My Favourite Vegetable

Let me tell you how to grow carrots. First, we plant carrot seeds in the warm soil in spring. Then, small green leaves grow out from the seeds. Next, the leaves grow bigger and bigger, and the orange roots grow under the ground. Finally, we pull up the carrots by the green leaves when they are full-grown. We eat the root part of carrots.
