Don't throw away your garden food scraps. Instead, bring them inside and place them in some water. You'd be amazed at how many veggies and herbs you can re-grow from scraps. Here's 10 of the easiest vegetables to re-grow in water alone! For best results, change the water often and do not let your bowl of water dry out.
Bok Choy
Simply cut off leaves at the bottom of the stalks and within a few days, new growth will appear.
Cabbage
Cut the bottom of the head off, & place it in a shallow bowl with a small amount of water. Don't let the leaves get too big, they'll taste better when small.
Carrot Greens
When you've finished eating the root of the carrot plant, save the tops! Cut them down to just a few inches and watch them produce new green leaves. Excellent for tossing into salads, make pesto or add to your green juices.
Celery
Cut the stalks down to about 2-3 inches tall. Place base of plant and small roots into a shallow bowl with a small amount of water and watch a new small stalk begin to grow from the center.
Fennel
Cut the stalk down to about 1-2 inches tall, leaving the roots intact. Place in shallow bowl with water.
Garlic Chives
Place a small garlic bulb that has started to grow a green shoot into a shallow bowl of water. Within a few days, you'll be enjoying fresh garlic chives.
Green Onions
Cut the green part off of your green onion, and place the white stalk with the roots intact into a bowl of water. The stalk will regrow the green section that you cut off.
Lettuce
Remove the bottom of the head, leaving it about 1-3 inches long. Place that into a shallow bowl with water. It will regrow small lettuce leaves in the center.
Leeks
Place the bottom section of the stalk, about 2-3 inches long, into a bowl with water. It will re-grow the center portion of the leek.
Lemon Grass
Plant the same as you would a leek. Remove all but 2-3 inches of the stalk, place in about 1/2 inch of water and watch it regrow from the center.
