POTTING MIXES: New Developments in the Sixties Many growers prefer two parts bark and one part redwood bark fiber; or, 60% bark, 25% coarse peat moss, 15% redwood bark fiber and 107o coarse perlite, all of this rather than straight bark because they hold water better, are easier to water and prevent passage of snails to the roots.

POTTING MIXES: Phalaenopsis In California, Hugo Freed found straight bark to be the ideal mix. FRlllTree-fern and redwood mix is common in semi-tropical areas; fir bark and redwood are used in northern climates where decomposition is less rapid; redwood chips have a low pH value. A71-105 0
