Autograph Tree Bonsai Demonstration

This demonstration uses an autograph tree (clusia rosea) that is 10 to 15 years old. The tree has an "octopus root" (neagari) style. Work started on Monday, July 15, 2019, and was completed on Saturday, July 20. Photos on this page are by Rick and Andrea Wagner.

Defoliation

There are many reasons for defoliating a bonsai. It can stimulate a second growth for the year if done in the summertime. It allows one to better understand the tree structure while making design decisions. And it can lead to smaller leaves in the future.


I plan to work on the autograph tree in the blue box so I took this "before" photo of it growing in the front yard.


The official "before" shot. It doesn't look like much now, but we'll see. The blue on blue writing around the growing box says "Aloha kekahi
i kekahi
," which means love one another. Literally it says "love the one to the one."


I defoliated the autograph tree so I can see what I'm doing. I removed all the greenery with my bonsai shear. The front of the
tree is more to the right, I think, but that's a decision I will make later when I put it into a bonsai pot.

Crown Reduction

Trees tend to grow more in the top, which is quite understandable. They want to grow big! So I will reduce the crown of this autograph tree to put it more into the proportion of a full grown tree.


I have decided to reduce the crown of the autograph tree. Here I'm making the first major cut.

Potting

The autograph tree has been in its growing box for several years and is ready for a bonsai pot. I have a round Japanese pot that's just right for this tree.


We're going to put that tree (on my left) into this pot.


Preparing the pot to receive the tree. Here I'm cutting screens out of 1/16 inch aluminum window screen.


The large center hole is covered first with a 1/8 inch galvanized iron wire screen, then that is covered with the 1/16 inch aluminum screen.
The three other drainage holes are also covered with 1/16 inch screen. The fine mesh screen keeps the basalt sand from going through the holes.


The screens are covered with wet sand. I use basalt sand that has had the fines washed out of it. The screens are not wired in. It means I will
have to be careful that the screens don't slide off the holes when I put the tree in the pot. Without the sand, the organic material in the
potting soil will clog the screens as it decomposes. So the washed sand maintains drainage and helps keep the bonsai shelves clean.


A half inch layer of potting soil covers the bottom of the pot. In cases where good drainage is essential, a layer of gravel or cinders can be
used. With tropical trees like the autograph tree, this isn't necessary. I'm using Supersoil screened with a half inch screen. It's almost purely
organic material. In cases where more drainage is desired, sand and cinders can be mixed in. I am emphasizing organic material for faster growth.


Removal from the growing box is straightforward. Stand on the box and pull the tree straight up.


Up it comes.


I'm removing soil from the roots by hand into a half inch screen. I will save the used soil for use later because it contains a large amount of
inorganic material (sand and cinders). It can be used to improve drainage of other soil mixes and to fill low spots in the garden.


Now I cut some of the larger peripheral roots using a lopper.


A hand rake is used to remove all the old potting soil.


The roots are washed with water spray from the hose. Here is the result.


I laid the tree on the table to tie some of the aerial roots to the main roots with wire.

It goes right into the pot.


Excess rootage is cut off.


Roots are arranged to fit within the pot.


Potting soil is added to fill the pot.


Soil is added all around and then worked in with fingers.


Another aerial root is tied down.


It's beginning to look like a bonsai in the "octopus root" style.


Getting it wet, wet, wet.


The result next to a bougainvillia I had potted earlier in the day.


The next day, Saturday, July 20, 2019, I added more potting soil on top and finished with a layer of wet basalt sand. I brought it into the
house to photograph with the black backdrop. This is the better front, I think.

I hope you enjoyed this bonsai demonstration. In a few months, when new growth has formed on the branches, I will photograph the bonsai again.

Subsequent Evolution


August 19: one month later the autograph tree sitting in the sun is starting to leaf out.


February 9, 2020: showing the tree to Rainbow Bonsai Club members; it's growing well.
