No, but how long are you holding them for?? I bought one batch late last fall and went ahead and potted them up until I could plant them a few weeks ago. I still only held them in the original pots for about a week.

The last batch I got the first of Mar I held for 8 days without a problem either.

I bought ones from Sequoia and held them in the garage for about two months before potting and planting them. I really didn't notice the difference between the two soils.

Most likely the roots are rootbound in the pot and need to be repotted or planted soon.
