homemade soil question

Hey everyone. this is my first post.
I have done bonsai since 2003 and since that time i have used brussels soil, worked FINE, but EXPENSIVE!! this spring i decided to make my own soil.
It consists of 3mm-7mm: 2parts--sieved pine bark
2 parts riversand, pebble like stuff cleaned 3mm-7mm
1 part peat moss.
Does this sound viable to you. Its has been hit and miss for me... most pots drain well and retain well, but others are absolute swamp like... they dont drain unless you count going over the sides as draining. I am studying them and have tried everything except total repot which will damage the tree in mid summer. CAN ANYONE SHED LIGHT ON THIS PROBLEM. modify my soil mix if that what you recommend. thanks

Sounds to me like there may be a bit too much organic (peat moss) in the mix. That is fine for some trees like Wisteria, Alder, Willow, Taxodium etc that like "wet feet" but can be too slow draining for pines and many others. If it becomes a problem, water only when needed and adjust the mix next spring when repotting.

seems to me the best answer i have heard on soil is experience. start with what u know and work off that! u'l get it down to a science my friend...

I think you do have too much organic material in your soil. I dunno exactly where you live in the "eastern broadleaf biome" (it's a huge area!!) but climatically it is a very humid area. I'd suggest your next soil mix be something on the order of 1/3 Turface (high-temp baked clay), 1/3 river gravel and 1/3 composted pine bark mulch.

You can raise or lower the organic portion depending on the tree planted in the individual pot -- more for azaleas, less for conifers.

LOL! the eastern broadleaf biome is a big area. maybe i need to look at that one again.... just being safe on the location thing to avoid theft. my bad. lol

to all the other responses.... I have considered getting turface... or calcined clay... i ran across some at a garden center as a water plant gravel. I cant find it anywhere these days. ANY one have an idea where i could get the calcined clay myself in the southern ohio region? THANKS!

As far as geographic info goes, You can easily pinpoint yourself enough that folks can help and still avoid thievery. See my sig below and info to the right ------>

I think John Deere Landscape stores across the country all carry Turface.

this would be decently close enuff. What do they offer here? thanks

Green Velvet says they have Turface, you want Turface MVP or Turface Pro League - The Turface Quick Dry is MUCH too fine a particle.

thanks billy. Now do i need to seive the tuface when i get it or what is recommended? thanks for your help.

Purists sieve it, and so do I -- at least with the first bag. I use the fines for my mame. And sine there will be a LOT of fines, I'm lucky I have a lot of small trees.

Later bags don't get sieved because I'll have all the fines I need for all of my twice-yearly repotting of my tiniest trees.

I mix 20 - 40 % composted pine bark with the Turface; percentage depends on what I'm repotting.

(Incidentally, Turface is a trade name and is trademarked and all that jazz. It should be capitalized. FWIW.)
