Vegetables that magically regrow themselves...

1: You can grow carrot greens from discarded carrot tops.

Select fresh carrots (not baby carrots) that sport a little green on the top. Cut off the top 4cm from the crown of one or more carrots. Place the tops in a shallow saucer, cut side down. Add water so that half of the carrot top is submerged in the water. Place the saucer on a windowsill where it will get light. Add water to the saucer as needed to keep the tops from drying out. The carrot tops will sprout in about 1-2 weeks.

2: A sweet potato will sprout vines that may eventually grow new sweet potatoes.

Place the sweet potato in a jar of water. You want to submerse most of the sweet potato while allowing a couple inches above water. When the sprouts are 10cm long, pull them off the sweet potato. Place the sprouts in water. When the sprout is well rooted, plant in a hill of soil about 20cm high. Keep the plants well watered while the roots are being established.

3: An avocado pit will grow into an avocado tree.

Clean the pit. Insert toothpicks into the pit. Add some water to a small, slender container (preferably glass) until it reaches the top rim. Set your avocado pit (with inserted toothpicks) on the top rim of the container. Wait for the pit to sprout. Change the water every 1-2 days. Over the next 2-3 weeks, the avocado's brown outer layer will begin to dry out and wrinkle, eventually sloughing off. Soon after, the pit should begin to split open at the top and bottom. After 3-4 weeks, a taproot should begin to emerge at the base of the pit. Soon, the avocado will sprout at the top, releasing an unfolding leaf-bud that will open and begin to grow a shoot bearing leaves.

4: You can grow garlic sprouts (which are edible!) from a garlic clove.

Place the budding clove or whole bulb in a small cup or bowl. Add just enough water to cover the bottom of the cup and touches just the bottom of the cloves. The garlic cloves will begin producing roots very quickly after a few days.You can begin harvesting garlic sprouts when the shoots are 6cm tall.

5: Celery can grow from a leftover celery bottom.

Instead of tossing that pretty green base into your bin, place it in a bowl with the cut stalks facing up. Then, add enough water to cover the bottom of the base, but not the whole bulb. Cut off the base of the celery and place it in a bowl of water with the stalk tips facing up. Be sure your water only covers the bottom of your celery, not the entire bulb. Keep your celery in a warm spot, but not in direct sunlight. After about a week, the inner leaves should have turned from yellow and small to green and growing slightly. Your celery is ready to be transferred to a container of soil, or to your garden.

6: You can grow scallions from their discarded roots.

Save about 3cm of your scallion bottoms. Place in a shot glass with some water. Change the water every day and you will see results in a week.
