05 Dec 16, John (Australia - temperate climate): In southern climates they can be left in the ground until early Spring. I hope someone from the sub-tropics sees you question and can answer better.

31 Aug 16, Heidi (Australia - temperate climate): I have always had trouble growing leeks. When I transplant them from bought seedlings, they don't thrive and fatten up. Someone suggested I leave them in clumps and this seems to work. What is the reason they don't like being on their own?

06 Apr 15, Pete (Australia - temperate climate): 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.

10 Aug 15, Brianna Mckenzie (Australia - sub-tropical climate): 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.
