Coast live oak is ubiquitous in the canyons and foothills of southern California, providing food (acorns) and habitat for wildlife. In nature oaks often take a “fountain” formation, with main branches emerging upwards from the trunk and then bending downwards at the branch ends. That is the ultimate design goal for this tree, although it isn’t there yet.
The tree was purchased as a pre-bonsai from Kuma Bonsai nursery in San Diego in 2013. New growth was insufficiently pruned in the first years after purchase and it was very spindly until spring in 2016, when it was pruned back hard. I nearly lost it after a hard root-pruning in winter 2018 but it recovered and is currently scheduled for more branch pruning and wiring in spring 2019.
