I screen & measure everything when it's dry, then dump/pour them into the mixing tub, but moisten the ingredients before I mix them together.

I usually start screening Turface on nice days during late winter when I'm in the mood, & store it in large containers. The bark and cherrystone comes prescreened, but I still give it a quick screen over insect screen to get the dust out. I don't rinse, just because of the volume of soil I go through in a year (well over 150 gallons - about 10 bags of Turface worth in most years), but I do agree it's a good thing to do if you have the ambition. ;-)

Hi, Marie!

I do the same as Al. I find that I can separate the bark dust easier if it's all dry.
Once I mix the ingredients, I add some moisture that diffuses between the particles.
