根据下图示意图提示内容，写一篇100字左右的短文，说明如何移植植物。
When a plant grows too large for its original place, it needs to be replanted in another pot. You can do this quickly and easily if you follow the following instructions.
First, you should cover the bottom of the pot with some small stones. Then put two or three inches of soil on the small stones. You then dig a hole in the center of the soil and drop the plant into the soil. Next, you should add more soil until it almost reaches the top of the pot, press the soil with thumbs. Finally, water the plant.
Plants need sunshine, water, soil and our love as well.

3.说明的次序非常重要。合理的次序会使条理清楚，脉络明晰。
