Just a quick post today tracking a task I do on the semi regular to develop the junipers that have deadwood and shari features.

Above: a small shimpaku Juniper I have been developing for a number of years.

Above is yet another of my trees in desperate need of a wire. While I didn’t wire it today, iI did do a little thinning of the foliage in preparation for summer growth and a future styling. The main task i completed however, was the widening of the shari’s on the tree.

If you’re interested in seeing the tree 10 years ago, HERE’S it’s first post.

I do this task every couple of years to slowly reduce the sizes of the live veins which speeds up trunk thickening (or more like widening) and develops the shari’s texture.

The technique it’s self is fairly straight forward and involves removing a couple of mm of bark along the edges of the shari. It is a fairly safe process as you have to be pretty unlucky for the branches above to be reliant on the narrow strip of bark but it does pay to make sure that you are not removing all of the bark from directly below branches.

You can see the freshly exposed shari in the images above.

By reducing the size of the live vein you direct the same amount of sap (to supply the foliage above) through a thinner section of bark and as a result it tends to thicken in this area much more quickly compared to a larger area of bark supporting a similar amount of foliage. If you then have live veins on each side of the trunk they will grow outwards and appear to thicken the trunk much more quickly (if only in one side to side dimension.)

The other benefit of doing this technique over time is that you get a great texture on the shari areas. As you expose these new areas of shari, you are exposing younger heart wood and as a result you get lines appearing between the younger and older area of shari. You can see this quite clearly in the images above where there is a year or two age difference between each line. You can end up with an almost finger print like pattern on the shari with no need for carving and its a fairly effortless way to achieve a nice texture.
