Candle-cutting comparison

In July, as an experiment, I candle pruned 2 black pines using two different methods; One using the “all at once” and another using the “3-stage” techniques. A look back at that post is here.
As the summer progressed, I photographed the first right branch on each tree to document the relative responses. Far from scientific, but interesting no less. Here are the results.

At 10 days:
All at once pine (the larger of the two):

Interestingly, the more-developed pine is ahead, with needles exposed but the new candles are much smaller and shorter. The larger pine is less-developed, more vigorous, and the new candles are coming back much longer. Considering how closely the two trees were grown this year…from repotting, to soil, site, and care, I believe the single-phase is quite effective, although somehow it seems to be slightly more stressful than leaving some of the new growth while the weak candles catch up.
