20 Vegetables and Herbs You Can Grow Indoors from Scraps

20 Vegetables and Herbs You Can Grow Indoors from Scraps

Sure, you’ve heard that buying organic food over the genetically modified or pesticide exposed versions is ideal for your health, but it can get costly. Due to the limited supply of organic foods as well as the additional labor and maintenance required to produce them, you may be paying 20-100% more for an organic banana!

Fortunately, here are 20 vegetables and herbs you can grow indoors using parts of the produce you would throw away anyways, and this can save you a pretty penny the next time you go grocery shopping.

Romaine Lettuce

Similar to celery, keep the base of your romaine lettuce in a bowl with a ½ inch of warm water. Leave it to sit in direct sunlight, and in a week or two, your lettuce stem will produce fresh, new lettuce leaves for all your great salads. Transplant your lettuce to soil to continue growing. They should be full grown in three to four weeks. This process works for Bok Choy as well.

Garlic Sprouts

Are those tentacles?! Nope, those long green things growing out your garlic are green shoots. You can put them in a little water, under a lot of sunlight and grow a bunch of garlic sprouts. They are milder in taste than garlic cloves, and are great in salads, pastas and as a garnish.


Place chopped off carrot tops in a container filled with a bit of water. Pretty soon, they will begin to sprout delicious greens from the top that are a nice addition to meals. Using a deeper contain and more water, use toothpicks to keep carrots halfway in the water and wait for them to root. Once they root, you can plant them in your garden for a continuous supply!


Like carrots, cut off turnip tops and leave them in a shallow container with water until they begin growing roots. This can take a couple of weeks. Once they’ve sprouted, plant them outside the same way you would your carrots!

Sweet potato

Unlike most vegetables, sweet potatoes aren’t started by seed but by slips (or shoots). Clean and cut a sweet potato in half, then place it half in/half out of a jar full of water using toothpicks. Over a few days, your sweet potato will begin to sprout slips at which point you remove them and place them in water to grow roots. You should have rooted slips with the week. Next, plant them in loose, well-drained soil and water everyday in the first week, and then every other day (or as needed) the following weeks.


With ginger you already have, look for pieces that already have little things growing out of them. With that piece, cut off the parts that look like they’re about to start what’s called a “rhizome” because they’re the key to growing new ginger plants. Growing this food takes minimal effort but does require the right conditions. Warm, slightly humid places like kitchens are perfect. Plant the piece of ginger about 3-5 inches in the soil with its rhizome pointing upwards. Water it regularly. It’s a labor of love and can take up to ten months before you get a sufficient amount of ginger, but its health benefits are more than worth it.


This will definitely take a few years but if you’ve got the time and right climate, why not try? Take a pineapple and cut the flowery “crown” off about an inch below the leaves. Trim around the bottom until you see little brownish bumps (these are the root buds). Before planting, dehydrate the pineapple crown to prevent rotting too soon. Now, with your prepped pineapple cutting, place it in a shallow container of warm water. When the cutting begins to root, replant it into a container with soil and be sure to water once a week. If possible, keep it in a bright, warm place with as much direct sunlight as possible.


Like other herbs, you can regrow rosemary from 5-6 inch cuttings. Place them in water and within a few weeks, there should be enough that have rooted and not rotted. In a 4″ pot filled with damp potting soil, make a 3″ hole with a pen or pencil and place the rosemary cutting gently into it. Because this herb is so delicate, only water it when the soil starts feeling dry. Keep it direct sunlight for 6-8 hours per day because it needs light to flourish. If the soil isn’t dry yet, giving them a quick mist is also okay.


When growing potatoes, you need ones with ‘eyes’ (or slips) growing on it. When you’ve got a potato with a lot of eyes, cut it into 2 inch squares with each piece having a couple of eyes. Leave them out in room temperature for a couple of days to let them dry out to help prevent rotting. In a deep pot, place the cubes 8″ deep with the eyes facing upwards and cover it with another 4″ of soil. As more roots begin to grow, continuously add more soil and keep modestly watered. In as little as 70 days, you should have quite a few potatoes!

To grow this healthy snack at home, cut off the base of the celery and leave it in a bowl with a little bit of warm water. Keep the bowl in direct sunlight, and in a week, your celery base will start to grow leaves. Transplant the celery in soil and watch it grow!


Don’t throw away the bottom of your cabbage head just yet. Just like celery, leave it in a container with an inch or two of water in a well-lit area and wait. Over time, it will start to regrow with no planting required.


Chances are if you accepted the challenge of growing a pineapple, you’ll also love this one. To learn how to grow an avocado tree from a single pit, you can learn how to do so in eight steps right here.
