SAWDUST COMPOST: Potting Medium for Cymbidiums Mixed with fowl manure; it is successful with some growers; breaks down easily; can cause root rot; sawdust from "treated" timber may also cause root rot; fowl manure might contain elements harmful to the plant; however, a test repotting in another mix was no more successful so the mix may not be the fault. AU71-33 0
SAWDUST, REDWOOD: As Potting Media Excellent culture of cattleyas was obtained in redwood sawdust in a commercial grower's collection near the Californian southern border. OD69-173 0
