First off, a word of caution; when we say you can grow carrots from carrots, we mean the plant, not the root vegetable. The orange, kid friendly vegetable is actually a taproot and once removed from the plant, it can’t regrow. Make sure you explain this to your kids before your project begins. Otherwise, if someone thinks they’re growing real carrots from carrot tops, they’re likely to be disappointed. There are three different ways to grow carrots from carrots. All have a high success rate and all are fun for kids.
You can grow carrots in water. Cut the top from a grocery store carrot. You’ll need about one inch of the root. Stick a toothpick into either side of the carrot stump and balance it on top of a small glass. Use an old juice glass for this since you’ll probably end up with mineral stains. Fill the glass with water up to and barely touching the bottom edge of the stump. Set the glass in a light, but not sunny window. Add water to keep it touching the edge and watch the roots sprout.
