After drilling and applying this product, should I cover the stump or just the rain soak in?

Hi,thank you for the inquiry regarding out 16-oz Stump Remover.The product is ,to be applied per the label directions. Drill several 1-inch holes up to 12 inches deep into stump. Then into the side of the stump, approximately 3 to 4 inches from the top, drill a 1-inch hole slanting down to connect with the bottom of the center hole. Pour approximately 4 oz of Spectracide Stump Remover Granules into each hole. Then fill with hot water to dissolve the granules. Continue to add water to the holes for several days to ensure Spectracide Stump Remover Granules dissolve completely. Allow the decomposition process to take place for four to six weeks before removing the stump..
