The art of growing dwarf trees,or “bonsai’’（盆景）as their Japanese creators call them,is increasing in popularity in the United States.Growing bonsai can make a fascinating hobby for anyone who enjoys plants and creating beautiful effects with them. 36
In growing bonsai,first,one must be careful in choosing the type of tree,as the growing conditions are unusual. 37 Varieties of pines with small needles and hardwood trunks are especially suitable.
38 This is necessary because the major growth of bonsai is kept confined（被限制）to the tree’s trunk and leaves,not its root system-a process quite unlike what is done with other plants.
Another thing the bonsai-grower must do is to trim（修整）the roots and branches of the tree regularly.Unless this is done,the plant will not have the proper proportions（比例）and will look unnatural. 39
The last thing one must do is to be careful to keep the trees well-watered.Because bonsai are grown in smaller-than-usual containers,they often need more water than ordinary houseplants do.
As can be seen from the above,the art of bonsai-growing is one which requires a certain amount of time and effort. 40 Imagine having such a tree in your living room and passing it down through several generations of your family.That is exactly what bonsai-growing is all about:establishing a tradition of beauty which lasts for years and years and is a symbol of the beauties of the natural world.
