Soil conditioners

I have been using peat moss as a soil conditioner for some years now, but I’m beginning to rethink that because it is acid (more of which we don’t need here), and I read something about it also containing microorganisms which may be not helpful. A trade professional whom I trust has suggested that I try coconut coir instead, since it does not have the same disadvantages and also lasts longer. I believe he said it would last about three years before breaking down in the soil, so that would seem to work fairly well in a daffodil bed rotation.
