She gave me 3 of them out of her box, that was my thinking too. Just break em up like fert cakes .... guess not lol
I use agri-form fertilizer tablets on some of my trees and they are meant for agriculture and/or trees in the ground. I wouldn't use them on a maple, but try just not crushing them up and placing on top of the soil of a young developing black pine or something. I bet it will really take off. I think by crushing you are greatly increasing the solubility, but as a whole spike it might do just fine.
back on topic, I'll say: Don't just let club members handle your trees especially when they are speaking to prospective new club members. For some reason hey'll just start cranking away on prospective, dramatic bends in your material without any regard to your plan or say flaky bark. They start showing off and cranking away. "Maybe this branch could go here or pull this one up as a a new leader"...
