How to Regrow Lettuce From the Stem

If you hate wasting food and can’t bear to throw away any kitchen scraps – like a lettuce head – I’m happy to report that my mom experimented with regrowing lettuce from the stem.


This is the perfect solution if you want to eat local, organic produce. What’s more local than your own kitchen window sill?  Plus, it’s more affordable than going to your neighbourhood farmer’s market for fresh produce.  In fact, the only thing it’ll cost you is a little bit of water and time. 

You won’t get a huge harvest, but you should get enough to toss a salad together or at least add some greens to your sandwich.  

Here’s what you need:

  • Leftover head of lettuce
  • Small container 
  • Tap Water

We used romaine lettuce, but you can also try with other types like iceberg.  My dad is even trying with bok choy! 

Place your lettuce on a windowsill that gets a few hours of sunlight each day.  Within a day or so, we saw little green leaves starting to grow.  Don’t forget to change its water every 1-2 days. 

Apparently, your newly grown lettuce will be ready to harvest in 10-12 days.  It won’t grow any bigger after this time period and will actually become very bitter the longer you leave it.  So grab a pair of scissors and eat your harvest while you can.  

That’s it!  Easy, right?

Have you tried regrowing lettuce from scraps?  Let me know!
