THE CHALLENGE: When you invest in new trees, you don’t just want them to survive – you want them to thrive. Of course, new trees need water and most short-term problems are linked to inadequate, excessive, or inefficient watering. (See ‘The Critical Importance of Moisture’). So, how much water should be applied, Read more…
Correct placement of the ‘root crown’ is essential for the long-term success of your trees. The structure of the roots of trees has evolved to suit life below ground. Similarly, the above-ground parts of the tree have evolved to live and grow above the ground. The junction where those below-ground Read more…
LOOK AROUND When you are next driving through an established part of Sydney, Melbourne, Newcastle, or any of our other major eastern centres (particularly just after a storm), look around you and note the trees that look to be the healthiest, the bushiest and make the greatest positive contribution to Read more…
Minimising damage arising from the interaction between roots and hard surfaces. THE PROBLEM As a tree grows the base of the stem expands (trunk flare) and the diameter of the primary roots increases, particularly close to the base of the stem. These two phenomena can result in the generation of Read more…
How do you compare different prices for what is, allegedly, “the same sized tree”? Is pricing based on container size fair? Is pricing by tree size more fair? What is “pricing by size”? Can “pricing by size” save you money? Pricing by tree size, as opposed to container size, offers Read more…
For the tree buyer/user, using AS 2303 and the concept of size index is an easy-to-use tool for assessing or comparing quality, compliance with specification and value for money between competing suppliers – given that trees are traditionally quoted according to container size only; and that tells us little about Read more…
At Trees Impact we persistently push the ‘quality’ message. (eg see Why Buy Only the Best Trees Available). But preach as much as we like, decision-makers actually need to see what we are talking about to appreciate that message. So… HERE ARE SOME PICTURES WORTH A THOUSAND WORDS… This subdivision was Read more…
Prolonged staking ruins trees. If trees don’t need to support themselves, they won’t. So they develop a dependency on the support provided by the stake, fail to develop the strength needed to hold themselves upright and collapse when the support is taken away. Sometimes this can be corrected with good management over Read more…
ROOTS SHOULD NEVER BE “OUT OF SIGHT, OUT OF MIND”. When trees with girdled roots are planted the visual, environmental and social benefits are all compromised. To make matters worse, where trees perform poorly or fail outright we are left with wasted money, wasted time, wasted opportunity and damaged reputations. Read more…
SHOULD THERE BE “GRADES” OF TREES AVAILABLE? It has been suggested to us by some growers that the standard for trees set by the NATSPEC specification is too high and that trees really don’t need to be that good. Our response to that is: If it is simply the act Read more…
