Nothing has really come close to peat Frank. Not convinced about the conservation argument.
The very best mulching material is seaweed. Used to get loads of it from the beach. My car boot full of seaweed and jumping flies. Put down in autumn it would prevent weeds, not supply weeds either, deter slugs and snails from breeding and provide an excellent soil conditioner. Although mild here seaweed protects against frost .....the air pockets create good drainage and the salt content seems to provide extra heat. Ideal too for hellebores
