As for the statement by
@Stone that nothing will grow where the stump was ground, well

Here is a photo of the area where a large tree was removed and the stump was professionally ground down. I call it my 'mini-woodland' garden.
Here is my DIY attempt to cover two stumps which had not been ground:
and the same 2 boxes at one year:
As you can see, while I agree with Stone's dislike of turf grass, each person must do what they think is right for their own yard and, in some cases, must adhere to the regulations of their community. The original poster is only trying to decide by which method the stumps will be ground - professional or DIY. Thank you for visiting my front garden.
