That's why I try to do them when they're so small; the roots don't get a chance to tangle. Have you tried the straight vermiculite yet? Even if they do get long and tangled they don't hang together in such a light medium. I love it. I still have seedlings holding in their w/s containers, and some of them sprouted in March!
That's a heck of a lot of leeway in getting them out and transplanted. It's simply amazing to me that they 'keep" that long!
Now, I'm not entirely sure yet how those long holdovers are going to perform...but it's still exciting to think that the big spring transplanting rush might not have to be so crazy.
