sources for professional potting mixes
I've been trying to get a hold of one of the following mixes for some tree seedlings I'm starting that has been recommended on another forum, but am hitting a brick wall.
I'm in Columbia, MD between Baltimore and Washington, DC. Local or online sources are OK.
Looking for either Metro Mix 852 or Fafard 51.
Most "garden centers" around here answer with a blank stare.
Anyone got any sources?
