Check out this fun article I stumbled upon, 16 Foods That’ll Re-Grow from Kitchen Scraps. Some crops include onion, leeks, garlic, and the one that surprised me the most, pineapple.
It’s interesting to see how some plants will grow out of what we normally consider scraps or the waste parts thrown out when cooking. This type of information is applicable to anyone gardening for fun or even for small-scale farmers that don’t necessarily always have access to new seeds or time/space to let certain crops such as onions go to seed. Pretty neat!
