Walrod might have had a hand in turning the Tenrou Tree from a normal tree (if you can call such a massive tree normal) into something magical that grants the blessing.

Considering how the people of Red Lizard could be killed, it's clear that they didn't have the same kind of blessing as Fairy Tail had later.
