Sack of Potatoes

 Sub-Project: Growing vegetables in usual places

Description: Why not grow your own potatoes? Choose some bio potatoes as these types of potatoes haven’t been treated by fungicides and can still sprout. Take a big plastic bag or permeable sack making sure that you make additional holes in it to allow the water to drain out. A black rubbish bag or sack of rice make great containers. Roll the bag 15cm from the ground and fill with gardening soil. Take 3 to 5 potatoes, of different varieties, that have begun to sprout, pointing the sprouts towards the top. Sprinkle some ash on top to provide the needed nitrogen. Make sure you put the bag in a sunny spot and water it regularly. Once you see the first leaves popping up, add more soil. Continue this process until the bag is completely filled up to the brim. In a few weeks the plants will start getting yellow which means that the potatoes are ready to be picked! Teacher’s tip – select a variety of potatoes, like the purple potato or “rosa” potato.

Collaborative Project: Did you know that there is a whole category of carrots, “rondo carrots” to be exact, that are also called “windowsill carrots” because people plant them in yogurt cups and leave them on the windowsill to grow? How many unusual places can you think of growing your vegetables? Come on, don’t be a sack of potatoes, share your ideas with another classroom!
