Thinning procumbens juniper is straightforward. Remove downward-growing shoots, shoots that emerge from branch intersections and shoots that extend beyond the desired pad silhouette. Thin remaining shoots to facilitate wiring.

It had been a while since I last repotted my Western juniper. Although the drainage remained good, I’d been anxious to repot since styling the tree last fall and deciding on a new planting angle.
Wester juniper – August 2012
To maintain the angle indicated during the last styling, I affixed an aluminum wire that marked the front of the tree and the proper planting angle.
Marking the front with wire
After removing the tree, I cleaned and wired the pot before working on the roots.
Wired and ready to go
The pot was made by Michael Hagedorn. I’ve always appreciated the little touches in his pots like the grooves he left for the wires.
Just enough space for the ends of the z-clip
#2 aluminum in the groove – the perpendicular groove at the midpoint allows space for wire-cutters
Signature Crataegus grooves
There were plenty of roots for me to work with.
Lots of roots
After removing the roots from the bottom of the rootball, I found a peculiarly square root.
I pressed a bit from the top and it easily came loose.
Clues from the last repotting
Knocking out the block left a perfectly square gap in the roots.
A perfect spot for new soil
I’d forgotten why I placed the block under the trunk, but after seeing photos from the last repotting in early 2010, it all came back.
Chopstick and block – February 2010
Seeing the photo surprised me as the roots were now solid in all directions.
Plenty of roots to spare
I was able to complete the repotting without the assistance of blocks, however I employed a single chopstick as a short-term brace.
Although I tilted the tree forward and towards the center, the original plan was to have it lean even more toward the front.
Current planted angle
The original plan
I’ll likely tilt the tree farther forward the next time I repot, which, judging by recent history, gives the tree two to three years to grow in peace. By that time the branches will need attention and I can start thinking about when next to show the tree in an exhibit.
This past weekend, Bay Island Bonsai held its 14th annual exhibit at the Lake Merritt Garden Center in Oakland, California. For those of you who attended – thanks for coming! I hope you enjoyed the show. For those who couldn’t make it, I’ll share some of the highlights. We’ll start, today, with some scale junipers.
The Taiwan juniper below has been trained as bonsai for a long time. Its primary feature is its twisting double-trunk. Good movement and interesting deadwood are the most prized characteristics of juniper bonsai – this specimen has both.
Far more complex is the Western juniper below. Its trunk tells the story of the harsh environment in which it grew – well worth a close look.
The Sierra juniper below is off to a great start. All of the branches are in place and in a few years the tree’s fullness will provide a great backdrop for its trunk and deadwood.
This next juniper tree is massive. I’ve watched, over the past 10 years or so, the transformation from Sierra to Shimpaku, and have been surprised at how quickly the tree has grown from a small number of initial grafts. Time will make the tree even more impressive.
Shimpaku grafted on Sierra juniper
The shimpaku below is the product of over 90 grafts! The effort has not gone unnoticed – in 2008 the tree earned the National Bonsai Award at the first National Bonsai Exhibit in Rochester, New York.
Shimpaku grafted on San Jose
Interesting deadwood and impressively dense foliage characterize the Sierra juniper below. The tree makes a good case for how well Sierra foliage can be developed.
A medium-sized Sierra juniper bonsai – something sought after far more often than found.
A small shimpaku fed by a slender lifeline – the foliage is perfectly healthy and full.
