Why Regrow Celery and Lettuce Scraps?


Tossing out leftover celery and lettuce scraps can feel like a waste, especially when you consider the effort and resources that go into growing them. Even if you purchased your celery, or romaine lettuce from a grocery store, you still can regrow them and enjoy another round of stalks and leaves! Not only does this help reduce food waste, but it also allows you to save money and enjoy the satisfaction of growing your own food. Let's regrow these scraps and enjoy a long lasting supply of fresh greens right at home!

How Does Regrowing Scraps Work?


The regrowing process may seem like magic, but it's actually quite simple and logical. When you cut off the base of a celery or lettuce head and place it in water, it has the ability to regenerate its roots and grow into a new plant. This is possible because these vegetables belong to a group of plants known as regenerative vegetables.

Regenerative vegetables have the unique ability to regrow from their own scraps due to their meristematic tissue, which makes them capable of producing new growth; essentially, they are the "growth zones" of a plant. By harnessing this natural process, you can turn what would have been waste into a new supply of fresh greens.




Step-by-Step Guide to Regrowing Celery and Lettuce Scraps


Regrowing scraps is a straightforward process that requires minimal effort and materials. Here's a step-by-step guide to help you get started:

  • Selecting the Right Scraps: Choose a celery bunch with fresh and healthy-looking stalks. Cut off the base of the celery, ensuring that you have about 2 inches of the stalk attached to it. You can do the same with Romaine lettuce heads.

  • Preparing the Container: Take a small container, such as a glass or a jar, and fill it with about an inch of water. The container should be wide enough to accommodate the plant base without it toppling over.

  • Placing the Scraps: Place the celery/lettuce base, root side down, into the container with water. Make sure that the bottom of the base is submerged, while the top remains above the waterline.

  • Positioning the Container: Find a spot where your plant base can receive indirect sunlight. Avoid placing it in direct sunlight as it may cause the water to evaporate quickly.

  • Changing the Water: Every few days, check the water level and replace it if it starts to look murky. Keeping the water clean helps prevent the growth of bacteria that could harm the regrowth process.

  • Patience and Growth: In about a couple of days, you'll see new leaves emerging from the center of the base. After about a week to 10 days you'll notice tiny roots sprouting from the base of the celery and lettuce. At this point, you can transfer the sprouting plants to a pot with soil, allowing it to continue growing.

Remember to be patient and give your lettuce and celery the time it needs to regrow.

With proper care and attention, you'll soon have thriving plants ready for harvest, that would have otherwise been tossed out - all for free!

Tips for Successful Regrowth

While regrowing celery and lettuce scraps is relatively simple, there are a few tips that can help improve your success rate:

  • Choose Fresh and Healthy Scraps: Select scraps that are free from rot or mold. Fresh scraps have a higher chance of regrowing successfully.


  • Maintain Adequate Water Levels: Ensure that the base of your scraps is always in contact with water but avoid submerging the leaves. Adding water regularly and keeping it clean prevents bacterial growth.

  • Provide Indirect Sunlight: Place your regrowing scraps in a location that receives indirect sunlight. This helps stimulate growth without drying out the scraps or causing excessive evaporation.

    Be Patient: Regrowth takes time, so be patient and allow your scraps to develop roots and new leaves before transplanting them into soil. Either place in a pot for container gardening on a porch, or directly into a prepared garden bed.

Other Vegetables and Herbs That Can Be Regrown from Scraps

Celery and lettuce aren't the only vegetables that can be regrown from scraps. Here are a few other popular options:


  • Green Onions: Place the root end of green onions in water, and soon, you'll have a fresh supply of green onion shoots.

  • Carrots: Carrot tops can be placed in water to regrow leafy greens that can be used in salads or as a garnish.

  • Herbs: Many herbs, such as basil, mint, and cilantro, can be propagated by placing cuttings in water until new roots develop.


Creative Ways to Use Regrown Celery and Lettuce

Once you've successfully regrown your celery and lettuce, the possibilities are endless. Here are a few creative ways to use your homegrown produce:

  • Fresh Salads: Harvest your regrown celery and lettuce, and toss them into a vibrant salad filled with other seasonal vegetables.

  • Juices and Smoothies: Blend your fresh celery and lettuce into nutritious juices and smoothies for a refreshing and healthy treat.

  • Sandwich Toppings: Add crisp, regrown lettuce to your favorite sandwiches for an extra crunch and burst of flavor.

  • Stir-Fries and Soups: Incorporate your regrown celery into stir-fries and soups for added texture and flavor.




    One year I had grown so much celery from one plant scrap, I had to preserve it all by dehydrating it.
