Is orchid bark toxic?

No, orchid bark is not toxic to humans or plants. Orchiata orchid bark is 100% Pinus radiata bark — no chemical treatments, synthetic binders, or toxic additives at any stage of processing.

The only substance added to Orchiata orchid bark during production is natural Dolomite, a calcium magnesium carbonate mineral applied to correct pH. Dolomite is a standard horticultural input and is not a health or safety concern. Because Orchiata orchid bark is chemically untreated throughout aging and processing, it introduces no toxic compounds to the root zone — an important distinction from some treated or composted wood products sold as orchid media.

• Orchiata orchid bark contains one additive: natural Dolomite (calcium magnesium carbonate), added for pH correction only.
• Orchiata orchid bark arrives pH-stabilized between 5.5 and 6.5 — within safe range for all common orchid genera.
• Orchiata orchid bark EC stays below 0.3 mS/cm, meaning negligible dissolved salt load in the root zone.
• Orchiata orchid bark is 100% Pinus radiata — no chemical treatments, preservatives, or synthetic coatings applied at any production stage.
