You see these gorgeous papas? They were grown in a perforated garbage can filled with soil in our backyard. You basically take small potatoes or cut up potatoes that have a least two eyes and stick them in soil to make new potatoes that taste better than anything you can get at the store.
Green onions 2
This is the first thing my hubby ever showed me how to grow. If you have a potted version of green onions, you can cut from the top and then let them grow back indefinitely. Otherwise, you can put the roots of the green onions in a glass of water and let them regrow. So easy!
Regular onions are only a little bit harder to grow than green onions as evidenced by the fact that they seem to want to grow all by themselves if you don't use them fast enough. You simply cut off the root end leaving about an inch of the actual onion and plant that baby root down in soil. Don't forget to water.
Did you know that if you stick the bottom of a celery stack in water, chances are it will begin to regrow? After three days you can stick it in soil to keep it growing. FYI, the celery you put in your bloody mary won't grow, so you may as well eat it.
Basil & mint 6
Regrowing basil or mint is as easy as taking a cutting and putting it in water until it roots and then putting it in soil.
