Big Bluestem Seedlings
Back in January, I planted seeds of big bluestem in one of those plastic pot saucers filled about 3 inches deep with potting soil (the saucer is approx 9 or 10 inches in diameter). I now have one giant plug of big bluestem seedlings that are about 3 inches tall. My original plan calls for me to now divide the entire mass into smaller plugs, repot, and set them out in an unheated greenhouse until early fall when I will transplant them into my garden. I've noticed that some of the blades are turning reddish tan, similar to BBS's fall color. Is this normal? Do you think I ought to divide and transplant these now directly into the garden?
