Support Systems

There are many considerations before installing such systems and sometimes it is more appropriate to remove the tree or offending limbs. However, cable bracing and propping of trees is widely used to extend the life of specimens burdened with codominant stems, split limbs or decayed unions, particularly in old trees of historic interest or high value in managed gardens.  This may be worth considering if you live in Whangarei or in another of Northlands built up areas.

Lightning Protection

Thousands of trees are struck by lightning every year. Usually these trees die in time as a result of injuries sustained to vascular tissue and or secondary stresses and pests. Accordingly it is not safe to have trees substantially larger than surrounding buildings to close to them without lightning protection.

Fertilisation

Nutrition and fertilising is a balancing act.
