I make my own pine bark fines. Buy a bag of regular pine bark mulch, sift it through a 1/4 inch wire screen and voila - pine bark fines AND the larger chunks are left over for bark mulch in your garden. And just as a note - since my daylilies will be staying in their pots permanently it's important to have the addition of the Aquarium gravel to compensate for the bark fines which will break down in about a growing season or so. The soil may then become more compact then is good for the daylily. If you are just potting for the short term you may skip it I guess, but from my experience, its better to add it then tons of perlite as a solution to the inevitable bark fines decay. ....Maryl
