The idea of regrowing your groceries sounds too good to be true, but in some cases it really is possible. Check out these step-by-step instructions for regrowing common grocery items.
01 of 07
Cut the last inch off of each green onion (this will give you the bulb and roots). Plant these in a flower pot or in your garden. Be sure to cover the bulbs completely, and to leave a portion of each stem sticking out above the soil. Water regularly, and watch your green onions grow back.
To harvest, simply cut off as much of the green stalks as you need. If you leave the white bulbs in the plant, they'll continue to regrow more greens. Expect to get three to four cuttings off of your green onions before you need to plant more.

Cut the bottom inch off of a bunch of celery. Place the celery piece in a bowl, cut side facing up, and add a bit of water (just enough to submerge the bottom of the celery).
Move the bowl to a sunny spot, and wait for leaves and roots to form (this should only take a few days). Then, plant the celery in your garden, covering everything but the leaves.
Wait for the celery stalks to grow back. Then, cut off as much as you need. As long as you leave the root in the ground, your celery will grow back again and again.

Soak your ginger overnight. Then, cut it up into pieces. Make sure you have a couple growth buds on each piece (they're the little bumps on the end of each finger). Plant your ginger with the growth buds pointing up or to the side (you just don't want them facing down).
Then, water regularly. Ginger likes to have moist, but not soggy soil at all times. To harvest, simply dig up one of your rhizomes (pieces), and cut off what you need.

Leaf Lettuce and Greens
Any time you harvest leaf lettuce from your garden, pick the outer leaves but leave the inner leaves untouched. As long as the crown of the plant remains undamaged, your lettuce will continue to produce new leaves all season long.Continue to 5 of 7 below.

Cut off the top of a pineapple, and carefully scoop the fruit off of the underside (the crown). Take a small slice from the crown to expose the root buds (the small dots around the outer edge). Be careful not to go too deep with your cuts.
Then, strip the leaves from the bottom inch of the crown, and set the whole thing aside for a few days to allow the cut side to heal and dry out. Plant your pineapple crown in soil that drains well, and place in a sunny spot.
Water once a week (more often in the beginning). Your plant will root and begin to grow within a couple months but expect it to take 2-3 years for the fruit to develop.

Cut a one-inch (approx.) chunk from a potato that includes one or two eyes. Give the piece a day or two to dry out and skin over. Then, plant with the eye (or eyes) facing up.

Bury all or part of a sweet potato under a thin layer of soil. Wait for slips to grow from the sweet potato and reach at least four inches in height. Pull the slips off, and plant them.
