Should we put a flat stone in the hole to restrain the pivot of the plant?

Put a flat rock at the bottom of the planting hole from could be a good intention, because what we are looking for with truffle trees is spreading root system. But it causes discomfort to the roots of the oak that has a taproot system. It was found on the ground, the pivot skirted the flat stone to plunge further; this practice is useless!
