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…
There are a couple of widespread misunderstandings in our industry regarding the water needs of newly-planted trees. It is not uncommon to find the watering regime applied for a 400 litre tree is not materially different from that applied for surrounding tubestock – the same maintenance regardless of plant size. Read more…
AS 2303:2018 Tree stock for landscape use – Who grows conforming trees? The Australian standard for trees (AS 2303:2018) should be applied to tree stock for your projects. All our major tree growers are capable of growing conforming trees. But there is no externally audited accreditation scheme available in Australia Read more…
Following a series of slides showing rootballs of some Trees Impact stock displayed at a recent workshop for the Queensland Arboricultural Association in Cleveland [conducted by Ross Clark from Trees Impact] one delegate made the comment: “I have never seen rootballs as good as that and doubt anyone else here Read more…
