Healthy soil, potential breakthrough research

5. July 2010

Healthy soil differs from dirt in the myriad of life forms it contains. Soil organisms (the biological properties of a soil) aerate, decompose plant material, assist nutrient absorption, build soil structure, reduce water requirements and play a vital role in the nitrogen cycle. A proper balance of nutrients and pH obviously play a significant role [...]

Porous Paving

11. March 2009

1 Comment

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 carry pollutants [...]

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 [...]

by Ian Shears. Senior Tree Planner. City of Melbourne City of Melbourne Experience 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 [...]

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 [...]

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 gaining attention [...]

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 to [...]
