Before you toss grass seed onto those bare spots, soak it in a bucket overnight with some beer! The beer helps pre-germinate the seeds so they'll sprout faster. | Spring lawn home remedies | Living the Country Life | http://www.livingthecountrylife.com/gardening/spring-lawn-care-home-remedies/
Mix grass seed in with potting soil. Fill up a nylon. Tie into segments with string to make a 'caterpillar." Soak in water till saturated. Then let the kids spray it with water every day after and watch it grow. When the grass gets "too long" let the kids give it a "haircut."
