i just bought some bags of bark mulch from B& Q to mulch my beds. The smell was so strong I had to drive with the windows open. What do they treat it with, because that surely is not a natural smell of wood?
It depends what tree they came from as some barks do have a strong natural perfume.
Check the bag labelling carefully before spreading on your garden in case they have been treated with some noxious chemical that will damage your plants and/or soil.
