You can regrow leek also

It's easy, simple and rewarding to regrow leek from its basal parts.  A couple of experiments show the importance of the length of the basal part cut off for a swift regrowth.  It is recommended to start the regrowth with basal parts of at least 4" (10 cm).
Interresting experiment, I think we will try it this summer. Another idea would be to use the curled growth of the cut basal part as a &quot;stylish&quot; plant, then surprise your guests that it is actually leek. <br> <br>Out of curiosity, cutting off the regrown leek at about 10cm will allow the plant to regrow anew, right? So leek could be &quot;harvested&quot; from the same plant about every month? <br> <br>Also, did you use any kind of fertiliser?
I did this experiment indoors and in our Belgian winter time. The regrown parts were not as firm as the one grown outdoors. My visiting friends are astonished indeed !<br><br>I intend to repeat the experiment in my garden to see if repetition of the regrowth is possible. I used only our local soil mixed with some compost.
The photo I posted is of a leek planted in potting soil and organic fertilizer. <br><br>Temperatures outside are between 15c&deg; at night and 32c&deg; during the day. Right now it's getting about 12 hours of direct sunlight a day.
<p>As I eat most of the white part and leeks here in the netherlands dont have that much white to begin with, it seemed a bit of a waste to do this method.<br>However, I started using the bottom say 1-1.5 cm of every leek (Yes, Frugal-Dutch) I used (even before i read yr article) and had some success as well.<br>From the perhaps 8 leek bottoms I put in the garden, 1 started to grow and has now developed a sprout of about 20 cm length and recently even a sidesprout popped out. Not sure what the plant looks like, as I started covering it up with soil and see if i can get a decent edible leek out of it.<br>My low succesrate 1/8 may well have to do with the random method of planting. I basically just put the bottomhalf in/on soil, sometimes not even covered. <br>Now I know the process works. I will probably do it in a more careful manner with next leeks.<br>Tried the same with onions, but little success (an entire onion works, no doubt about that). The top of a carrot works great as well. It does develop a lot of green, but, eventually various carrots start growing from the stump. They wont win a beauty prize but taste good</p>
Same leek 13 days old.
Fantastic. Congratulations.
<p>Works beautifully. 4 day old leek. </p>
<p>sadly most leeks available here (Netherlands) have a white part that may only be 10 cm. Regrowing it might therefore be kinda defeating the purpose: sacrificing a leek to get a new one</p>
