Bonsai Tonight

Pass the sock

Posted in Display by Jonas Dupuich on January 15, 2010

You know a bonsai show is close when someone asks you for the sock during workshop. “The sock,” in Bay Island Bonsai parlance, refers to a sock filled with crushed walnut meat. Walnut oil is great for cleaning bonsai pots and juniper bark for bonsai exhibits. And the effort required to apply it is well worth the time.

Simple how-to: 1) fill sock with walnut meat; 2) tie knot in sock; 3) crush walnut meat with hammer. When the oil seeps through you’re ready to go.

It’s surprising how much oil a few nuts provide. For all but the largest exhibits, just a sock or two can do the trick.

Oiling the trunk

Because junipers frequently present twisting mixes of live and dead wood, it requires care to keep the oil off the deadwood. And while the decision to oil or not oil juniper bark can make for good debate, I have yet to hear a good argument for oiling deadwood.

The results can be just as dramatic for pots. Apply when the surface of the pot is clean and dry.

Ideally, a pot will hold enough oil to deepen the color, but not enough to hold a fingerprint. Rubbing away excess oil after application helps, but the best trick is to apply the oil a week or two ahead of the exhibit. This dulls the shine just enough. And if too much fades, touch up the tree with the sock before heading to the exhibit.
