     Cassandra Feeley finds it hard to manage on her husband's income.So this year she did something

more than a hobby(业余爱好):She planted vegetables in her yard.For her first garden,Ms.Feeley has

put in 15 tomato plants,and five rows of a variety of vegetables.The family's old farm house has become

a chicken house,its residents arriving next month.Last year, Ms.Rita Gartin kept a small garden.This

year she has made it much larger because,she said,"The cost of everything is going up and I was looking

to lose a few pounds,too；so it's a winwin situation all around."

    They are among the growing number of Americans who,driven by higher living costs and a falling

economy(经济),have taken up vegetable gardening for the first time.Others have increased the size of

their existing gardens.Seed companies and garden shops say that not since the 1970s has there been such an increase in interest in growing food at home.Now many gardens across the country have been sold out

for several months.In Austin,Tex.,some of the gardens have a threeyear waiting list.

    George C．Ball Jr.,owner of a company,said sales of vegetable seeds and plants are up by 40%over

last year,double the average growth of the last five years.Mr.Ball argues that some of the reasons have

been building for the last few years.The big one is the striking rise in the cost of food like bread and milk

, together with the increases in the price of fruits and vegetables.Food prices have increased because of

higher oil prices.People are now driving less,taking fewer vacations,so there is more time to garden.
