what is the fertilizer (N, P, K) composition of these, e.g. 5-10-15?

(No, it’s not 10-15-15, as another answer says). It is 15-5-10. I have a recent package right in front of me, so I’m relaying this directly from the “source.”

Is this a 10-10-10 fertilizer?

10-10-10 is considered an all-purpose, balanced fertilizer that you can use for all kinds of plants and situations. The numbers 10-10-10 represent the amounts of Nitrogen (N), Phosphorus(P) and Potassium(K) - or as they're commonly known, NPK. That means there's about a full ten percent each for all three nutrients which are considered primary ingredients needed by plants to survive! Fertilizer grades are made by mixing two or more nutrient sources together to form a blend, that is why they are called "mixed fertilizers."

Just a couple questions... how do i place these spikes around the trees and shrubs, how far away? one spike each? what type of fertilizer is it? safe

The pictures and instructions depict placing them at the drip line of the tree, so about where the bulk of the branches extend. It a circular pattern so like 6 for a bigger tree. In my case about 6 ft away from the trunk, I put 2 on each side of my smaller trees 45 degrees apart due to sidewalk and street restraint etc...
