Why Regrow Romaine Lettuce?
The number one reason why I do it is because it’s fun. I like to look at my lettuce all smug and think “other people would have thrown you out, but not me. Nope!”. But it is always handy to have extra lettuce in the house.
It is also cost effective to regrow your kitchen scraps instead of throwing them out. Buy a few heads of lettuce and keep them growing year-round taking only what you need for each meal.
How to Regrow Romaine Lettuce
Okay, here we are at the point you really want to know! Save the end from your lettuce and put into a little water (about a half inch). Change out the water every day. It is very important to change out the water every day or your run the risk of the outer edges getting soggy.
The lettuce will grow back incredibly quick.The one on the left I cut today. The middle one yesterday and the one on the right, two days before. You can see how much it grows in just three days!!
Regrowing Romaine Lettuce in Soil
I have had a lot of questions about the growing process. Unlike the green onions which I leave growing in water forever, lettuce does better when transplanted into soil after the roots have begun to develop. Romaine can be regrown in water only but I find the plant starts to suffer after a few weeks. The small leaves develop but it never reaches it’s full size.
I use tap water. Just my plain old municipal water and they grow just fine. I know that my city does not fluoridate their water so I am not sure how that would play into the growing process. If you are worried about your water quality then a bottled water is best.
The quality of water is bound to make a difference to the speed of growth of your lettuce. Well water tends to have more minerals intact and results in faster regrowth.
Organic or Not
So here is my dirty secret, I do not buy organic lettuce. I should. I know I should! I know some veggies that are not organic are treated so that they do not start to regrow or produce roots after harvest. This has not been a problem for me growing lettuce. If you find that you are unable to get your lettuce to root then try an organic batch next time.
Regrowing Other Kitchen Scraps
Green onions are ridiculously easy to regrow. I buy a small pack (of 4) about once per and keep them on my windowsill. They continue to grow at an alarming speed. The green onions growing in my window have been growing successfully for almost two years now!
