A garden that’s just right for you

Have you ever visited a garden that seemed just right for you, where the atmosphere of the garden appeared to total more than the sum(总和) of its parts?    36   . But it doesn’t happen by accident. It starts with looking inside yourself and understanding who you are with respect to the natural world and how you approach the gardening process.

Some people may think that a garden is no more than plants, flowers, patterns and masses of color. Others are concerned about using gardening methods that require less water and fewer fertilizers(肥料).    38   . However, there are a number of other reasons that might explain why you want to garden. One of them comes from our earliest years.

●Recall(回忆) your childhood memories

Our model of what a garden should be often goes back to childhood. Grandma’s rose garden and Dad’s vegetable garden might be good or bad, but that’s not what’s important.    39   --how being in those gardens made us feel. If you’d like to build a powerful bond with your garden, start by taking some time to recall the gardens of your youth.    40    then go outside and work out a plan to translate your childhood memories into your grown-up garden. Have fun.
