the decomposing wood chips and srump parts will tend to suck nitrogen out
of the soil in and around the hole. might be best if you removed it all
first. you can go ahead and fill the hole with soil, but test it regularly
(3-4 times a season) and ad bloodmeal or other nitrogen adding amendment.

I had three tree stumps ground in my lawn. How much of this ground
material can I leave in the hole before adding dirt ? I need to bring
the hole up to lawn level.
Also how long should I wait before adding dirt ?
