Professional Opinion on Tree Diseases From Heaven Contracting

It is recognised that Kiwis have a ‘do it yourself’ attitude to chores and maintenance around their properties, but in the case of tree diseases and their symptoms, Heaven Contracting recommend we should hire a professional every time.  

As they point out, there are countless species of tree in New Zealand, and some are more susceptible to disease, due to soil quality, climate, water levels or location. Many of these diseases go unnoticed, particularly if you aren’t an avid gardener, and only notice problems when you see signs of significant decay.  

Without the help of a professional, it can be incredibly difficult to pinpoint which pathogen is responsible for the symptoms in your tree or shrub, but Heaven Contractors say there are certain signs to look out for that will determine the health of your garden. Bacteria and fungi symptoms can grow randomly across the whole tree or shrub, a clear indicator being the appearance of wilting leaves, drooping downwards and turning a dull, brown-grey colour. The presence of cankers (sections of dead bark which appear along the trunk) indicates a nutrient blockage which is usually transported from the roots upwards. 

In trees, heart rot is a fungal disease that causes the decay of wood at the centre of the trunk and branches. Fungi enter the tree through wounds in the bark and decay the heartwood, and the diseased heartwood softens, resulting in trees being structurally weaker and prone to breakage. Root rot and decay also suggest the presence of pathogens and, if identified early, can be treated before a complete blockage of nutrients and water to the canopy kills the tree entirely.
