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).

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.

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…
