I have the odd feeling that the most Mclane and Tru-Cut mowers are sold per capita in Hawaii. Any homeowner that is not mowing a weed patch has one and the majority of mowing people have reel mowers. How are the nutrient levels in the areas where the Ultimate Flora has trouble taking root? When people have actual sand in their yard, I stop trying to apply everything in 30-45 day shots, never mind a spread and forget. Rain and irrigation will leach much of what is broadcasted past the grass roots causing pollution. Now, a good practice that I follow should I be working with pure sand is to till in 6" of composted organic matter before grassing an area.
