It can cost up to $1,000 to have a tree professionally trimmed, depending on the height and condition of the tree. DIY tree trimming is a lot less expensive, especially if you already have the equipment. But is it worth it? Tree trimming is a skill that is not easily learned. What's more, trimming involves a lot more than making the actual cut. You have to know which limbs to take and which ones to leave in tact. You must also be able to appreciate the overall aesthetic of the tree. If you don't have the knowledge, you shouldn't trim a tree. Following are four more reasons why you should leave tree trimming to the professionals. 

Compromised Tree

Trees have hidden secrets that can make them dangerous to work with. A tree may look completely healthy on the outside while it is rotting away on the inside. Disease, rot and pests can all undermine the structural integrity of a tree, making it very dangerous to work with. If you don't know what to look for, you could cause a chain reaction of events that results in injury and/or property damage. 

Tree Trimming Injuries

In 2012 alone, nearly 50 people were injured while trimming trees. This number only represents injuries sustained by non professionals. Unfortunately, half of those injured didn't survive their injuries. Most injuries occurred because the tree or portions of the tree fell on the trimmer. A smaller number were injured by falling. Professionals aren't even safe from injury. According to the CDC, more than 1,200 deaths were reported among tree care workers over a 15 year span. 

Property Damage

Falling branches don't always go where you want them to go, which is why there is a great deal of property damage associated with DIY tree trimming. From broken windows to damaged roofs, all sorts of damage can occur as the result of falling branches and other materials. 

Ugly Results

Aesthetically speaking, many DIY jobs don't look that great. You must trim a tree in such a way as to maintain balance while thinking about future growth as well. If you make a mistake, you can't correct it. You must make sure that you're going to be happy looking at the results of your trimming project for years to come. 

It may look easy, but tree trimming is anything but easy. It takes professionals a lot of time to hone their craft. So if you need a tree trimmed, it's best to hire someone who knows what they're doing.
