| 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. |
