Not only do they work as well, the green up will last longer. Organic fertilizers feed the soil by enriching it with nutrients and organic matter. When the plant calls for nutrition it sends a signal to the soil and the soil delivers the nutrients to the plant. This is the way nature intended it to work. You have to be a little patient – it will take about 7 days to see the results of the fertilizer application (green up). However, it will continue to feed the grass for 8 to 10 weeks. The roots will be deeper and stronger, the color will last longer, the soil will be built up and the nutritional value will be restored. All this with fewer applications each season. Why does it take longer for organic fertilizer to work than synthetic chemical fertilizers? What is the difference? Chemical fertilizers feed the plant, not the soil. They provide a highly concentrated amount of nitrogen to the plant resulting in instant green up (2 to 3 days), but the effectivenes
