Your member page doesn't say where you live (my pet peeve) but I'll just go ahead and assume you are listening to Howard Garrett in Dallas. He's the only guy in the country promoting dry molasses. For the life of me I don't know why. It is hard to spread and if you don't spread it all, the left over stuff in the bag turns in to a solid rock. But other than that, I have never found molasses of any kind, at any concentration, to do anything noticeable in my yard.

If you are still going to try molasses, I think you're much better off using liquid molasses at 3 ounces per 1,000 square feet, about 4 times per season. The ingredients of a 50-pound bag of dry molasses are 35 pounds of chipped corn cobs or rice hulls and 15 pounds of wet molasses. 10 pounds of wet molasses (about a gallon) costs $1.00 at your local farm and ranch co-op. You have to bring in your own container.
