To those that work around me, I am not a fan of Miracle Gro (despite the fact that we sell it). I don't believe in pre mixed fertilizers unless they are all natural like TerraCycle. Let it be known that you do not always know what they put in those fertilizers. Some change the PHD of your soil and remember what you put in your soil always gets recycled back to you.
I like Terra Cycle because not only is their fertilizer 'worm poop' but they also buy back all the recycled bottles (no matter what the size) and are the only company known to do that (also accepting old recycled bottles from the public and drop offs).
This is my own opinion and by no means reflects the company I work for. We can't always stand by all the products that companies sell but you can educate people, so that they can form their own opinions.
