Did you happen to watch the video I posted on February 12 entitled "10 Vegetables You Can Regrow from Kitchen Scraps to Create a Recurring Harvest"? I had never heard of this, but thought it would be a great way to supplement our vegetables if it worked, so on that day (Sunday) I put the remains of four green onions and one bunch of celery in water to see what would happen. The next day I added two heads of romaine lettuce. Here they are on Monday when I added the lettuce. You can see the green onions have already begun to grow!!
In a couple of weeks I will post another photo of the progress. I thought you might be inspired to try growing vegetables from kitchen scraps, too, if you saw how easy it is and how quickly they reach harvest level.
