5 ways to grow endless vegetables from kitchen scraps for a free harvest

1. Green Onions: To regrow green onions, start by cutting the green tops about an inch above the white roots. Place the white roots in a glass or jar of water, ensuring that the roots are fully submerged while the green tops remain above water. Change the water every 2-3 days to keep it fresh; this prevents bacteria from forming. A sunny windowsill is ideal for light, as green onions thrive in bright, indirect sunlight. You can also use a small pot with soil if you prefer; just plant the roots a couple of inches deep. You'll be surprised at how quickly they grow back, often yielding several cuttings per week. A common beginner mistake is not changing the water frequently enough, which can lead to slimy roots and hinder growth.

2. Lettuce and Celery: For lettuce, cut the base about 2-3 inches from the bottom and place it in a shallow dish with water, ensuring the cut end is submerged. Position the dish in a spot that receives indirect sunlight. Change the water every few days to keep it fresh. After about a week, you should see new green leaves sprouting. For celery, the process is similar; cut the base and place it in water. With consistent care, you can harvest new leaves multiple times, potentially saving $2-3 per head compared to store prices. A common mistake is using too deep a dish, which can drown the plant. Instead, keep the water shallow.

3. Potatoes: When using leftover potato scraps, ensure that each piece has at least one "eye," which is where the sprouts will emerge. Allow these scraps to dry for a day or two to form a protective callus over the cut surface, which helps prevent rot. Plant them in well-draining soil, burying them about 4 inches deep. Space them at least 12 inches apart to allow for growth. Water them consistently, keeping the soil moist but not soggy. Each sprouted potato can yield 5-10 new potatoes per plant, making this a worthwhile endeavor. A common mistake is overwatering, which can lead to rot. Always check the soil moisture by sticking your finger in the soil; if it feels dry an inch down, it's time to water.

4. Herbs: For herbs like basil or mint, take 4-6 inch cuttings from healthy plants, ensuring each cutting has a few leaves. Remove the lower leaves, leaving only a couple of leaves at the top. Place the cuttings in a glass of water, ensuring that the stripped part is submerged while the leaves stay above water. Position the glass in a sunny spot. Change the water every few days; roots will typically develop within 1-2 weeks. Once the roots are a few inches long, transfer the cuttings to a pot with soil. Water them regularly, and they will provide continuous harvests. A beginner mistake is placing them in direct sunlight, which can scorch the leaves. Instead, opt for bright but indirect light for optimal growth.

5. Carrots: For carrot tops, cut off the tops of the carrots, leaving about an inch of the carrot intact. Place them in a shallow dish with water, ensuring the cut ends are submerged. Position the dish in a well-lit area, changing the water every few days. You should see new greens sprouting within a week. These greens can be used in salads or as a garnish. If you want to grow new carrots, you can plant the carrot tops in soil after they have sprouted greens. A common mistake is not using fresh carrot tops; older tops may not sprout well. Additionally, ensure the water level is sufficient to cover the cut ends but not so deep that the carrots are submerged, which can lead to decay.
