Porous Paving

11. March 2009

Hard paved surfaces such as roads, car parks, driveways, and courtyards cover a significant proportion of urban areas. Impervious paving increases peak and total storm water discharge increasing demand on existing stormwater infrastructure and increases downstream flooding. Rapid discharge of storm water deteriorates stream habitat through bank erosion, while runoff from impervious surfaces [...]

Heat combined with water stress, Autumn comes early…

Heat stress
According to Kozlowski, Kramer & Pallardy (1991) the thermal death point of most active plant cells varies from 50 to 65C. This is dependent on species, age of tissue and duration of exposure to high temperature. However, high temperatures below the thermal death point can often damage woody plants. Symptoms of this type of [...]

The City of Melbourne is internationally recognised for its tree-lined boulevards, parks and gardens. Trees beautify, define and soften landscapes and give scale to buildings in addition to providing shade and wildlife habitat. Trees are the most life enriching of all the types of vegetation [...]

Carbohydrate and Surfactant Treatments

12. September 2008

0 Comments

Recently published research in the application of carbohydrates (sucrose) in root drenches has shown considerable promise in improving general plant health whilst limiting the effects of environmental stresses and even herbicide damage. Peer reviewed and published research on field trials conducted on containerised plants, young transplanted and established mature trees demonstrated that carbohydrate treatments applied [...]

Fertilising Trees

11. March 2008

0 Comments

Fertilising trees refers to the practice of adding supplemental nutrients (chemical elements) required for normal growth and development.
You can’t ” feed” a tree, since trees produce their own sugar via photosynthesis, for which they use nutrients as part of the process.
A reasonably fertile soil will have enough nutrients to satisfy the requirements of growth on [...]

Mulch for trees

2. March 2007

0 Comments

Peoples awareness of the potential benefits to gardens of using mulch has increased markedly over the past few decades. With the recent limitations imposed on domestic water resources and the implications for water use in the garden, plant moisture stress caused by drought is becoming an increased cause of tree decline. Mulch is [...]

Watering mature trees

27. October 2006

0 Comments

Mature trees can have large water requirements and may lose up to hundreds of litres of water daily through their leaves, especially in hot and/or windy weather. Trees will experience stress if insufficient soil water is available for use by the tree to replace the water lost through the leaves. Continued stress can lead [...]
