Container media amended with mature hardwood bark compost (CHB) suppressed chrysanthemum and flax Fusarium wilts, but green CHB was significantly less suppressive. Media amended with raw and aged pine bark were mildly suppressive and those amended with Canadian peat were conducive. Heating of mature CHB negated the suppressive effect, but only partially reduced the suppressiveness of green CHB.
