Some woods will rot under water. Others are extremely good. -Did you know while exploring the Titanic wreckage a few years ago, they brought up some teak deck chairs that were in almost new condition - after all those years under seawater.
The disadvantages of Ash wood is that it is not as rot proof or water resistant as other hard woods. If it is left untreated, it will rot quickly.
It might be where water has made the wood rot or some kind of dent sry if im wrong
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. But to give a very basic idea soft wood will start to rot in the outside normal environment where you have rain, cold dry spells across a year in about 6 months hard wood will go substantially longer
Decomposers cause wood to rot.
Spruce is a tougher wood, but some pines, like yellow pine, are much more resistant to rot under water. Yellow pine is often used in boatmaking.
It rots faster in the water because it gets all moldy/ green
Wood can be treated with various preservatives to prevent rot and infestation.
Dry rot is not actually dry,,,,,, It decays wood by keeping it damp and allowing the growth of bacteria,,,,, To prevent it get it away from the water source and allow plenty of air ventilation.
Most often where the wood meets the soil. Heavily shaded, or poorly drained areas will also hasten wood rot
The main cause of wood dry rotting is a brown rot fungi called Serpula lacrymans. These spores get onto wood and slowly eat away at the wood, causing it to slowly rot out.
Yes, it can.
Cedar doesn't rot because it is water resistant and if it isn't sealed it will last you pretty long. It can last up to 8 years if not sealed *After "8 years" then what? Cedar rots like any other wood if you wait long enough. How long depends on factors such as how much water can get trapped where two cedar parts touch or how severely it is constantly dried out (dry rot).
