The Science Behind the "Grow It Forward" Approach

Intro
When Scott Griffiths founded Great Scott Tree Care in 1976 he didn't call it the "Grow It Forward" approach. He just called it doing the job right. But nearly five decades later the science of arboriculture has caught up to what experienced tree care professionals have known all along — that the decisions made today about how a tree is planted, pruned, and maintained will determine the health, structure, and lifespan of that tree for decades to come.
This isn't philosophy. It's physiology.
What is the Grow It Forward Approach?
Before Great Scott begins any engagement — whether it's a single commercial property or a city-wide municipal tree management program — our ISA-certified arborists sit down with the client and establish both short and long-term tree care goals. We conduct a full assessment of every tree on the property, document current health and structural conditions, identify emerging risks, and build a forward-looking care plan that anticipates what your trees will need not just this season but over the next one to five years.
It's more intentional than calling a tree company when something looks wrong. And the science explains exactly why that matters.
Trees Don't Heal — They Compartmentalize
One of the most important things to understand about tree biology is that trees don't heal wounds the way humans do. When a branch is removed or a tree sustains damage, it doesn't regenerate new tissue over the wound. Instead it compartmentalizes — building chemical and physical barriers around the damaged area to prevent the spread of decay into healthy wood.
This process, known as CODIT — Compartmentalization of Decay in Trees — was first described by Dr. Alex Shigo in the 1970s and remains one of the foundational principles of modern arboricultural science. What it means in practice is this: the size, location, and timing of every cut matters enormously. A pruning cut made at the wrong angle, in the wrong location, or at the wrong time of year can compromise a tree's ability to compartmentalize effectively — creating an entry point for decay, fungal disease, and pest infestation that wouldn't have existed with proper technique.
This is why ISA certification matters. It's not a formality. It's the difference between a cut that promotes healthy compartmentalization and one that quietly shortens a tree's life by decades.
The 5-10 Year Growth Setback
Here's something most property owners don't know: improperly pruned or neglected trees don't just look bad — they can lose 5 to 10 years of growth. When a tree is stressed by improper pruning, disease, pest infestation, or environmental neglect, it redirects its energy away from canopy growth and root development toward survival responses. The result is a tree that looks alive but is spending years recovering rather than growing.
On a commercial property or municipal streetscape where mature trees represent decades of growth and significant dollar value in appraised landscape assets, a 5 to 10 year growth setback isn't an abstract concept. It's a measurable loss.
Proactive care prevents it. Reactive care — calling a tree company only when something looks visibly wrong — almost guarantees it.
Root Systems: The Hidden Half of the Tree
Most people think about tree health in terms of what they can see — the canopy, the bark, the branch structure. But the root system, which can extend two to three times the diameter of the canopy, is where the real story is told.
Soil compaction from construction activity, grade changes, improper irrigation, and root damage from nearby excavation are among the most common causes of tree decline in commercial and municipal settings — and they're almost entirely invisible until the tree begins showing visible symptoms above ground. By that point the root system has often been compromised for years.
Great Scott's assessment process evaluates root zone health as a standard component of every property engagement. We look for compaction, drainage issues, grade changes, and construction impacts that may be silently stressing trees that appear healthy on the surface. This is the kind of forward-looking evaluation that separates a proactive tree care program from a reactive trimming service.
The Spread of Disease: Why Early Detection Saves Trees and Budgets
Tree disease doesn't stay contained. Fungal pathogens spread through shared root systems, airborne spores, and insect vectors. A single diseased tree on a commercial property or HOA community isn't just a problem for that tree — it's a potential threat to every tree within spreading distance.
The window between early-stage disease and advanced decline is where intervention is both most effective and most cost-efficient. Treatment of early-stage fungal disease or pest infestation typically costs a fraction of what removal and replacement of a mature tree costs — and that's before accounting for the decades of growth lost when a mature tree is removed.
Grow It Forward means we assess for disease during every scheduled visit — not just when a tree looks sick. We look for early indicators like subtle bark discoloration, minor dieback, unusual leaf patterns, and soil changes around the root zone that most property managers would never notice. Those early signals are where the money is saved and where trees are protected.
The Economics of Proactive Tree Care
The science makes a compelling case. But let's talk about what it means for your budget.
A mature tree on a commercial property has a quantifiable appraised value. Depending on species, size, age, and location, a single mature tree can be appraised at anywhere from several thousand to tens of thousands of dollars in landscape asset value. When that tree fails — whether from storm damage, disease, structural failure, or pest infestation — the cost includes not just removal but replacement, establishment care, and the decades of growth that cannot be accelerated.
Proactive tree care programs like Grow It Forward typically cost significantly less per year than the reactive emergency spend that poorly maintained properties experience. The math consistently favors prevention.
There is also the liability dimension. A documented proactive care program — with regular assessments, recorded service history, and condition reports for every tree on a property — is one of the most effective risk management tools available to commercial property managers, HOA boards, and municipal agencies. When a tree-related incident occurs and questions of due diligence arise, your service records are the answer. A reactive maintenance approach produces no such record.
What Grow It Forward Looks Like in Practice
For a commercial property manager it means receiving a multi-year tree care plan aligned with your budget cycle — not a surprise invoice every time something breaks.
For a city arborist it means a TrimIT®-powered inventory of every street and park tree in your jurisdiction with condition assessments, service history, and projected maintenance costs that give your budget process a factual foundation.
For an HOA board it means documented assessments and a care schedule that demonstrates due diligence to your insurance carrier and protects the association from liability exposure.
For a university facilities director it means a campus-wide tree health program that prioritizes safety in high-foot-traffic areas and forecasts costs across institutional budget cycles.
In every case it means the same thing: making informed decisions today that protect your trees, your property, and your investment for the next decade and beyond.
The Bottom Line
The science of arboriculture is clear: trees respond to the care they receive over their entire lifetime, not just the last service visit. The decisions made at planting, the pruning techniques applied in year three, the root zone assessment that catches a drainage problem before it becomes structural failure — these are the decisions that determine whether a tree thrives for generations or quietly declines for years before anyone notices.
Grow It Forward isn't a tagline. It's what nearly 50 years of doing the work right actually looks like in practice.
