They are last year's seed so germination may be low. They don't have a long shelf life. My Megaton leeks and onions came up in 4-7 days. You only planted 6 leek seeds? There's probably 250 in that packet so plant some more.... If you go to the allium forum there is a seed starting thread I made for my alliums, with good advice I got and pictures of my seedlings.

I've done germination tests on leek seeds that I saved myself. At 3 years old I got 70-75% germination at about the 2 week mark. Not great but still good. I doubt the seeds you have are bad, especially since you are just barely starting to see sprouts. Give them a few more days and some others should follow.

Agree with Peter that you should plant more than 6 seeds. Start 50 seeds and transplant them around the border of your garden.

The last week of Feb. I sowed those same King Richard leeks which I too got on sale at Johnny's. I got almost 90% germination, and they are now anywhere from 1" - 3" tall. I treated them the same as any seed I've sown this year... sown in cell flats filled with seed starter mix, and left on top of the lights until germination, then placed under.

I'm wrong actually they should be this year's leeks, just on sale because they won't sell them next year.

well thanks for the replies. I did however put 3 or 4 seeds in each jiffy pod. Suppose I should wait a few days longer

If you look it up, standard germination time is quoted as 10-14 days. That's been my experience. Perhaps if it's warmer, they'd come up sooner. But I'd just wait a while more.

No heat mat for leeks or onions. They don't want it.

Yes, that's a good point. If the pots are sitting on the heating pad, the soil temp will be a lot higher than the air temp over the pots.
