Zen garden is waterless garden
Zen garden is a garden which doesn't have water. The garden doesn't have pond or stream. Temples of zen denomination in buddhism sometimes have this type of garden.
The garden ground is covered with white sand or gravel. Some rock
are placed on the garden. Old-days people meditated that the waterless
garden was miniature nature. Gardeners (usually monk) draw zigzag on
white sand with rake. It symbolizes water. Rocks are images of
mountains.
As dead leaves or rain make the sand ugly-looking, gardeners have to
sweep and maintained the garden quite often.
