Whenever people think about growing food, they think about the typical process. This includes planting seeds, waiting for those seeds to grow, and then picking the food once it is done. Then we eat the food and then toss away any inedible scraps. However, those scraps that we cannot eat are still things that can help regrow the food.
It’s a perfect cycle and can make sure that nothing is wasted. One of the easiest projects is to regrow romaine lettuce from scraps. Plus, instead of purchasing new heads of romaine lettuce at the market, you can have your own homegrown lettuce.
All it takes is a bit of water and time, and you can guarantee that your food is organic because you are growing it right in your own home. What could be better or healthier than this? Let’s look a bit deeper into this.

Why Do Plants Grow From Cuttings?
Cutting is a policy where a portion of a healthy plant is placed in an environment that stimulates natural growth. If able to grow correctly, a cutting is identical to the regular plant that it grew from. Plus, this also allows for a plant to grow much faster than if you were growing it from a seed.
Growing from cuttings has been around for quite a long time, as plants are asexual and can reproduce independently. Once you cut into a plant, the cuttings start a process called adventitious root formation, which is a wound response. While the plant begins to heal, new roots are formed and start to help the cutting plant grow in the area.
How To Prepare Your Romaine Lettuce?
To regrow romaine lettuce from scraps, you need to buy a head of lettuce and make sure that the plant roots are intact. Slice the leaves off the lettuce, as these are typically the edible parts, and use them as you wish. Afterward, you should have the stem of the plant and possibly a 2-inch base.
Regrowing a plant depends on the stem of the plant and the vegetative buds inside the stem. Those buds will eventually cause new leaves to grow again, so you should do your best only to remove the leaves and keep the stem intact.
Starting To Regrow Your Lettuce
You should then put that stem inside a jar, cup, or bowl with the cut side facing up. It doesn’t matter what type of container the lettuce goes into, but it should be large enough to hold some water. The container should also be open and only partially full of water to prevent water from completely covering the lettuce cutting.
The open container helps prevent molding and rotting of the lettuce head, while only a light coating of water ensures that the lettuce is not overwatered. You can also use toothpicks to keep the lettuce head stable, just in case it isn’t standing up on its own.
The water should cover the stem about halfway, and then you can place the lettuce into the sun. The container shouldn’t be set into full sunlight to avoid the lettuce being burned and wilted. However, having a fair amount of sunlight ensures that the leaves taste good and that any mold is removed.
How To Care For Your Growing Lettuce?
Once you place your plant in the sunlight, you only need to change the water every day and give the plant plenty of water. You just need to keep an eye on your growing lettuce and make sure that no mold develops. If it does, then simply toss out the stem and repeat the process with a new head of lettuce.
Once you keep an eye on it, you should be able to see the little leaf shoots start to grow. Your lettuce’s regrowth should happen quickly, as the buds begin to sprout within 1-2 weeks. If they don’t grow, then you should toss the lettuce head and try again.
After 12 days, you should be able to have some form of growth and should be able to harvest them. A 10 or 12-day growth for lettuce is a pretty good haul, and you won’t get too much more than that. Just harvest those leaves and get new life from your old lettuce.
The Limitations of Regrowing Lettuce
Much like the sequels of popular movies, the regrown lettuce can never be quite as good as what it came from. Water doesn’t have the nutrients that soil and fertilizer do, so that the leaves that grow are going to be smaller and a bit more bitter than your typical lettuce leaves. Additionally, it grows fewer leaves than a full head of lettuce.
Plus, some lettuce heads simply won’t grow. Whether the lettuce doesn’t have as many plant buds or mold sets in before growth can happen, not all of your romaine lettuce roots are going to bring about new life.
You also won’t get a lot of bang for your buck, as a regrown head of lettuce isn’t going to produce as much as a new one. But with the leaves they do produce, you should be able to have a few meals. After the lettuce is entirely regrown, you need to put the head in the compost, as those leaves are all you can get.
Why Would You Regrow Lettuce?
For starters, regrowing lettuce in water is certainly fun. Especially if you have young kids who want to learn more about the environment. It’s a very cost-effective project that can teach them about sustainability and the cycle of life. You can show your kids how food can be regrown, and maybe you can learn a thing or two about the sciences as you keep working.
Additionally, if you don’t have compost or another sustainable method of getting rid of organic food scraps, regrowing can be a perfect way to reuse food. A good head of lettuce can get you some good leaves the second time around.
What Other Plants Can Be Regrown In Water?
It’s not just romaine lettuce that you can regrow from scraps and stems. Various other vegetables and herbs can be grown the same way, as long as you prepare them properly and then place them in water.
You can regrow second helpings of green onions, leeks, cilantro, pineapple, ginger, and even potatoes. You can also regrow plants in the Allium family (or plants with bulbs), and they can regenerate from scraps. Roots and tubers can also be used to regrow second helpings, and it’s an excellent way to have a bit of green in your home.
Give Growing Your Own Food A Try
Whether you use only romaine lettuce, or experiment with different types of plants, growing your own plants is a fun project. If you have a black thumb and can’t seem to grow in a plant even in the best soil conditions, then re-growing plants in water can be a perfect way to prove that you can produce something!
You won’t be receiving a lot of saved money, as regrowing lettuce from a root gets you a bit of a diminishing return each time. However, even a little saved money can add up over a long period of time, and it can also stretch your food stores out a bit.
If you are using a lot of lettuce and have plenty of inedible stems lying around, then you can stop throwing those items away and regrow them. That can undoubtedly stop any guilt about tossing those items because you can instead use them.
Give growing your own food a try and try to get a second batch of lettuce or green onions by placing the roots in water. Barring a few false starts and problems with mold, it’s a straightforward thing to do. It can undoubtedly give you some good food in return!
