Blue Gramma Thatch & deer dung

Asked May 20, 2013, 2:29 PM EDT

Our Blue Gramma lawn is 3 years old. While we are gone from Colorado Springs during the winter, deer inhabit our yard. Will the piles of deer droppings damage our lawn or is it OK to leave them on the lawn? Since Blue Gramma does not spread, there are spots of dead thatch. Should we rake those up & place new seed in those areas? What is the area/diameter of the Blue Gramma plant?

The deer droppings won't hurt the lawn...but may be unsightly and could slow the growth of the grass if they are thick. Otherwise they are natural fertilizer. Blue grama is pretty much a bunch grass. The plants will form clumps (if not seeded densely and mowed like a lawn) that can eventually grow to 6-10 inches across; however, they may die out in the middle of the clump when they get that large. Yes, you can scratch up the dead areas and replant them with blue grama seed.
