Root Over Rock Chinese Elm Update

Happy New Years folks. Here’s the last project for the year. It’s a root over rock chinese elm I grown from seed. I thought I’d share more of it’s history before I describe the work I’ve done to it.

The tree began as a doner seedling from a mature elm tree in my neighbors yard. It grew freely for 1-2 years before I decided to dig it out. I gave it an additional season to grow in a pot and doubled the size.

Identically aged elm but never dug out

It spend the entire growing season in the ground with the roots firmly braced with seram wrap and external anchors. Here is the tree from roughly 1 year ago:

Neglected to take progression shots, but here is the tree prior to wrapping the roots

I dug it out today, slightly early but mind you chinese elms in Southern California leaf out in late January to early February. For most trees it would be ill advised to do heavy root work and pruning in early winter but given the vigor of elms as well as the mild socal temps I can get away with it. Given it grew freely in the ground it has more than enough stored sugars to recover.

Leaders cut and some roots removed

I took off all the seram wrap and checked all the roots. I did some reduction and cut off the 4 foot leaders from the trunk. Everything was reanchored with wires tying down any major root to the rock.

The intended front of the tree. The large root in the front may be split later but for now I’m leaving it alone as it’s one of the main anchor roots

Union is not too bad but rock can still be pulled off roots

Grew like gangbusters on the other side. Some reduction done here to expose more of the rock

I organized the roots evening the spread and cut back to where I could get some division or ramification. The nebari will need further refinement over the years but I need to wait until it’s firmly attached to the rock before additional work.

Repotted, with the roots slightly exposed. Every year I will plant the tree a bit higher showing more of the nebari and rock

My intention with this planting is to have exposed roots hanging off the left side of the stone. Next year this should be achievable and will make for a interesting tree with character. I’ll begin primary branch development this season as well. Hope you enjoy the update and have a great 2018!
