Growing your own vegetables doesn’t have to start with seeds or seedlings — many kitchen scraps can be given a second life with a little bit of water and patience. From lettuce and celery to green onions and basil, regrowing vegetables at home is a simple, sustainable way to make the most of your produce and enjoy fresh greens year-round. With just a few easy steps, you can turn vegetable trimmings into thriving plants, reduce food waste, and enjoy the satisfaction of homegrown produce right from your kitchen window. Read on to discover how you can resprout your favourite vegetables and herbs with minimal effort!
Lettuce:
When eating your lettuce, cut the leaves off and leave about an inch or two of the bunch’s bottom. Place the stem in a bowl of water to hydrate. In about 3-7 days, your lettuce should start sprouting. When this happens, you can transplant your sprouting lettuce in soil or leave it in the bowl of water, and harvest the baby leaves for salads.
Celery
Similar to the lettuce, the celery base should be cut the same way – leave 1 – 2 inches of the base to resprout in water. The center part of the celery holds the most nutrients for producing new stalks, hence, it is important to keep it.
Fresh Basil
Select a stem that does not have a seed stalk or the crown and that is at least 8 – 10cm long. Remove all the extra leaves so that you are only left with the top two layers of leaves. Put the stem in water and change the water every two days, you will see roots starting to grow. After two weeks, take the stem out of the water, plant into a potting mix and water well.
Green Onion
Don’t discard the roots of your green onions! You can regrow or sprout them again just by placing the roots in water and setting it in a sunny spot. Replace the water every couple of days. If you’d like your onions to last longer, transplant them into a pot. Your new green onions will be harvest-ready in 7 days.
Tip: Cut green onions near the white root, be sure to leave some of the pale green portion next to the cut root (cutting right at the white part will mean a longer regrowing time).
Onions
Yes, you can regrow onion bulbs from your kitchen scraps! When slicing your onion make sure to leave about an inch from the root. Leave the piece out to dry for a day or two until the edges curl up, then place it in soil with the root side down. Cover the onion in about an inch of soil and water well. When green shoots start to appear you can harvest them like spring onions or allow them to grow into onion bulbs, which would take about 90 – 120 days until it is ready to harvest.
Regrowing vegetables from kitchen scraps is an easy and rewarding way to stretch your grocery budget, reduce waste, and enjoy fresh, homegrown produce right at your fingertips. Whether you’re sprouting lettuce, celery, green onions, or basil, you’ll be amazed at how quickly your kitchen discards can transform into vibrant new plants. This simple practice not only supports a sustainable lifestyle but also brings a bit of nature indoors, making it perfect for any home gardener, whether you have a large backyard or just a sunny windowsill. So next time you’re about to toss those vegetable scraps, give them a chance to regrow — you might just find your next salad growing right on your windowsill!
