Orchiata bark delivers five core benefits: a 5+ year lifespan without rotting, pre-set pH between 5.5 and 6.5, pathogen-free processing, grade-specific AFP and WHC calibrated to plant size, and no salt accumulation requiring flushing.
Those benefits trace back to how Orchiata is processed. New Zealand Pinus radiata is aged — not composted — so only the outer bark surface breaks down, leaving the core hard and structurally intact far longer than conventional fir bark. Natural Dolomite added during processing locks pH and supplies calcium and magnesium before the bark ever reaches a pot. Beneficial micro-organisms that survive aging actively resist pathogens. The result is a substrate that performs consistently from first potting to year five.
- Orchiata bark lasts 5+ years in the pot — 2 to 3 times longer than conventional fir bark, which compacts within 6–12 months.
- Orchiata's pH arrives pre-set at 5.5–6.5 via natural Dolomite added during processing — no adjustment needed before use.
- Orchiata EC stays below 0.3 mS/cm, meaning no salt accumulation and no flushing required.
- Orchiata Classic grade carries AFP of 47–52% and WHC of 55%, measured at container capacity after drainage.
- Orchiata is available in five grades from Precision (1/8"–1/4") to Super (3/4"–1"), each with distinct AFP and WHC values matched to pot size and plant stage.
