20．
"Soon，you're going to have to move out!"cried my neighbor when seeing the largest tomato plant known to the world，or at least known in my neighborhood．
One tiny 9-inch plant，bought for 1.25dollars 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 that can be used 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 to be even more perfect for tomatoes．The daily watering coupled with full sun and regular fertilizing（肥料）have turned the little plant into a tall bush．
Now the task I face in harvesting the fruit is difficult．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 draw back my hand without dropping the prize so dearly won．I found two beautiful white roses completely hidden as I picked tomatoes in June． But they were weak and the leaves already yellow for shortage of light．
Here I face a painful small decision：tear up a wonderful and productive tomato plant that offers up between ten and twenty 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．
