wood chips in bonsai soil affect pH
I have just completed sifting perlite, lavarock, drystall, and fired clay. The mix looks good, but lacks organic matter. Ive looked through all my books, it seems they use peat for organic matter. But how do you sift it, because if you keep sifting it, it all becomes dust and goes through? So then I took some soil conditioner (smells like its made of ground up pine mulch) and sifted out the larger peices and used them. Will the pine bark will be too acidic? Should I use peat instead, even though its particles are very small and will fill in between my pourous mix? What about introducing mycorrizae some how? Due to being a med student and possibly not having time to water every day, would using a 50% standard potting soil/ 50% inorganic mix, work, or would this be too much dirt and would defeat the whole purpose of even attempting to make bonsai soil?
Thank you for any help you can offer,
