根据短文内容选择正确答案。

       You don't need a huge piece of land to have a garden.  A small square of backyard or a flowerpot
will be OK! With a little bit of care, you and your family can enjoy tomatoes or flowers.
       You will need:
       A seed;(幼苗) tomato or flower, a trowel, water, a flowerpot with soil or a backyard.
       Here's how:
       If you use a flowerpot, be sure your flowerpot will have enough space for the roots to grow. Fill your
flowerpot about three-quarters full with soil. If you are planting in your backyard, dig a hole with your
trowel.  Make sure that the hole is big and deep enough to hold the roots of your plant.  Put the plant in
the hole, and then fill in the soil around the roots. Water your plant and make sure that your plane can get
enough sunshine. A little water is OK. Water it every few days.
