The best and most amazing thing about lettuce, besides eating it, is that if the stump is intact it will regenerate and regrow new shoots for a second harvest. Above is a photograph of three romaine “stumps” in various levels of regrowth. All I did was put each stump in a half inch of water, check the level daily, and wait for tender new growth.
I am growing the romaine in a basement window well, and that explains the VERY dirty window in the photo as it is below ground level and gets a lot of run-off from the sides of the house and mud spatters from ground. The setting for the lettuce doesn’t look very nice, but it is the perfect environment for regrowing leafy greens…cool and bright all day. Give it a try the next time you have a head of lettuce with the stem still intact. You have nothing to lose and a free harvest of lettuce to gain.
Important Tip: Romaine Lettuce is one type of produce that is easy to find in the organic form. It is often packaged as three heart of romaine and it pays to spend just a dollar or two more and have your salad free from any unnecessary pesticides.
