9 Grocery Store Vegetables You Can Regrow (Even Without a Green Thumb)

If you feel like things are getting tough out there, you're not alone. Many of us are focused on saving whenever we can, especially on food. 

One way to keep more cash in your wallet is by cutting down your grocery expenses, but there's only so much couponing we can each handle. But what if there was a way to grow your own food at home for free — just with the leftovers you already have?

You don't have to have a huge plot of land to grow your own food — you just need to know where to begin. Here's an overview of how to grow a selection of your favorite vegetables by using the scraps that would otherwise end up in the trash. 

Green onions — or scallions, if you're fancy — are an easy way to add bite to any of the recipes on your meal plan (and if you don't already meal plan, it's time to consider starting — it's a smart money move if you want to lower your financial stress).

When it comes to growing green onions, there's not much to it. Just trim the onion with the roots still intact and fill a jar with just enough water to cover them. Then, place your scraps in direct sunlight (on a windowsill works great) and wait.

It should only take a few days for your new onions to sprout. To encourage healthy growth, change the water once a week.

A hearty root vegetable, beets are known for their vibrant pink or even golden color and ability to be pickled. While beets are most commonly roasted, boiled, and eaten, the leafy part of the vegetable can also be eaten and makes a great addition to salads or stews.

Thankfully, it's easy to grow beets from scraps — you just need to have a few tricks up your sleeve.

For best results, start by washing the beet and cutting off the leaves. Place the severed beetroot in a shallow dish and cover it with just enough water to cover the beet's top. In a few days, you should see new leaves start to form.

Celery is not only an underrated soup or stew ingredient but also makes a great crunchy snack. To grow celery from scraps, you'll need to retain the base of the celery (the part that usually carries a lot of dirt and gets thrown out).

Then, place the celery in a dish and cover it with an amount of water that allows the top of the celery to stick out above the liquid. You can use a toothpick or two if the celery needs help balancing.

Make sure your celery gets some sunlight, and then watch it grow. If you'd like, you can plant the celery in soil after a week or so.

Bok choy, also known as Chinese cabbage, is a highly nutritious leafy vegetable that works wonderfully in soups and stir-fry dishes. 

Bok choy can be tough to find in some supermarkets, so it helps to be able to regenerate your own at home. You'll notice the method for growing bok choy closely resembles that of celery. First, cut off the dark greens from the bok choy's stem (you should have around an inch of vegetable left).

Then, balance the bok choy so it's half-submerged in water, place it near light, and wait. You can plant the bok choy in soil if roots appear.

Romaine lettuce is one of the most common leafy greens in the United States, making an appearance in around 30% of all salad consumption. But before you make romaine lettuce a part of your weekly grocery lists, try regrowing your own. 

Romaine can easily be grown by placing the stem of your lettuce in a shallow dish of water and placing it near sunlight. You won't be able to regrow an entire head of lettuce, but when it comes to lettuce, a little goes a long way.

While garlic is often cited as an herb, it is actually a vegetable, so it makes sense that you can easily regrow it like the other vegetables on this list.

First, purchase some organic garlic. This kind is more likely to resprout for you. Then, you'll want to separate a few garlic cloves and place them in the soil, with one end sticking up in direct sunlight.

Make sure to water and fertilize your garlic, but don't overwater. It should sprout in three to four months.

Carrots are naturally suited for at-home regeneration — well, the green part is, at least. You may not be able to grow an entire carrot from a scrap, but you can grow the leafy greens that sprout from the top. And carrot leaves are edible and delicious. 

Just stick a carrot top in a jar of water and put it in indirect sunlight. Its leaves will grow and often flower within a matter of days.

To plant your own tomatoes, you can harvest the seeds from any store-bought variety. For best results, you'll need to ferment the tomato seeds by letting them sit in water in a warm place for a number of days. 

Once the seeds have grown mold, rinse them and dry them off before planting them in soil and waiting for your plant to grow.

You can grow sweet potatoes from their sprouts, which are known as "slips." Encourage the growth of slips on your sweet potato by placing it in water and setting it in a warm place like a windowsill.

Then, once the chance of frost has passed, you can plant these slips in the ground and enjoy fresh sweet potato crops.

You can save a lot of money by strengthening your green thumb, and hopefully, you feel more encouraged to do so.

However, a trip to the grocery store isn't avoidable altogether. To ensure you make the most of your trip, consider using your top cash back credit cards to earn more when you shop. 

This, combined with reusing food, will get you a long way when it comes to cutting back on your monthly food budget.
