Grow a Food Scrap Garden

Have you been wanting to start a garden? Check out these cool ways to grow fresh vegetables using leftover scraps!

Here are ‘before’ and ‘after’ pictures of the onions Tiana is growing in her backyard!


  • Vegetable and fruit scraps
  • Water
  • Small cups/dishes
  • Pots/planters
  • Soil



You will need a two inch peel of potato skin with two or three eyes on it to start a new plant. Dry the skin overnight and plant four inches deep in soil with the eyes facing up. 

Celery, lettuce, cabbage, and green onions

Use the bottom of these veggies to sprout new ones! Place one in a dish or cup with about a half inch of water in the bottom. Keep the plant on a sunny windowsill and water daily. When you see roots and thicker leaves, transplant into a pot with soil either outside or on a windowsill. For green onions, the plant can grow large enough to use without moving to soil. 


Take the bottom half inch of a full onion and plant it in soil with the cut part facing up. Keep it in a warm, sunny area. 


Rinse and dry leftover tomato seeds overnight. Plant them in potting soil and keep in a sunny area. When the sprouts are a few inches high you can move the plant outdoors or move it to a bigger pot to keep indoors in a warm, sunny area. 


Plant pepper seeds directly into soil either inside in a warm, sunny spot or outdoors if the weather permits. Save seeds from each crop to plant more!
