Cockadoodle DOO Super-Premium Organic Lawn & Garden Fertilizer seems very expensive compared to chemical fertilizers. Why is that?

At a glance, this would appear to be true. A 40-lb bag of Cockadoodle DOO Super-Premium Organic Lawn & Garden Fertilizer that costs (suggested retail) $29.95 at professional independent garden centers seems expensive when compared to much cheaper chemicals that sell for under $10.00 at hardware stores. Here's the difference: just a little bit of Cockadoodle DOO goes a long way! It continuously feeds your grass and plants for up to 90 days, delivering an even-balanced and nutritional feed while replacing the organic micro organisms instantly back into the soil. Chemical fertilizers only feed for 10 to 14 days on average, while sterilizing and robbing the soil of all the natural trace elements and micro organisms. You will have to buy MORE bags of the chemical fertilizer to have the same 90 days of effect Cockadoodle DOO provides.  more
