Let's be fair. Monsanto, being a corporation, wants to maximize its profits for its shareholders. So it looks at ways to increase its share of the market, and already knows how to use advertising and brand name to its advantage. If anyone has actually used Miracle Grow's best potting mix, they know it comes with rocks, lots of bark, some kind of super dried crap that never absorbs water, has ferts in it that seeds don't need (ad nauseum) but every hardware store in the US sells it. Try finding a local store that sells Fox Farm, Ferti-Lome or other decent mixes.
Consumers - you, me, our families and friends will determine the outcome. Keep walking in an Ace, True-Value, Do-It-Best, Walmart, Lowe's, Home Depot and buy their potting mix and Monsanto grows bigger and strong. Drive up the road to Ed's Seed and Feed and buy good mix - Monsanto doesn't make as much.
