Acer campestre/Field Maple Root-Over-Rock Bonsai Photo Series

July 2006: A year later and the difference in the tree is dramatic. Field Maple are very vigorous trees and the sacrifice branch had reached a height of over 10ft in less than a year (the first 3ft is pictured above). What would eventually be the actual bonsai was pruned just before this picture was taken and had been repeatedly pruned throughout the year.

It should be noted exactly how long and thick the sacrifice branch needed to grow to start having any positive effect on the girth of the trunk. Sacrifice branches only increase the girth of the trunk if allowed considerable free growth.

September 2006: For a number of reasons I won't state here, I decided to lift the tree in early Autumn. The tree was dug up with a good sized rootball that was cleaned of ground-soil but not pruned.

With the plastic wrap removed, at long last it was possible to study how well the roots had thickened in just two years.

The tree was potted up into an old terracotta saucer that would be used as a training pot for the next year or two.

The final work to be carried out was to remove the sacrifice branch. I will now spend the next few years building up a new branch structure.

At the time of writing (September 2006), the tree 8.5"/21cm in height above the roots. I am very unlikely to allow it to grow much taller.

The root spread is 10.5"/26cm and the trunk diameter is 3"/7.5cm directly above the nebari/roots.
