Here's a departure from my "usual" topics: Foods you can grow from scraps
Yes, right at home and often in your own kitchen, you can grow onions, pineapple, tomatoes, ginger, potatoes, celery, avocados, apples, carrots, and more! And these represent the icing on the free food cake.
Note that you probably can't really grow edible apples because of the nature of apples these days, and we're talking years before avocado trees or pineapple plants bear fruit, but it is interesting and might be worth it down the road. So give it a shot! ~~GH
