How long can i leave leeks in the ground and still be edible ?

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.

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?

G'day Heidi, I also have trouble growing Leeks & I also want to know why they don't like being on their own. I'll be keen to know what people suggest to you & I'll try it myself. Mate, I just wanted to let you know your not on your own !!!!!!

if i prune leeks back will they regrow or if i plant the bulb will i get more leeks

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.

Maybe water was caught down between the leaves and it just went rotten.
