Tree Doctors is committed to using 100% eco-friendly biodegradable chainsaw lube.

Other arboricultural companies commonly pollute our Wellington soils with cheap petroleum based chainsaw lubes and spread hundreds of litres of contaminating oil every week.

TREE DOCTORS uses Stihl Bio chain bar lube that is derived from plants and completely decomposes in the ground within a short space of time.

Our chainsaw bar lube has been tested according to OECD Biodegradation Test 301B and has been awarded the 'Blue Angel' ecology mark and the European Eco-Label.

Arboricultural Terms


Thinning and Dead-wooding

Thinning a tree will lighten the crown and allow more sunlight to pass through the branches. It will leave an even, well-balanced branch structure. The process involves the removal of thin, weak and crossing branches, including as many secondary branches as necessary to achieve the desired level of thinning. Usually between 20-40% of the total volume of the tree, depending on the tree species, will be removed.

Dead-wooding will remove significant dead wood in the tree. Full dead-wooding will attempt to remove all dead wood in the tree.

Crown Lifting

Crown lifting will remove the lower branches, so as to provide a desired clearance above ground level or structures. The crown will be lifted by either completely removing lower branches or parts of branches that extend below the desired height.

Crown and Height Reduction

The reduction of the crown of a tree will make it smaller, while retaining good shape and greenery. Outreaching branches are cut back to a suitable fork, bud or well into the trunk of the tree. Crown reduction is not suited to all trees. The natural shape of the crown is retained and minimises hazards of dysfunctional problems in tree circulation. A reduction of greater than 30% of the existing foliage structure will not maintain all aspects of the integrity of the shape of a tree. Reduction past this is commonly known as “topping” or pollarding. TREE DOCTORS do not recommend pollarding.

Pollarding

Pollarding trees was a common horticultural practice in New Zealand up until the late 1960’s. It is now considered an undesirable practice within the arboriculture and horticulture industry and a last resort. Pollarding will remove all the greenery from limbs leaving bare cut branches or trunks. Trees will be shocked by the procedure and, depending on the species of tree, produce multiple new re-growth tips near the cut ends and within the internal branches of the tree. Trees may become disfigured for the rest of their lives following this procedure or, at worst, die. The dominant factors determining a tree's ability to recover from pollarding is determined by its species, age and the sunlight cast on the tree. Pruning the new wood can help form a new canopy several years after the pollarding and + TREE DOCTORS has had proven success by staging this work on very large trees in Wellington over a period of 18-24 months. Orchardists commonly pollard fruit trees to encourage new growth at a desirable height. We prefer to never pollard trees. Rather it is better to fell and remove the tree completely and replant with a more suitable tree or shrub.

Dismantling and Felling

Dismantling a tree will reduce the tree to a pile of debris. Felling will, in most circumstances, create the same outcome, unless the tree is felled whole and left mostly uncut.

Manageable Lengths

Cutting lumber into manageable lengths will leave portions that can be lifted by one or two people.

Firewood Lengths

Cutting into firewood lengths will leave the lumber as 30 to 45 cm lengths. This wood is not split.

Trimming and Topiary

Trimming is completed with hedge trimmers only. Trimmed trees and hedges will, over time, develop the specific shape and size desired. Regular 6 and 12 monthly trimming is what makes a good hedge.

With topiary, many formal, geometric or creative shapes can be formed over time. Repeated trimming and shaping of the plant will achieve the desired result.
