Trees are exposed to all sorts of harsh elements. Therefore it is not surprising that many trees in Edmonton crack during storms. Many customers are led to believe that the only alternative is to remove the tree and start over. However, trees can naturally heal over wounds if properly secured. In an effort to save trees which have sentimental value to the customer, Tree Ninja provides tree cabling in Edmonton. Customers who have a large tree and wish to prevent the likelihood of cracking can also have their trees cabled.
Tree cabling is the mechanical fastening of a tree’s canopy to prevent it from splitting further. We use very strong, German, synthetic cables rated up to 2- tons. Once installed, they are designed to be able to adjust as the tree grows. This prevents girdling which can suffocate the tree. We can also install shock absorbers if no crack is present. It is recommended that Tree Ninja is brought to inspect the cabling system annually.
Co-dominant conifers are also fantastic candidates for tree cabling. A co-dominant stem is when there is more than a single stem branches from a conifer’s crown. It is recognized by its tuning fork shape (U). It is easily identifiable by our ISA certified arborists. The union between the multiple stems is notoriously weak. The reason being they are no strong wood fibres holding the crown together, instead only bark and sap! If a tree cable is installed it will likely save the stems from splitting during a storm.
Once hired to install a tree cabling system our arborists will first assess the condition of the tree. If the tree is compromised, our bucket truck or aerial lift may be required. Once a safe method of accessing the tree’s canopy has been found, we attach our tree cables to the strongest stems and cinch them together. Sometimes a triangle pattern will be used to depending on the positioning of the dominant stems. We always install special fabric which reduces the friction and wear on the bark of the tree. A pulley system may also be used to bring the stems together prior to tightening the cable. The great advantage of our cabling system is that no drilling into the tree is necessary. We are also able to adjust the tree the cables as the tree grows in taper. After the cabling system is installed, our arborists will show their work to the homeowner if present.
Are the tree cables an eye-sore?
Nope. Our cables are black and blend in with the shadows of the canopy. To be honest, we often have to point out the cabling system to the customer otherwise they would not have been able to see it!
Can I cable a tree myself?
We do not recommend it. The use of ratchet straps or chains is known to damage the cambium of a tree. Proper tree cabling kits have to be specially ordered and professionally installed.
How much does it cost to cable a tree?
Cost is very dependent on the size of a tree and the number of cables that need to be installed. Tree Ninja offers free quotes in addition to determining if a customer’s tree is a good candidate for tree cabling.
How often do the cables need to be adjusted?
We recommend annually. A cable system has a life span of 7 years. However, trees are living, changing organisms and the cables should be continually inspected to ensure they are helping the tree.
Tree Ninja’s priority is to give our customer’s as many safe options as possible when it comes to their trees. Not all split or damaged trees can be saved, yet many younger trees can. Although it requires extra training and equipment, we never want to make a customer feel like a removal is the only safe option. Cabling has been a perfect solution for many of our customers in Edmonton including the iconic fig tree in West Edmonton Mall near the pirate ship. With the increasing number of windstorms in Edmonton, there has been a growing interest to protect and heal our city’s trees. Tree Ninja has been able to do just for many customers across the city.
