I'm afraid it wasn't Miracle Grow that ruined your garden. I'm sure your English teacher would agree.....
Salts cause lock out. PH can cause lock out. Miracle Grow is not going to lock up a plant. That is just retarded. They have been in business longer than you have been alive. Come out of the back woods, and try it. They don't have any fancy designer labels, or midievil, gothic artwork on their web page, no wizards with crystal balls, or dragons breathing fire down on tomatoes....
They also do not have ridiculous prices for fertilizer. They even offer an organic line, so you can't argue that point either.
Posters that decry that MG sucks are usually ill informed, naive, and inexperienced. They more than likely tried MG soil for their very first grow and through inexperience, missed a watering, or overwatered and rather than place blame where it belongs, they blame one of the best selling lines of fertilizers and soils.
People don't keep buying shit over and over when it kills plants or doesn't work. When you are in school today, ask your Economics teacher about it.
p.s. DON'T skip spelling class today and pull those damn britches up and tighten that fucking belt.....
