Head-Form and Leafy Veggies: The Overachievers
These veggies are like the straight-A students of the plant world - easy to grow and quick to show results.
Lettuce (including Romaine and Bok Choy)
- Cut off the bottom 1-2 inches from the base of the lettuce head.
- Place it in a shallow bowl with just a bit of water in the bottom.
- Keep the bowl somewhere that gets good sunlight and mist the leaves with water a couple of times each week.
- After 3-4 days, you'll notice roots beginning to appear along with new leaves.
- When this happens, you can transplant your lettuce into soil.
Celery
- Cut off the bottom or base of your celery, leaving about 1-2 inches.
- Lay it in a bowl with just a bit of warm water in the bottom.
- Keep the bowl in direct sunlight as long as possible each day.
- After about a week, you'll begin to see the leaves thickening and growing along the base.
- When this happens, you can transplant your celery in soil and wait for it to grow to full length.
Bulb and Bulb-like Vegetables: The Underground Superstars
These veggies are the phoenixes of the plant world - they just keep coming back!
Green Onions
- Cut off the white base with the roots intact, leaving about an inch of the onion.
- Place it in a container of water and put it in direct sunlight.
- Change the water out every few days.
- The green part will continue to grow - just snip what you need and allow it to regrow.
Lemongrass
- Cut off the base of the lemongrass, leaving about an inch.
- Place it in a glass bowl or jar with enough water to cover it.
- Leave it in the sunlight.
- After about a week, you'll notice new growth.
- When this happens, you can transplant your lemongrass in a pot or your herb garden.
Garlic
- Take a single clove from a garlic bulb.
- Plant it with the roots facing down in potting soil, about 4-6 inches apart from other cloves.
- If planting outside, do so in fall before the first frost.
- If planting inside in a container, you can do it any time, but you'll only get garlic greens, not a full head.
Onions
- Cut off the root end of the onion, leaving about an inch of onion attached.
- Place it in a sunny location in your garden or in a container filled with potting soil.
- Cover with soil but leave the top exposed.
- For best results, plant in the garden in early spring.
Fennel
- Cut off the bulb's base, leaving about 1 inch of the fennel attached.
- Place this base in a container with about a cup of water.
- Put it somewhere that gets good sunlight, like a windowsill.
- Change the water every couple of days.
- When you see new roots growing strong and green shoots coming up from the center of the base, you can transplant it into soil.
Root Crops and Root-like Veggies: The Hidden Gems
These underground dwellers are full of surprises. With a little patience, you'll have a whole new crop!
Ginger
- Soak the ginger root in warm water overnight.
- Plant it sideways in a pot filled with rich soil, about 2-4 inches deep.
- Place the pot in a spot that stays warm and doesn't get too much bright sunlight.

- After a few months, you'll have new ginger roots to harvest.
Turmeric
- Plant turmeric just like ginger, sideways in the soil.
- It prefers temperatures well into the 70s and 80s Fahrenheit.
- You may need to use a grow light and/or heating lamp for best results.
- Keep the plant consistently moist, spraying and watering it regularly.

Potatoes and Sweet Potatoes
For regular potatoes:
- Cut the potato into 2-inch pieces, making sure each piece has at least 2-3 "eyes."
- Let them sit at room temperature for a day or two to dry out.
- Plant them about 4 inches deep in soil, making sure the eyes are facing up.
- It will take a few weeks before you see the plants begin to grow.
For sweet potatoes:
- Cut the sweet potato in half and suspend it using toothpicks above a container of shallow water.
- Roots will begin to appear in just a few days, and sprouts will be seen on top of the potato.
- Once the sprouts reach about 4 inches in length, twist them off and place them in a container of water.
- When the roots from this container reach about an inch in length, you can plant them in soil.
Carrots, Beets, and Other Root Vegetables
- Cut off the top of the vegetable, leaving about 1/2 inch of the root attached.
- Place the scrap in a shallow container of water, cut side down and leaf end up.
- Put the container in a sunny windowsill and change the water every couple of days.
- In a few days, you'll see the greens start to regrow.
- Once the roots are well-established, you can transplant to soil if desired.
Easy-to-Regrow Fruits: Yes, Fruits Can Join the Party!
Who said vegetables get to have all the fun? These fruits are ready to sprout and grow!

