Hello. I had a soil report done last fall. They are recommending three fertilizer types: 12-0-42 or 5-0-15 or 0.7-0-2. I did a quick search online hoping to find a retail location to find it. That wasn't very helpful I am willing to visit Home Depot, Lowes or anywhere else I need to but wondered if what I'm looking for exists in this formulation or where might be the best place to get this. I haven't done this before. I appreciate any help you can give me!
