This is an update to my previous ramblings on a source for CSM. I just talked with the most pleasant salesperson about ordering CSM. A company called D&L Growers Supply in Lyola Pa has 5 lb buckets for $41.75 plus UPS shipping. I also purchased another product called "Ferric 3" ??? that is primarily chelated iron for $37.75 / 5 lbs. Their number is 717 656 0809 or 800 732 3509. Ask for Cheryl. Lyndle Schenck
