Bag Garden Bag Gardens are a great way to grow lots of vegetables, even for farmers who only have a small plot of land. A sack is filled with a mixture of soil and compost and a pillar of stones down the middle. The sack is held up with sticks and holes are cut down the sides. Different types of vegetables can then be grown in the top and down the sides of the bag, providing a healthy diet for farmers and their families. Learn how to make your own Bag Garden.
