WOOD: Decayed, for Potting Mix For general potting use, decayed trees pine and cedar (in California) were crushed, passed through a half-inch screen; soaked for a week in a nutrient solution of eleven chemicals; used successfully; refer to A58-107 0
WOOD: Greenhouse Construction The best two woods are redwood and cypress, the latter now difficult to find. A72-807 0
WOOD: In Potting Mix Bark removed from a tree by mechanical means rather than by the jet process has too much wood mixed in; it causes mycelium mold to form rapidly in the pot; it is possibly injurious to the plant; it becomes impossible to penetrate it with water; causes dehydration; modern bark seems to have lots of scraps of it. A79-29 0
WOOD: Pieces of Wood for Mounting How to clean it is to strip the moss off the wood, spray it with Cygon 2E, Diazinon or Malathion, and then use it. A77-449 0
WOOD PRESERVATIVES: Greenhouse Use The only dependably safe one is copper napthanate; zinc napthanate is a lesser possibility. A76-795 0
WOOD PRESERVATIVES: Injury Causes in the Greenhouse Creosote should never be used inside or outside a greenhouse; penta (Pentachlorophenol) should never be used either; it cannot be removed, but it can be covered; use a coating of linseed oil followed by an asphalt based aluminum paint; it's a good possibility for reducing damage to plants from fumes. A67-566 0
WOOD TREATMENTS: Anti-rot Treatment for Greenhouses Which Are Not Harmful to Plants Copper napthanate preparation sold under the names of Cuprinol or Kopex is the best. A77-619 0
WOOD TREATMENTS: For Greenhouse Construction of Wood Oil-borne preservatives are: creosote, pentachlorophenol and copper napthanate; the first two cause injury to plants with their fumes; water-borne treatments are: chromated zinc chloride, chromated copper arsenate and others which have only a slight effect on plants; for much data refer to A64-1029 0
