The Art and Science of Bonsai

Bonsai, the Japanese art of growing miniature trees in small containers, is also a science. The term bonsai aptly describes what it is – “bon” means tray or low-sided pot and “sai” means plantings. I gave some examples of bonsai (and a related Chinese form called penjing) in a previous post. Ironically, while bonsai is emblematically Japanese, the art was originally developed in China and only adopted later by the land of the rising sun. Here’s a quick reminder of one kind of bonsai tree:

The art of bonsai cultivation is passed down from generation to generation. And since managing a single tree may take many decades or even hundreds of years, the tree itself passes through many generations. The oldest one in the US National Arboretum remains vibrant today at 389 years old. So how does one cultivate a bonsai tree? That is where the science comes in.

Since these plantings come from regular trees, they must begin as cuttings or seedlings. Regular trimming, pruning, and manipulation is necessary to keep the trees small and create the desired shape. While the type of tree chosen influences the potential shape, there are different styles ranging from formal or informal upright, slant, or cascade, as well as more advanced styles such as root over rock, forest, raft, and windswept. Examples are shown in my previous post. To get these shapes there is quite a bit of physical manipulation.

Bands like the one above help pull together larger boughs, while heavy copper wire is used to direct future growth into twists and turns.

More wires and struts help in the shaping.

More advanced techniques include grafting of new plant material into existing trunks (to create side growth), defoliation, trimming, and the brutish-sounding trunk chopping. Considering the amount of manipulation needed to create these masterpieces, one has to reassure themselves that plants, unlike animals, don’t experience pain.

Ah, the tea bags. Many of the bonsai and penjing displays contain several tea bags. They are filled with natural fertilizer. Each time the tree is hand-watered the bags become soaked and leach out nutrients. Still, because the trays are so shallow and the trees are living organisms, regular repotting of the minimal soil must occur.

The incredible amount of attention needed to train and maintain bonsai trees requires patience, effort, and ingenuity from the grower. But to those of us who see and appreciate the art, these works deliver a sense of serenity that pervades the very essence of our souls.

    • Thanks, Ru. I enjoyed digging into the science, just as much as I enjoyed the artistry of the bonsai themselves. Truly beautiful.

  1. I never considered that there wasn’t a bonzai tree seed that people would just plant and grow these things. I’ve often found them to be beautiful, in a way, and was aware that some major work went into the cultivation and management of them, but to the extent of that effort I was not.

    • Many people make growing a single tree a lifetime dedication, and then train their children to carry on after they have died. Quite impressive.
