[IBC] Bonsai mix - source for organic component(s)
Hey Bill,
Thx info! I read, I comprehend, I like Turface MVP is a little on the small side, Turface pro is even a bit smaller. Is the lava-rock/grat-grit a bit bigger? Best, /jhd Central Tennessee, USDA zone 6a-6b, Sunset zone 33 "Corcoran. Bil" wrote in message news:672C834D0A1E974CB1B26D66252A6B41076307@mail01 .kings.edu... John: I find it does well for water retention. Since I have an automatic irrigation system I'd rather use a fast draining soil to minimize the risk of over-watering. I try to keep Biogold chunks in each pot as a food safety net and I tend to hit them every other week in the growing season with Dynagrow or fish emulsion. I was using 1/3 Turface MVP, 1/3 Grant-Grit (decomposed granite/chicken grit) and 1/3 composted pine bark mulch. This was based on several recipes I had read. After talking with Jerry Stowell about his concerns with the alkaline in the chicken grit and after my struggle to find a reasonable organic component year after year I started checking out more soils. I spoke with Chase Rosade and with Jim Doyle from Nature's Way and after checking out their soil mixes I decided to drop the organic component completely. I now use lava rock and Turface MVP in pretty much equal parts. It holds moisture, drains well and does not break down and clog the soil at all from what I have seen so far. It is still an experimental soil but I can say I'm using it in almost all of my plants, it's affordable and easy to sift. My concerns for this soil mix: 1) All feeding is controlled manually (Probably a good thing) 2) Ph of lava rock (I heard some of them are high depending on the source) 3) Hardness of the mix (Doesn't allow fine root to penetrate like Akadama) If the price was right I'd try Akadama instead of Turface or maybe instead of both but it's too expensive and it does break down more quickly than I can afford to replace it. wmcorcor == -----Original Message----- == From: Internet Bonsai Club ] On Behalf == Of John Dhom == Sent: Thursday, July 01, 2004 1:55 PM == To: == Subject: [IBC] Bonsai mix - source for organic component(s) == == Heya Bill, == == Well... it'd certainly be easy as I have good sources for the inorganic == components == == Does this have a significant impact on water/nutrient retention?
