How Are Thinning And Reduction Different In Practice?
Thinning works from the inside out, removing selected interior branches while keeping the tree's outline essentially the same. Reduction works from the outside in, cutting back the ends of limbs that have outgrown a roofline, a power line, or a neighbouring yard.
Is Cutting Back A Mature Or Older Tree Riskier Than A Young One?
Not inherently - a tree that's stood for decades has already proven its structure is sound, so a well-planned reduction is more likely to extend its useful life than to threaten it, provided the cuts are made in the right places.
Isn't Reduction Basically The Same As Topping?
No, and the distinction matters. Topping chops indiscriminately at whatever height looks convenient, leaving stubs that sprout weak growth; reduction is deliberate about where each cut lands, always ending at a side branch sturdy enough to take over, so the tree keeps its natural form.
