How not to stake trees.
This is an excellent example how not to stake a tree.
This is a Eucalyptus erythrocorys tree growing in a road verge in the City of Mandurah.
The tie is too high, it is too tight and it has been left on too long.
Trees staked like this have not been given the opportunity to strengthen their roots by moving in the wind. Wind movement encourages the trunk cells to become more flexible and it also encourages the roots to spread, giving more support to the tree.
When staking trees like this the trees tend to grow taller causing a decrease in trunk diameter. Another reason for the tree to become weaker.
A tree grown in more natural conditions will develop a more supportive trunk that should support the tree for its whole life.
How not to stake a tree.
This is the result of making the tree tie too tight.
With the expansion of the tree trunk as the tree grows, the tree tie is ringbarking the tree, which will ultimately kill the tree.
With this particular tree in a City of Mandurah road verge, a concerned resident removed the tie to stop the ringbarking of the trunk by the tree tie. Soon afterwards there was a strong wind and the result you can see below.
The tree stake has been removed and the tree is unable to support itself.
Photographed from a different angle you can see that this tree was flowering with the beautiful red caps and bright yellow flowers of the Eucalyptus erythrocorys. It would be impossible to save this tree.
This shows how the tree has become too weak at the root level and was unable to hold itself up.
This is an example of very poor staking of a young Jacaranda tree in a City of Armadale car park.
Cable ties should definitely not be used for staking trees.
Here the cable ties are so tight that they are already strangling the tree.
Another Jacaranda in the City of Armadale car park. This has also been staked using cable ties.
Using one stake like this also restricts the movement of the tree and when the stake has not been installed deep enough, it falls over along with the tree.
Another example of poor staking by City of Armadale. Corymbia maculata poorly staked using 3 stakes that are too tight, too high and too low. This stops the tree from having any movement at all.
