planting grass over ground up stump
We cut down a 70 year old silver maple in November. Huge limbs had been splitting and we decided the tree was dangerous. The tree removal crew left a big pile of ground up wood chips from the stump for me--I wanted those for mulch. I've been gradually reducing the pile of chips and putting the chips in borders for mulch. How much should I leave in the mound? I know the roots and chips underneath will be decaying over the coming years and the ground will settle. How much settling should I expect for a big tree like this? Will it be okay to plant grass over the area this spring or should I wait until September? The whole yard needs renovation. Nothing but moss and violets grew under the tree. We've planted a sugar maple but it's going to be a while before we have shade again.
