I was just watching the Marvel movie Guardians of the Galaxy (great, fun movie, by the way!), and I couldn't help but notice that the tree character Groot spontaneously grows lots of extra stuff as needed throughout the movie, and I wondered how he could do that. And then I realized what a great ad this would make for Miracle Gro!
The ad for Miracle Gro could show scenes from the film where Groot grows lots of extra sinews, etc., and the announcer asks: "How does Groot grow so much so quickly? He uses Miracle Gro!" Then they could claim that Miracle Gro was originally Miracle Groot, but they shortened the name.
Then, as a tag, we could see the little sapling of Groot after he sacrificed himself to save the others, and the announcer could say: "To grow a miracle Groot, use Miracle Gro!" (Or something like that.)
