The best and most amazing thing about lettuce, besides eating the tender green leaves, is the amazing fact that if the bottom of the stump is saved and placed in water, regeneration and new growth will occur. Above is a photograph of three romaine ‘stumps’ in various levels of regrowth. All I did to achieve this miracle was place each piece in a half inch of water, check the water level daily, and marvel as the stump began to grow anew.
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. The setting for the lettuce doesn’t look nice, but it creates the perfect environment for regrowing leafy greens…cool and bright all day. Experiment yourself with this method 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 grow.
Important Tip: Romaine Lettuce is one type of produce easy to find in the organic form. Often packaged as three hearts of romaine, spend just a dollar or two more, and you have salad free from any unnecessary pesticides.
