I arrived in the Gulf over 20 years ago, full of energy, ready to make streets greener and cities more liveable. But it didn’t take long to realise something was a problem with the trees in the city.
Trees were stunted, leaning, or failing altogether. Not one or two. Many. Something wasn’t right.
Problems in the Nursery
After 20 years of working across the region, I can say with confidence: better quality nursery tree stock would transform the quality of urban forests in the region. Problems with trees start long before they’re planted. The core issue is root defects—circling, girdling, J-roots, kinked roots—almost always caused by poor nursery practices. Once these structural issues are locked into the tree’s root system, the damage is done. No amount of staking will fix it.
In fact, bad staking often causes even more problems, including weak taper and dependency. Yet we keep blaming the wind, or the contractor, or maintenance.
I started digging deeper. I read everything I could. I studied trees in the ground and in nurseries. I searched for global best practices—real standards backed by research.
Standards!
Eventually, I found my way to AS 2303:2018 – Tree Stock for Landscape Use, an Australian standard based on years of national research across thousands of trees. It doesn’t just talk about what a tree should look like—it provides testable, practical requirements for:
- Visible root flare
- Correct root direction (radial and downward)
- Absence of circling, girdling, or kinked roots
- Balance between canopy size and root volume
- Minimum rootball stability and structure
This was the standard I had been looking for.
I travelled to Australia to meet Ross Clark, the author of Trees for Urban Landscapes and one of the key figures behind AS 2303. Ross is the Director of Trees Impact Nursery, which applies these standards in the real world. That visit was transformative. Meeting Ross and the passionate team at their mature tree stock nursery re-affirmed the truth that quality mature nursery tree stock was possible given the proper practices. Root management was key, including periodic root pruning according to species.
Adapting the Standard to the Gulf
Having met the man behind AS 2303, seen the results of good nursery practices, I know the Gulf market needed better specifications to drive quality of nursery tree stock. I developed a MasterFormat specification:Section 32-9343 – Tree Stock Assessment and Testing.
This specification translates the core principles of AS 2303 into a practical framework tailored for Gulf projects. It includes:
- Above-ground criteria like form, taper, health, and structure
- Below-ground criteria including root direction, root division, and rootball integrity
- Sampling strategy at dispatch for randomised quality control
- Clear rejection criteria for both individual samples and entire batches
- Visual guides for identifying root defects, poor unions, and structural flaws
- Tree Stock Balance Tables that match container/rootball size with canopy dimensions
In short: it tells you what to check, how to test it, and when to reject stock. It gives landscape architects and clients the tools to insist on better trees—and stop wasting money on future failures.
But Specifications Alone Aren’t Enough
There’s a deeper issue here: widespread misinformation.
In the Gulf market, we see common myths repeated over and over:
- “Just stake it better.” (No. If the roots are defective, it will still fail.)
- “The tree will straighten as it grows.” (Not if the root flare is buried or the rootball is circling.)
- “It passed BS 3936, so it’s good stock.” (BS 3936 doesn’t assess root structure at all.)
We need a culture shift. We need to stop treating trees like consumables and start treating them like long-term infrastructure.
What needs to change
- Education: Designers, contractors, and clients all need better understanding of how root systems work and why tree selection matters.
- Procurement: Stop accepting poor stock. Inspect trees at the nursery. Demand root exposure.
- Specifications: Use AS 2303—or a Gulf-adapted version like 32-9343—as your baseline.
- Accountability: If a tree fails due to bad nursery stock, the blame belongs upstream.
The trees we plant today will shape the future of our cities—if we get it right. But if we keep cutting corners, we’re just building green disappointment into our urban fabric.
Let’s stop wasting time on excuses, and start demanding quality from the ground up.
