Johnny: The peat pellets will pose a problem in that they are intended to be planted directly into the ground with out seperating the peat from the roots. You do not have to hurry to transplant your seedlings, wait until the weather warms up. Untangle the roots from the peat and cut the tap root leaving idealy four or more lateral roots around the trunk of your seedling. Plant into a four inch pot and start feeding when new growth is astablished. Sounds like you are having fun. I personally start seeds every year. This year I have started J-black pine, bald cypress, celtis, coark oak, peach, J-maple.
Good Growing.........ripsgreentree
