Wood rot, or wood decay, occurs in trees due to the presence of various types of fungi. The fungi begin to break down the wood within the tree, thus causing it to weaken. While severe cases of rot may be obvious in the form of large downed limbs, damage to infected trees is not always apparent.

How do you stop a tree from rotting?

Use a trowel to dig out any soil or mulch from around the root crown to eliminate excess moisture. Check the tree for anything that may contribute extra stress, such as insect infestations or poor drainage. Eliminate any areas of concern. Fertilize with a high-phosphorous fertilizer to promote root growth.

How many years does it take for a tree to rot?

The computer model calculates that the “residence times” (how long a tree will take to completely decompose) for conifer species range from 57 to 124 years, while hardwood species are typically around on the forest floor for 46 to 71 years.
