     "Soon, you're going to have to move out!" cried my neighbor upon seeing the largest tomato plant known

to mankind, or at least known in my neighborhood.

     One tiny 9-inch plant, bought for $1.25 in the spring, has already taken over much of my rose bed,

covering much of other plants, and is well on its way to the front door.

     Roses require a good deal of care, and if it weren't for the pleasure they give, it wouldn't be worth the

work. As it is, I have a garden full of sweet-smelling roses for most of the year. bushes must be pruned (剪枝)

in early spring, leaving ugly woody branches until the new growth appears a few weeks later. It was the space

available(可用的) in the garden that led me into planting just one little tomato plant. A big mistake.

     Soil conditions made just perfect for roses turn out be even more perfect for tomatoes. The daily watering

coupled with full sun and regular fertilizing (施肥) have turned the little plant into a tall bush. The cage I placed

around it as the plant grew has long since disappeared under the thick leaves.

     Now the task I face in harvesting the fruit is twofold; First, I have to find the red ones among the leaves,

which means I almost have to stand on my head, and once found I have to reach down and under, pick the

tomatoes and withdraw(缩回) my full fist without dropping the prize so dearly won. I found two full-blown

white roses completely hidden as I picked tomatoes in June. But they were weak and the leaves already yellow

for lack of light.

     Here I am faced with a painful small decision: To tear up a wonderful and productive tomato plant that

offers up between ten and twenty ripe sweet tomatoes each day or say goodbye to several expensive and

treasured roses. Like Scarlett in Gone With the Wind, I'll think about that tomorrow.
