     Is it a tree? Is it a bear? If you're looking at a tree in the shape of a bear, it's a topiary (林木雕塑). A topiary

is a tree or a bush (灌木) that is trained into a shape. Growing a topiary garden takes both time and skills.

     A topiary gardener should make a drawing first. The drawing shows the final shape that the gardener likes.

The gardener then chooses a bush for the topiary. It may be one that just planted or one that is already in place.

     In June of the plant's first year, the gardener looks for new leaves. When the leaves grow, it's time to shape

(给……造型) the bottom of the bush. It needs about five years. The top is not trimmed during this time. In the

fifth year, the bush grows tall enough for shaping. Then the gardener begins to shape the whole bush.

     Once a topiary has been started, it needs care all year. In the summer it must be cut many times to keep its

shape. This cutting also helps the bush grow. In the winter the bushes don't grow. The gardeners have to brush

snow of the plants, or snow may hurt some parts of them.

     Topiary gardening is very old art. The Romans did it in the first Century. In the sixteenth century, people in

Europe like topiaries too. By the late 1600s, topiaries were also grown in America. Today it's popular in many

parts of the world.
