Stormy Weather and the Effect on Trees
Generally, trees can withstand abnormal weather conditions providing the trees are healthy and in good sound condition. Some parts of New Zealand are particularly known for their windy conditions such as Wellington (though the Manawatu has tried to claim they have more https://www.stuff.co.nz/manawatu-standard/news/73147296/is-palmerston-north-the-windiest-city-in-new-zealand )
Unfortunately, trees grow a lot quicker in New Zealand’s conditions and therefore are not quite as stable as their counterparts in the northern hemisphere. Also, I come across large trees which have had their roots disturbed by digging trenches for foundations and putting driveways in. Urban spread and in filling of residential houses ultimately has major effects on the health of large trees.
Cutting tree roots can have a significantly detrimental effect on the stability of the tree and its longevity of life.
Also, concreting near trees where their roots have been cut, can cause issues with the tree health where the lime from the cement leaches into the soil and contaminates the area that the tree needs to draw it nutrients from.
As Arborists we can advise people on the potential risk of having a large tree, whether it is in decline, showing signs of decline, or completely healthy. It may be that the tree is located close to a house, or over the road or powerlines. Some large trees can weigh up to 10 tonne and will cause significant damage if they fail.
Arborists’ training emphasizes the long-term health of trees, and arborists know how to check tree health from the roots to the leaves. Their years of observing how and where different species do or don’t do well can help you decide the right spots for the right trees.
Sometimes we suggest that removing some weight from the tree can lessen the chance of the tree failing. Also, certain trees are more susceptible to failing than others, for example a tall single leaded Redwood or Poplar can be a lot stronger than a multiple branched Liquid Amber.
Arborists specialise in the care of individual trees. They are knowledgeable about the needs of trees, and are trained and equipped to provide proper care and advice.
So, if you have a large tree or trees on your property that you would like some advice on, please don’t hesitate to ring us to schedule a time for our head arborist to visit you on site.
