Stump Grinding + Returf ?

I mentioned in another post we are having some conifers removed . The trunks will be about 12" Diameter. The tree guys are also grinding the stumps out . Now having zero knowledge on stump grinding... I presume they grind the stump to say 4" below the surface ? Will this be ok for levelling with top soil and re turfing next spring

 

When we've had stumps ground, the machine has gone down a good 8 inches - probably more

The process is a brutal and does make a fair sized hole.

I used the chipping/soil mix to fill in the hole but over time the wood has rotted and the soil level has dropped. I also have mushrooms/toadstools growing where the tree once was. Not sure if this is coincidence or due to the wood in the soil. I reseeded as soon as the hole was filled

To avoid this I would use new topsoil and move the spoil from the holes to one side for the wood to rot down for a year or so.

 

Thanks Andrew, the guy who is removing the trees wil also returf next spring. I'll make sure he grinds the stumps down to the best depth for turfing.

 

Just had the conifers removed and the stumps ground down before we went on holiday . As you say the stump grinding is a brutal process . It basically batters the stumps into hundreds of pieces. As soon as the tree surgeon saw the conifers , he said red spider mites was the problem . We have seen the tiny webs on the conifers for years , not knowing what they were . This very hot and dry summer must have put them in overdrive. By the time we had the trees removed the growth was 50% dead.
