Cypress Tree Roots
As a common tree growing in wetland areas, cypress trees have special tree roots which enable them to survive in water. Most of them can grow more than 50 feet in height and can live up to 200 years. It is a fast growing tree during the first ten years and the growth will stop after 50 years old. It is famous for their dual root system which helps them grow happily in swamp environment.
Most cypress trees have two types of roots, namely the main roots and the secondary roots. The secondary roots will spread wider than the main roots which can help to absorb more nutrients from soil. Cypress trees have a special part called knees which is essential for its breath. The knees are a part of the root system and they will emerge above the water for fresh air. They will form a line around the main trunk and can read up to 5 feet above the water. They also have some small knees which extend further as well. Generally, the size of the root system of the cypress trees can equal the size of the tree size in most circumstances. Some big cypress trees can spread their roots to more than 50 feet underground. These roots are important parts for trees to transport nutrients to the tree body.
The cypress roots growing in water can be susceptible to some diseases such as Phytophthora Root Rot and Annosus Root Rot. The former disease is caused by a special mold growing in water. They can affect the functionality of the small roots and weaken the health of the tree. The latter one is generally caused by fungi and be contagious to nearby cypress trees as well. Some chemicals can help to control the spread of these diseases.
