Nearly five years before，and with the help by our father，my sister and I planted some cherry tomatoes(圣女果)in our back garden.Since then—for all these year—we had been allowing tomatoes to self－seed where they please.As result，the plants are growing somewhere.The fruits are small in size，but juicy and taste.There are so much that we often share them with our neighbors.Although we allow tomato plants to grow in the same place year after year，but we have never had any disease or insect attack problems.We are growing wonderfully tomatoes at no cost!
