Regrow Leeks – from root ends!

This winter I have taken leeks to regrow from root ends! Normally, these scraps go to the compost heap. I have had great success in regrowing spring onions from their root ends and some promising growth from celery scraps too! So I am hoping for a similar adventure with the leeks this season.

Leeks are so delicious in winter as they are in season! I love cooking with them as they lend a sweet taste once lightly sauteed. Leeks form the base of many of my sauces, so instead of using onions I use leeks. On this occasion therefore, I took these two leeks that I bought and sliced the green leaves to cook with.

How to regrow leeks from root ends

I left the bottom white root ends to try to regrow the leeks.

Then I placed these two ends in a shallow bowl of water on the windowsill. The water in the bowl gets changed every 2-3 days to be refreshed. These root ends are great to watch when you are washing the dishes and a pretty addition to the windowsill in winter!

After a couple of weeks, there is obvious growth as you can see in the picture below. The leeks have begun to regrow, with their green leaves growing upwards. In the water, you can see longer roots appearing on the bottom ends of the leeks.

This is so exciting that I am now considering planting these leeks in compost. As these leeks are developing longer roots, it is likely they will continue to thrive. I am hoping that they will grow stronger so that I can keep cutting the green tops for my cooking. This is what I do with my spring onions and they have been regrowing very well.

My next vegetable is probably going to be the onions as I use lots in my cooking. I have seen that this could work really well as shown in this regrowing onions post.

Inspired to regrow leeks, spring onions or other vegetables from root ends? Have a go, you have nothing to lose and it is fun watching them regrow! A great way to begin indoor windowsill gardening and also reducing waste!

  1. Hi
    I’ve tried to do that and they grew in water really well. I then proceeded to pot them and left them on my balcony (yesterday) and now the leaves are all droopy 🙁
    Would you happen to have a clue why?

    1. Hi Raina, Did the leaves droop after they were potted up or before?
