Then add in roughly eight parts of dry sand to one part of seed, and mix well. (For example: 8 cups sand to 1 cup seed.) Always make sure that your sand is dry, especially if it has been stored outdoors. Wet sand has a tendency to clump and can cause your seed to be applied unevenly. If possible, starting with new sand helps prevent contamination.
