Now I don't know about store bought Osmocote, but I use Osmocote Pro, which is designed for professional nurseries. The blend is 17+11+10+2MgO+TE and is a 2nd generation release fert. This means that it releases a larger percentage of Nitrogen in the beginning, and then shifts to greater P/K later. It is the top of the line fertilizer, and more than likely you will never see it in a store.
Put it in the container/ground and FORGET it.

That sounds like a great pic.... I chuckled just imagining it.
