Transplanting Leeks

LynnMarie_(5 SW Kansas)March 6, 2013

Hi all,

I have a quick question.

What temperatures do I need before I can transplant my Leeks seedlings outdoors? Right now they are under fluorescent lights in my basement at about 65-70 degrees. Everything I have found on leeks says they are cold hardy, but is talking about early winter rather than early spring. Are the seedlings cold hardy? Here in SW Kansas we have cool days(40-60*) and the nights are still falling below freezing, but just barely. Like around 25-30*. Is that good enough if they are hardened off? Or do I need to wait until all danger of frost is past?

I appreciate any guidance you can give me.

Cornell says to set them out around your last frost date, but I've set mine out a couple of weeks before when growing summer leeks. The rub is that if the seedlings get enough chilling, they will be triggered to bloom. In the past when I've had overwintered leeks bloom, I let them do their thing until they produced seeds.

Okay, sounds like I better practice some patience. Practice makes perfect, right?? I hope I get the hang of it soon.

Thank you Planatus

Even very young leek or welsh bunching onions (green onions) do fine here all the way through our mild socal winter. Our light frosts don't phase them in the slightest, but We don't get much under 30f.

You can direct sow outside in March in the UK although I sow 1st March in pots in the cold greenhouse because they usually follow my broad beans at my allotment and have to wait till June before I have a space to transplant them....but this is due to space and convenience, not chill or frost issues.

I am going to go for it this week. The lows won't be too low (29-35ish) and I think I can safely plant the leeks, onions, spinach and lettuce.

Oh Yeah--and my Asparagus and Rhubarb! I almost forgot :P
