Non-traditional bonsai.....Tree of Heaven
I call it my Bonsailanthus ;)
Ailanthus altissima, the Tree of Heaven...which I knew only as "freeway trees" for many years. There's certainly a reason they survive so well in poor soils alongside freeways. Anyhow, turned out a neighbor - two houses up the creek - has a grove of Ailanthus, and he shared cuttings...some for the yard and some for containers.
Started this one in 2005, and the whole project has been a lesson in set-backs. I took it off the deck one afternoon, and the deer ate the top four inches off the one-foot plant. It grew back, but the following two Springs, a hard freeze burned the new growth. Thankfully, in Spring (2008), the last freeze wasn't quite as hard and resulted in branching instead of outright death. But the branching was way up on top of this "stick," a shape for which Ailanthus (around here) is known.
In December (2008), I re-potted the plant. Completely bare-rooted. Removed a secondary trunk that had sprung up (and potted it separately). I pruned most of the root-ball away, too. The soil was old compacted peat-moss, so I had little choice in the matter. Now I know that I work on Ailanthus aggressively when it's dormant. I didn't know how well it would handle the bare-rooting, and no one I asked had answers. I re-potted in a mix of bark, perlite, and pumice.
This Spring (2009), April rolled around and the Ailanthus began to bud. We had no hard freezes in May, which was just about perfect, and all the new growth survived...even some of the smaller branches toward the base of the trunk. Well, I'm sure you know what's comin' next...
I left it on the backsteps for sun one afternoon...even though I should have known better. Yep, the deer got it. They chomped it back to a stick, with only a few half-chewed leaves here and there. Of course, the Ailanthus grew back; and, when it did, I decided to make the next cuts. Now, the plant has re-foliated, and the leaves *are* reduced....compared, that is, to a ground-grown Ailanthus ;)
Next year, I'll prune it even lower. Probably down to the first branch. I'll begin exposing the root-flare (nebari), as well. The bare-rooting this Winter showed me that it doesn't have good roots yet...but some potential.
Here are a few pictures.