- Keep the soil consistently moist.
- When seedlings are large enough to handle, transplant them to larger pots or into your garden.
Citrus Fruits (Lemons, Limes, etc.)
- Clean the seeds well and plant immediately (citrus seeds lose viability quickly when dried out).
- Plant about 1/2 inch deep in moist, well-draining potting soil.
- Cover the pot with plastic wrap to create a greenhouse effect.
- Place in a warm area until seeds sprout.
- Remove the plastic and move to a sunny spot.
- Be patient - it can take several years before you see any fruit!
Cherries, Apples, and Peaches
- Clean the pit or seeds thoroughly.
- For cherries and peaches: Place the pit in a sealed container or plastic bag with slightly moist potting soil.
- For apples: Remove the seeds from the core and let them dry out.
- Place the container or bag in the refrigerator for about 12 weeks to stratify the seeds (simulate winter).
- After stratification, plant the pit or seeds in a pot with good potting soil, about 1/2 inch deep.
- Keep the soil moist and place in a warm, sunny location.
- Be patient - it can take several weeks for sprouts to appear, and several years before you see fruit!
Strawberries
- Choose a fresh, fully ripe strawberry.
- Carefully cut the outer skin (containing the seeds) off the berry, or extract seeds using tweezers.
- Place the skin or individual seeds in a small container filled with potting soil.

Your Kitchen Scrap Garden Awaits!
Kitchen scrap gardening is more than just a money-saving hack—it's a way to connect with your food, reduce waste, and bring a little green magic into your life. Whether you're aiming for a full-fledged vegetable garden or just want to add some fresh herbs to your windowsill, there's a kitchen scrap project for everyone.
Remember, not every scrap will successfully regrow, and that's okay! The joy is in the process and the occasional surprise success. So next time you're chopping veggies or enjoying a piece of fruit, pause before tossing those scraps. With a little water, sunlight, and patience, you might just be holding the beginnings of your next garden adventure.
Attention All Plant Lovers!!
To all you foliage fanciers out there who aren't necessarily in it for the harvest, many kitchen scraps can be grown purely for their aesthetic value. Avocado plants, for instance, make stunning houseplants with their large, glossy leaves. Pineapple tops can develop into exotic-looking potted plants. Even carrot tops can create delicate, fern-like foliage. So if you're looking to green up your space without breaking the bank on expensive tropicals or trendy succulents, your kitchen scraps might be the perfect solution!
Your kitchen adventures can take you on a global tour:
- Mediterranean Charm: Fig cuttings can grow into beautiful indoor trees, while pomegranate seeds might surprise you with their vibrant foliage.
- Tropical Delights: Mango and papaya seeds can sprout into lovely houseplants. Imagine the conversation starter of a sugar cane stalk growing in your living room! And don't overlook the unique beauty of a tamarind seedling.
- Middle Eastern Marvels: Try growing arrowhead or Chinese dasheen (taro) for their striking leaves. The Chinese red date (jujube) can make an interesting bonsai project, while carob seeds (St. John's bread) can grow into attractive potted plants.
- Asian Aesthetics: Lychee seeds can develop into glossy-leaved plants, and who wouldn't want a kiwi vine climbing up a trellis by a sunny window?
- Exotic Experiments: Push the boundaries with black sapote or cherimoya seeds. The star-shaped leaves of the Chinese star apple could add a unique touch to your indoor jungle. And don't forget the delicate beauty of a loquat seedling!
- Herbal Accents: The feathery fronds of fennel, delicate flowers of coriander, or star-shaped blooms of anise can add texture and interest. Mustard and sesame microgreens offer quick bursts of green.
Remember, while these plants may not fruit indoors, their foliage alone can transform your space into a lush oasis. With a little creativity and patience, your home can become a global botanical garden, all starting from the humble beginnings of your kitchen scraps.
So next time you're enjoying exotic fruits or spices, pause before discarding the seeds or pits. That little bit of "waste" might just be the beginning of your next green adventure. Happy growing, and may your home be filled with the beauty and wonder of plants from around the world!
Happy growing, and may your kitchen scraps bring you bountiful harvests and beautiful greenery!
