Leave about two inches of green above the bulb and roots and transfer them to a glass of cool tap water. Place it in a very sunny area and change out the water every day for the first three to five days, and then every other day after that. Your green onions will grow back astonishingly fast! Expect to see about a centimeter of growth every two days. Prune the roots if they start to overfill the container. You can trim as needed for your recipes and enjoy fresh garnish to all your dishes without having to run to the store.
Celery and Bok Choy
For both of these vegetables, cut off about a two-inch section above the roots and place in a shallow dish of water. You can use toothpicks to hold the cutting in place. Leaves will start to sprout from the center of your cutting in a few days, followed by a stalk of fresh bok choy or celery. If you’re not going to replant in soil, you’ll want to trim down your plant regularly. This is also an effective way of regrowing salad greens like romaine lettuce!
It’s important to use fresh, green stems when regrowing herbs. Cuttings that have started to go brown around the base will have trouble sprouting roots. The best herbs for beginners to regrow include basil, mint, lemon balm, oregano and stevia. More difficult, woody herbs like rosemary, sage, oregano and thyme take a bit more effort and skill to propagate effectively. Once you have your green cuttings, clip away any leaves growing on the bottom two inches of the stems and place them in a glass of water in a sunny area of your home. Trimming the plant regularly will encourage the growth of new leaves.
Get creative with all the different kitchen cuttings you can regrow in your own home with supplies you already have on hand. Use decorative jars to transform your snipping collection into a focal point of your kitchen, and save up new cuttings from the recipes you cook to help your garden grow.
