Partial defoliation of a Japanese Maple 

In the early summer, as the first flush is hardening off, it is good to remove one of each pair of leaves, to let more light into the tree. This promotes back-budding, and keeps interior shoots from dying off.

The trunk is beefing up, even after 12 years in a pot, with annual repotting.


Part of the charm of this cultivar, Chishio Improved, is the bright red new growth.  Here is an area that was pruned back a month ago, and new growth is popping out brightly!

2017 Repotting: Japanese Maple, Chishio

Unlike last week’s azalea, this fella is on an annual Repotting cycle.  It’s been in straight akadama for the last few years, and the root system is doing very well in it.


I take my time on this tree, combing out the roots carefully, and then hosing out the soil between; repeating the steps several times until the old soil is washed out.  It allows me to find and eliminate any of the roots that are growing on the bottom and are trying to get strong.  “Planing” the underside of the trunk keeps it spreading out over time.  


Wired back in, and planted deep enough to keep those roots growing.  One day, it’s going to have a very nice, natural nebari.


This tree has been in a bonsai pot for 13 years now, and while it’s tough to see progress year to year, looking back 10 years shows a different story.

The cycle continues: Hawthorn part 3

Picking up where we left off last week, in the summer of 2016:


Fall color was nice:


And in January 2017, it was pruned back, to replace too-heavy branches with thinner ones, prune long shoots back to a couple buds, and reduce whorles to pairs.  

So let’s review.  Nearly 3 years ago, here was the tree:


And here was the advice received from a couple pros:

•Not much taper in upper primary branches. Normal for deciduous trees, but it does catch your eye.

•Trunk goes right, top goes left; straighten trunk in pot, fix branches.

•Grow center branch out to thicken it.

•Shorten left branch; too long and straight.

•Middle branches pointing down, lower branches pointing up; make low branches point down, middle branches point out, high branches point up.

•Open area exposes 3 branches at same height.

•Balance foliage; upper left and lower right are strong, upper right and lower left are thin.

Now, fast-forward to February 2017 and it’s time to prune.  Before:
