Buying fresh produce can feel expensive especially if you’re purchasing fruits or vegetables in their offseasons. There are however many fresh foods that you could buy once and regrow again and again in your own home. All it takes is a little dedication, a bit of effort and the motivation to do it. There are some vegetables that you can grow simply in only water and some that need to start in water and then transferred to soil soon after.

Regrowing foods could be a great school project for teachers because not only is it educational but it is a great skill to know how to grow your own fresh produce. It would also be an awesome activity that you could do with your children especially over the summer months when you’re aimlessly trying to find things to keep you all busy. Regrowing your own produce will keep you busy but it could also save you money not to mention is a great way to get organic produce at a low cost. Here are 18 foods you can buy once and regrow again.

1. Lettuce

When regrowing vegetables make sure to try regrowing lettuce. It is super easy and can regrow only using a bowl of water! Romain lettuce seems to be the most successful but other lettuces will work too. What you need to do it cut off the bottom of your head of lettuce and place it in a small bowl.

Lettuce will prefer a shallow bowl and make sure it is wide enough so that it fits comfortably. Make sure to check your water every couple of days. You will want to look out for low water level if it’s low top it up. You also need to look out for slimy water, if this happens make sure to replace the water. You should have half a head of lettuce in around two weeks.



2. Garlic Greens

It is important to note if you want to grow a bulb of garlic you will have to do that outdoors. However, you can regrow garlic greens indoors just from bulbs of garlic you have on hand. They have a lighter flavor than fresh garlic and make a delicious seasoning or garnish for many dishes.

To grow them inside you’ll want to start by planting three or four garlic cloves in potting soil. Make sure they are placed on a window ledge that gets a lot of sunlight and then makes sure to water them lightly. The garlic greens should grow within 10 days and can be snipped to use in your meals. PHOTOS AND TUTORIAL HERE: MARTHA STEWART

3. Tomatoes

Tomatoes can be sweet, juicy and delicious and are quite easy to grow on your own too. The next time you buy a tomato and decide to use it consider taking some of the seeds out to turn that one tomato into a beautiful plant.

You will want to take the seeds and put them on a paper towel so they can dry. Once they are dry, place the seeds in some potting soil to grow indoors. When there are a couple inches of growth it will then be a good idea to place the tomato plant outside in a sunny area. Make sure to water regularly, and take precautions if you have any pesky animals in your yard.

4. Pineapple

Pineapple is known for it’s juicy and sweet flavor but did you know you can buy this delicious fruit and grow it again! It’s important to know that pineapple thrives in warmer climates and make sure to keep your plant away from freezing temperatures. For a pineapple plant to thrive it will need full sun for most of the day.

To begin, save the top (also known as the crown) of the pineapple and cut off the rest of the fruit as well as the rind. Place the crown in a cup of water so that the base can sprout roots. Once you notice root growth you can then transplant your pineapple crown into a pot with potting soil. You’ll want to make sure you plant it in a pot that is at least 10 to 12 inches wide so it has room to grow.

5. Green Onion

Green onion compliments many dishes as a garnish and even can add a bit of flavor to your salads. They’re another fresh food that is relatively easy to regrow simply in water.

Make sure to keep the bottom white part of the onion, if there are any roots still intact make sure to keep them as well. Choose a tall slender glass and set the base of the onion in the water. Make sure to check your water regularly, change if needed and enjoy watching your fresh green onion grow.

6. Carrot Greens

Instead of putting your carrot tops in the compost consider regrowing them for their greens. Carrot greens although a little bitter in taste, are great mixed into salads and offer a great source of nutrition. You could even consider blanching them to help lessen the bitter taste and serve them with a meal.

To regrow your carrot greens cut off the top leave about one to two inches. You can either place in a shallow bowl with about one inch of water, only the carrot top should be in the water. Your carrot top will begin to grow roots and the tops should sprout with the greens soon after. If you like baby greens you can eat as is or if you prefer the taste of mature greens consider planting your sprouted carrot top and harvesting after.

7. Potatoes

If you have ever stored your potatoes for a little while I’m sure you have noticed that they begin to sprout. Instead of tossing these potatoes consider using them to regrow your potatoes.

You will want to cut the potatoes into halves and ensure that each half has at least two eyes also known as the sprouts. You will want to let the potato pieces dry at room temperature. It can take anywhere from overnight up to a couple days. Once they are dry to the touch you’ll want to plant them in eight inches of soil. Make sure each potato piece is at least one foot apart. You’ll want to make sure the top of the potato plant, or known as the vines have died off before you begin to harvest your potatoes.

8. Celery

Celery, like lettuce, can thrive in water. To regrow celery you’ll need to cut off the bottom at least two inches and place in shallow water. You’ll want to make sure the celery get’s direct sunlight. You should see growth within only three to four days.

You’ll continue to get regrowth from the center often but if you want a full stock of celery you’ll need to transfer it to the soil. If you choose to do this wait until a thick stem of celery has sprouted and then transfer to organic soil. If you choose to grow it outside make sure to be mindful of creatures that may eat it and either enclose it in a wire cage or keep it in a greenhouse.

Then place the cutting into a glass of water and make sure it is placed in a spot that gets direct sunlight. Another great tip is to use a clear glass so you can take note of the root growth. Make sure to change the water every couple of days until the roots begin to grow. Once the roots have grown about two inches in length you can pot the basil in some soil. You can keep the plant indoors as long as it remains in a place with direct sunlight. When you harvest the basil leaves make sure not to take off too many leaves from one stem at a time as this can actually cause the plant to die.
