8. Plant sprouted potatoes.
Instead of throwing away sprouted potatoes, carefully cut around the sprout or “eyes” so that you have a piece of potato that is about the size of a chicken egg. Leave the pieces out for a couple of days, then dig a hole in your garden about four inches deep and plant the potato sprout-side up. Don’t water the potato until the sprout breaks through the soil.
Note: You can also grow vegetables from sprouted garlic and other leftover vegetable scraps. Check out 7 Vegetables You Should Never Pay For for more details.
