G'day !! I planted my Leek seedlings at the start of October '16, it is now January '17 and my leeks are still thin and they look like spring onions. What have I done wrong and how can I grow fat leeks ? I've followed all the steps on the label that came with my punnet of Leek seedlings, please help I would honestly appreciate it. Thank you .... " Cheers "

Hi kathy, Same problem, I'm in coastal southern NSW and after 6 months... I had lovely Leek Flowers & gave up. About to replant in late Feb more leeks, hopefully will not fail again.

Hi karen and kathy, Leeks need to be pumped with plenty of organic fertilizer Blood n bone, chook/cow manure etc ,water well, also they love Magnesium (epsom salts ) apply via a water can or direct then water well

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 !!!!!!
