Monster Multi-trunk Boxwood
This is a boxwood is a single plant and sizable shrub. The digging was pretty easy, but cramped with other garden plants and the concrete slab. Before digging I lied down and took the below image. There are many trunks emanating from one central trunk. The branches on the left side of the image could be developed.
Here is the boxwood, wider then my car. It was pretty heavy despite brushing off most of the soil. I dragged it from the backyard and planned to thin out some obvious poor branches, to lighten the load.
Here it is thinned out a bit. I had to use a strap to hold the swinging trunk closed.
Below is the tree before I began work.
Based on my knowledge of boxwood and what I found in recent research. My plan was to keep some lower branches and eliminate any crossing and dead branches. In doing this, I can open it up and allow light to penetrate the interior of the branches, and hope for back-budding on the older branches. It ended up looking really leggy, but that was essential. Keeping the green growth on the ends of branches ensures the survival of each branch.
The plan is to see how the tree responds and then cut it back more drastically once new growth forms on the interior.
Another thing about box is that it takes a really long time to grow out branches, so I will be slow in deciding which to keep because they can not be regrown easily.
Below is the pile of branches cut off, with another the same size cut before I loaded it to transport it home.
Some scale with a 16oz PBR.
Below, I began reducing the root ball and bare-rooting the boxwood. Boxwood typically has a nice shallow root mass and this it the case here. There are nice fine roots.
A potted it up in a big yellow recycling bin, the biggest thing I had on hand. It was filled about one third of the way with soil. Below is the boxwood with the bonsai bench.
Below the movement of several trunks can be seen. Boxwood can have boring straight growth so I plan on utilizing some of these wavy branches which move from center to right in the image below.
Here are two images that show the girth of the trunk(and a bit of damaged bark from the long day).
In this image you can see the green tips and the leggy growth. I am wishful that it will back but well and fill out the interior. By next spring perhaps I can consider cutting it back some. Repot planned for 2020.
RIP:
This Tree did not make it!! the leaves quickly dried out despite being in partial shade and being watered well.
Lessons: either don't bear root and leave it in its soil surrounded by substrate.
Or instead of trying to keep the live veins going by keeping foliage, perhaps I should have cut in back hard and let buds regenerate when the tree could sustain them in its own time
