The team from Heaven Contracting provide a range of services for residential and commercial properties and landscapers, including tree removal, treepruning, stump grinding, hedge trimming and mulching. They also offer advice on tree diseases and their symptoms.

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 decayof wood at the center 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.

Regarding pests, the most obvious indicator of a pest infestation would be seeing the insect with your own eyes, confirming any doubts you may have had. Some other common symptoms of pest infestations include discolouration, curling, spots and holes in leaves. Branches may look dull and become fragile, making them susceptible to breaking and falling. The tree’s trunk may look cracked and be flaky, signifying poor health and a lack of nutrients.

Heaven Contracting recommend regular maintenance, and hiring a professional arborist will take the stress out of maintaining your garden when you don’t have the time. At Heaven Contracting, they offer complete maintenance, including tree trimming services, tree pruning services and tree removal when necessary, so for more information, visit http://arboristauckland.com/ today.
