acer Palmatum trees that I have been developing for a couple of years. They were put into their first bonsai pots today.
The first one was air layered from a larger tree 2 years ago. As you can see in the first picture, it has a strong evenly distributed root system and a nice flared nebari is beginning to emerge. When the air layer was cut, the trunk above the cut was exactly the same thickness as the trunk below the cut. So the flaring at the base has developed in the past two years. I think this is very encouraging for the future development of this tree.
To allow the continued development of the roots, it was planted today into this large shallow oval.
This is the tree that the air layer was taken from.
The next tree was planted in a large garden pot for a while to thicken up the base of the trunk and promote rapid root development. Large sacrifice branches were allowed to grow unchecked.
The roots of the tree had filled this large container by the time the sacrifice branches were cut last autumn.
Today it was removed from the large pot and the roots were trimmed back severely.
The trunk was chopped back and the tree planted into another shallow oval bonsai pot.
Both these trees have some way to go before they become bonsai but it will be interesting to see how they continue to develop in the future. The plan for the coming year is to feed them profusely and re-evaluate their progress at the end of the season.
