Observing how some vegetables magically regrow from scraps is a fascinating plant science project you can do at home with the kids even if you don’t have a yard! The boys and I are watching a few items regrow (or not in one case) in our small window greenhouse.
I remember growing vegetables from scraps in my elementary school classroom 35 years ago (don’t do the math, please). Then, in my college years I toted around a small indoor avocado tree I had grown from a pit. Of all the indoor gardening activities, it is one of the most satisfying. Garbage turns into stuff you can eat! Kind of cool, if you ask me. My older son enjoyed growing root veggies in his DIY see-through planter, but I think he may be liking this even more.
This is what it looks like now (including our coffee bean plant and a random succulent!). We started with celery and scallions, which should the most immediate results, and thus the best to lure kids into the magic. Cut the celery off near the base and the scallions just near the green line and sit the bottoms in water.
Later we added sweet potato and avocado. Both should be suspended in water using toothpicks.
The avocado pit is stalled, I think because the window is not warm and sunny enough yet. We’ll see. I’ll probably try a new one in a few weeks. I’ve had great success with avocado pits in the past.
The sweet potatoes are eeking along. We can see some teeny tiny roots and sprouts. Part of the fun of plant science with kids is pitting (pun) one plant against another and seeing which ones “win” the race to grow. That’s how we’re conducting our kitchen seed and bean race and it’s been part of the discussion with the boys about the veggie scraps, too.
There are lots of other veggies scraps you can grow in your window without ever touching a bag of soil. Check out these how-tos:
- Carrot tops, parsnips, beets — any of these types of root veggies
- Bok choy and romaine lettuce: just like celery
