If you cut the leek about 25mm or so above the roots (leaving the bulb bit) it can be replanted. Haven't tried it myself but a few people have said it works.

How can I tell when my leeks are ready to harvest? Most have pods which haven't opened as yet.

Most leeks mature 100 to 120 days after sowing the seeds, but a few varieties mature in as few as 60 days. Begin the harvest when the stalks are about an inch across. Depending upon your climate, you could be harvesting leek plants from late summer until early spring. Picking leek plants that mature at different times of the year lets you extend the harvest.

Which variety of leek are perennial?
18 Oct 14, Chris (Australia - temperate climate)
Any type which produces offsets (baby plants growing off the base of the stem) potentially perennial. You leave or transplant any offsets when you harvest the main plant. Allium ampeloprasum var. ampeloprasum is a perennial or multiplying variety.

WHAT DOES IT MEAN TO 'BLANCH' THE STEM OR PLANT?
13 Jun 14, Andrew (Australia - temperate climate)
It means to exclude light from the stem. That is what creates the white, tightly packed section of the leek, which is the bit we like to cook with. There are two main ways to achieve this: 1. As the plant grows, pack soil around the stem; or 2. Plant seeds or seedlings in a trench (about 10cm deep) and as the plant grows fill in the trench. Hope this helps.

I tried sawing the seeds in trays, but no seedlings emerged, even after 3 weeks. I tried many times, but none was a success. Not sure what I am doing wrong. I live in Melbourne, and I have raised beds, prepared with good potting mix.
