what size sifter do i use when shifting through my bark, peat, and perlite?
Pine bark fines are partially composted pine bark. Fines are what are used in mixes because of the small particle size. There will be a naturally occurring "perched water table" (PWT) in containers when soil particulate size is under about .125 (1/8) inch, so best would be particulates in the 1/16 - 3/16 size range with the 1/16-1/8 size range favored.
No need to sift the perlite unless it's mostly dust.
You don't sift the peat, uuse as is. Only one part of peat to 5 parts of bark and one part of perlite.
Don't forget to lime, adding about 1 Tbsp. per gallon.
Hope this helps.
