What would make basil seedlings not grow?
I'm confused. My basil seedlings came up and then stopped growing. They've been the size of the head of a nail for weeks, even though they seem to be alive.
I used pro-mix with 1/10 worm casings (the pro-mix is what I normally use for sunflower sprouts in the winter -- not for seedlings, but it was all I had on hand).
They've spent some time under lights, some in sunny window, some on sunny porch.
THey've been warm.
They've traveled to 3 states, but all my seedlings do that every year.
Also, the seeds were old (2010 and 2011) and germination was extremely low.
Should I just start over with some good potting mix and toss these?
Also, if anyone can tell me why this may have happened, maybe I can avoid it next year. I may have to end up buying a dozen basil plants because the pesto must be made!
