It’s good to think in terms of zones when discussing energy balancing. Especially with cascade bonsai, which present unique challenges. The illustrations in this post are all from our Masters’ Series Pine book (Growing and Styling Japanese Black and White Pines).
Think zones
All trees have strong, medium and weak zones. Because most trees are apically dominant (most of the energy flows up to the apex), the top is usually the strongest zone. Exceptions are low growing and spreading shrubs and some small trees.
Energy balancing is critical with cascades
It can be difficult to maintain the all important lower zone of a cascade bonsai. In fact, without timely application of balancing techniques, it’s not unusual to see the lower tips, and even whole lower branches of a cascade die.
Sacrifice branches
Notice the sacrifice branch growing at the lowest tip in the illustration above. Sacrifice branches are a powerful tool when it comes to energy balancing. Stay posted for more on sacrifice branches soon.
Candle pruning (pinching) is essential for energy balancing on pines.
Pines and non-pines
Though the illustrations in this post are specific to pines, the basic rules apply to virtually all bonsai. However, pinching techniques vary depending upon the variety of bonsai you are working on. We’ll post techniques for other types of trees in future posts. Meanwhile, you can use your imagination and perhaps do some research on your own.
Needle thinning is another important energy balancing technique. With other types of trees you might look at thinning leaves (by snipping the leaf stems) or pinching off buds.
More grate help, the illustrations are nice to. thanks Wayne
