An American group developed the rooftop gardening in the early 1980s. The group is known as ECHO.
This idea was to help people living in cities who did not have land to grow vegetables. And now it is
becoming more and more popular in many other countries.
To build a rooftop garden, four things are necessary. You need a roof strong enough and four pieces of
wood to build a box, and also you need grass cuttings in which to plant your garden and a thin piece of plastic
on which to put the cut grass.
Begin by testing your roof to make sure it is strong enough. Cut and collect some grass. Cover the roof
with a thin piece of plastic. Then you build a box from the four pieces of wood. The box has no top or
bottom. It should be about 8cm deep. It can be as long and as wide as needed. Put the box on the plastic.
Then fill in with the cut grass. Water the grass and push it down by walking on it. After about three weeks,
the rooftop box is ready for planting.
Put the seeds (种子) directly into the wet grass. It is important that the grass is kept wet until the plants
begin to grow. When the plants are growing, you will need to water them every day unless it rains. And birds
must be prevented from eating the seeds or new plants. They will also need some liquid fertilizer (液体化肥).
You can make your own liquid fertilizer if you can get waste (粪便) from chickens. Put the chicken waste in
a cloth bag. Then put the bag in a big container (容器) of water. After about one week, the water becomes a
good liquid fertilizer.
The rooftop garden is a good place to grow peas, tomatoes and onions. If the box is deep enough, potatoes
and carrots will also grow.

| An old farmer lived with his grandson. Each morning, the 1 got up early and read his Bhagavad Gita (薄迦梵歌). One day the grandson asked, "Grandpa! I try to read the book like you 2 I can't understand it, and I forget it easily. What's the 3 of reading it?" The grandfather said, "Take this coal (煤炭) basket down to the 4 and bring me back a basket of water." The boy did as his grandfather 5 , but all the water ran 6 he got home. The grandfather laughed, "You'll have to move faster next time." This time the boy 7 faster, but again the basket was empty. He told his grandfather that is was 8 to carry water in a basket. He wanted to use a bottle instead, but the old man said, "I just want a basket of water. You're not 9 hard enough." The boy wanted to show his grandfather that the water would surely run. He again put the 10 into the river and ran hard. But there wasn't anything in it again. He said 11 ,"Look, grandpa, it's useless!" "Watch the basket." said the grandfather. For the first time the boy 12 the basket was different. It had changed from a dirty old coal basket into a 13 one, inside and out. "Boy, you might not understand or remember 14 when you read the book, but when you read it, you will be 15 , inside and out. That's what you got from it." | ||||
