If you’re looking for a creative way to make your food budget stretch further and get a bit of gardening into your life, you might want to try re-growing your used up veggies!
I recently read about re-growing green onions on a windowsill, and was amazed at how simple the process is. You just use the onions normally, leaving the bottom white part and roots intact. You plunk the roots into a jar of water, forget about it on your windowsill for a week or so, and then come back to harvest the regrown green parts. I gave it a try at home, and was stoked on how ridiculously easy it was. This would be an especially great way to extend the life of your food in the winter when you’re often forced to buy most of your food at the grocery store rather than pluck it from your garden.
I was so excited about the success of the green onions that I started looking into whether this technique could be used for other plants. Apparently there are a ton of other plants that can be re-grown this way — who knew?
Here is a rad tutorial on re-growing celery. Like the green onions, you start the stalk sprouting in a dish of water, but after that you transplant it into a container, and it keeps on keeping on from there. Mary and Tim of the blog 17 Apart who put together the celery tutorial also have amazing how-to guides on re-growing sweet potatoes and bok choy on your windowsill.
If bok choy and green onions aren’t exotic enough for you, you can even try re-growing a pineapple in a container! This is a pretty posi way to enjoy tropical deliciousness while keeping the travel distance of your groceries reasonable.
Have you ever tried re-sprouting any of these plants or others? I would love to hear about your experience with this cool technique.
