Cabling and Bracing
Cabling and braces are used to provide structural support to a tree. The cables and bracing are generally a high quality of steel able to withstand the growth of a tree and natures elements. It’s rare that this is needed, but it will save large branches from falling and causing damage during high wind storms as stated on evernote
Trees and plants have very specific needs when it comes to watering. If a tree receives to little water it can become susceptible to disease and death. If the tree receives too much water then root rot becomes a concern. Arborists can develop systems to ensure a Tree is receiving the correct amount of water.
For mature trees pruning is required to remove dead or dying branches. This thinning out of branches strengthens the tree. For younger trees pruning is necessary to remove lower unneeded branches so they do not become a hassle latter on. This is not needed in the wild because the trees are all competing for top sunlight and therefor lose lower branches early on in life.
Insect and Disease Prevention
Certain types of insects can eat through leaves and even branches damaging your tree. Arborists are able to identify which types of insects are doing so. In addition disease through things like fungus can damage trees as well. Through advanced means arborists are able to identify tree disease and treat it properly.
Arborists are master horticulturist who specialize in trees. They can identify just about any tree. If you are planning on having a new tree planted they can tell you the best ones to plant based on the regional climate and what you’re looking for out of the tree.
