Wood Rot Wood rot is a type of fungal decay in timber, the decay comes in two catagories, white rot and brown rot. Decay usually starts when spores from the rot come into contact with damp timber. The damp timber (more than 20%w/w) allows the spores to establish themselves and grow using the wood as a food source. Symptoms of an attack of wood rot range from cross cuboidal cracking to mycelium on the surface of the wood and these symptoms vary depending on the type of rot, the type of wood and the conditions that the wood is subjected to.

Wood rot usually reduces the strength of timber and is often accompanied by a fungal growth called a sporaphore or fruiting body which is the heart of the attack and produces more spores which continue the life cycle of the fungus.

The most feared fungi is true dry rot (serpula lacrymans) which tends to cause more widespread damage than wet rot fungi

Wood rot is the decomposition of wood which occurs in large due to fungi consuming the wood. The fungi which cause the feed on the cell walls of the wood which contain cellulose and lignin. Limiting the moisture exposure of the wood will limit decay.

Moisture content is the critical factor that makes wood susceptible to decay. It must exceed 28%, and liquid water must be present in cell cavities before decay fungi can gain a toehold. Once established, some fungi can carry on their destruction at a moisture content as low as 20%. When moisture content falls below this level, all fungal activity stops. That's one reason why framing lumber is dried to 19% moisture content or less.

There is no specific time line. It is dependant on the wood and how much oil/resin it has in it, if the wood is a hard of soft wood, what the environmental condition the wood is in.
