About Top Dressing with Sand

According to the Institute of Food and Agriculture at the University of Florida, top dressing home lawns with sand is more harmful than helpful. Experts agree that sand should only be used on a lawn to level low areas, cover exposed tree roots and to . Even in those cases, it is recommended that you top dress with a rich, fine compost instead of sand.

Sand particles cannot retain any nutrients, so applying a layer of sand year after year to lawns actually causes lawns to lose their fertility.

Clay soil particles are flat and card-like. They lay on top of one another making water unable to penetrate them. When you add larger, heavier sand particles to this scenario, it weighs down the clay particles, making them even more impenetrable by water and nutrients.
