Some late spring cleaning

A little late is better than never. Ideally, needle pulling is a late fall to winter activity. On JBP that grow slower (corkers), or are weak (recently repotted, underpotted, constantly candle-cut for ramification and small needles), it is ok to wait longer to pull needles.

The reason why is that green needles contribute to photosynthesis and therefore, the longer they remain on the tree, the stronger that tree can get.

So here are a few examples of early May needle-pulling.

First up is this corkbark JBP, ‘Taihei’, which is a slow-growing tree that I do not decandle. I repotted it last year, and wired it, so I waited until now to pull needles. I will prune, wire and pull more needles this fall.

Next is also a corkbark JBP, ‘Hachi Gen’ on its own roots. It is under potted, and needed to be repotted last year, but i didn’t get to it until this year. I also don’t decandle this one,

The carnage! Probably half of the needles removed, leaving just about 5 pairs on each shoot.

After. Much more even, definitely needs to be detail wired in the fall.

Finally, this JBP has been kept in “show-shape” for four years now, and finally was shown in the USNBE last fall. I repotted it this spring, and just pulled a few old needles to tidy up the undersides of the pads. Our annual Alabama Bonsai Society show resumes next weekend and I thought the tree still looked good enough to show.

Quick update on Corkbark Japanese Black Pine, ‘Taihei’

Since we negotiated terms, this pine has grown better. I don’t decandle it in the summer, I don’t wire every branch, and I don’t repot it often. For it, the tree stays healthy and looks generally decent.

However, I do trim strong shoots, remove dead needles, and pull downward-hanging needles in the fall. Here are a few shots of the minimal work done, per our terms and conditions.

Before any work done on the tree in a year
Old dead needles pulled from the interior
A few downward-facing needles removed, along with a few strong shoots which were trimmed back to a more proximal bud.

And after the grueling 30 minutes of work:

Done for now.

In the spring, I may do a little more wiring in the upper right side of the tree…and I may not.

This tree originally came from Dave DeWire, out in the Seattle area. Dave was a collector of corkbark JBP cultivars and freely shared his knowledge with me when I was obsessed with the different cultivars. Dave died in March 2021, and will be missed in the corkbark JBP corner of the bonsai world. RIP.

Fall Cleanup of a JBP

This pine was candle-pruned in July and the new shoots are opening up. I had a little time to pluck old needles, and remove moss growing on the soil surface. It needs to be trimmed and new shoots will be wired later.

Last year’s long needles are obvious among new, short growth.
Moss growing well….too well
Work complete for now.

Next up, light pruning and a little wire. Since the new needles are still hardening off, I’ll wait just a bit longer on this step.

The pot? Gyouzan, Yuuji.
