A. Nothing wrong with fresh pine chippings. We provide an assortment of wood chips, fresh, at the orchard for the public. You will have no problems with it. As it is decomposing make sure you give the soil some extra nitrogen amongst the bark and soil. Collectively we call this "Green Waste". It would normally be taken to landfills where it is a waste of a natural resource.
Keep any wood mulch away from the trunks of new plants about a foot for the first few years until the bark on the trunk gets woody. If they grind out the stump of the tree with a stump grinder, those are some of the best wood chips. Good luck!
