are circular or irregular in shape.

　　Some gardeners like the appearance

　　of an asymmetrical shape

　　while others work to

　　achieve symmetry in their gardens.

　　For vegetable gardens, the most

　　popular shape is rectangular

　　and vegetables are usually planted

　　in a linear fashion.

　　This method makes it easier

　　to cultivate between

　　the rows of plants.

　　You could mistake some gardens

　　for a meadow when the gardener

　　chooses to include only

　　wildflowers as a choice of vegetation.

　　Including a pond in

　　a garden is popular too.

　　Entrepreneurs are always looking

　　for innovations and gadgets that

　　will attract the attention

　　of devoted gardeners and

　　induce them to spend their money.

　　It has become a huge industry

　　in the last few years,

　　as the baby boomers reach

　　retirement age and have more time

　　to pursue hobbies such as gardening.

　　There are new products patented

　　every year to tempt the gardener.
