Yes, you can grow food from food. These vegetables, fruits, and herbs regrow themselves, and some even grow in water alone. By regrowing your favorite produce, you'll spend a little less time in the produce aisle and a little more time in your kitchen and garden. Bonus: You'll also save some cash in the long run.
There's nothing better than a batch of homegrown basil (did someone say pesto?). The fact that you can regrow basil in your kitchen makes it even better. Cut the plant a few inches below its highest set of leaves. You'll want a few inches of bare stem to reach the water.
Place the trimmings in a jar or vase and fill with water. Keep the plant near natural light but not directly in light to be sure that your herb doesn't burn. Transfer to a pot once hairlike roots have sprouted.
Grow lettuce straight from the fridge! Go ahead and eat your batch of lettuce, but leave the central part of the vegetable untouched—this section holds all of the power in producing new growth. Cut the leaves about an inch from the bottom of the lettuce bunch.
Place lettuce stem in a shallow dish. Change the water every couple of days; after 10-12 days, you'll have bits of lettuce perfect for making small salads or topping deli sandwiches.
Grow green onions on your windowsill, even while there's snow on the ground outside. To start, cut store-bought green onions near the white root, being sure to leave some of the pale green portion next to the cut root (cutting right at the white part will mean a longer regrowing time).
Place onions, roots down, in a small water-filled glass and set in a sunny spot. Replace the water every 2-3 days; transfer to a pot if you'd like the onions to last longer.
No need to stock up on celery in your refrigerator. Like lettuce, cut the celery base from its stalk, leaving about 1-2 inches of celery. The central part of the celery holds the nutrients for producing new stalks.
Place the cut celery base into a bowl of water. Change the water every other day to keep the roots fresh. Now you can enjoy quick-and-easy ants on a log whenever you please!
Plant this veggie right in your garden! Regrowing onions is simple. Start by cutting the onion at the root, then place the onion root in the soil, cut side up. Cover the onion in about an inch of soil; water, then let the roots regenerate themselves. Once roots start to appear, remove the original onion bottom and let the roots grow out.
