Trees, Shrubs and Conifers: Planting hole / stump grindings question, 1 by claypa

So now the hole is full of ground up maple roots and soil. I really don't have any place else to put the fill, so I just pushed it all back in the hole. I figure I can use my compost pile to add to it as it settles, and more soil if need be.

I plan to throw a bunch of nitrogen fertilizer on top and water it in a little. Any ideas on when I could plant some shrubs in this hole? The tree was/is dead, no suckers or anything. The roots were all dry and brittle. Any advice or suggestions are greatly appreciated, thanks.
