If you have the right tools and little knowledge of tree trimming and pruning, then it is better to not try it by yourself. The tools needed for such a purpose can be dangerous if you are not experienced at all. Mostly tools consist of sharp blades and are heavy to handle, and without proper protection, you could harm yourself.
You must have seen a lot of video of the incident happening with people who lack the skillet and knowledge for tree care. Most common mistake done by house owners is they don’t know in which direction the tree will fall. So don’t take the risk of harming yourself or inflict injury while cutting a tree for your DIY project.
