Thinning And Reduction Are Not The Same Job
People often ask for these two in the same breath, but they solve different problems. Thinning means selectively cutting out some of the smaller interior growth, so light and wind can pass through a canopy that still looks like the same tree from the street.
Canopy reduction shortens the longest branches instead, so the whole tree gets smaller while the crown stays just as full. Describe what is actually bothering you about the tree and we can tell you which one applies.
Thinning Helps A Yard That Will Not Grow Grass
Thinning is the answer when a lawn under a big tree stays patchy no matter what goes down, or a garden bed underneath simply will not fill in. Opening the crown lets enough light reach the ground without changing the tree's shape as seen from the street.
Done well, nobody should even notice the tree was worked on. A crown left stripped bare on the inside with growth surviving only in tufts at the branch ends was not thinned correctly, and it leaves those ends heavier and more prone to breaking.
Reduction Helps A Tree Handle Lake Wind
Reduction is the right call when a tree has simply outgrown the space it occupies, or its longest limbs are putting real strain on the trunk every time the lake wind picks up. Shortening those limbs takes the leverage off every fork below them.
Given how shallow roots tend to run in Sarnia's clay ground, cutting that leverage makes a genuine difference in how a tree stands up to a hard west wind coming straight off the water.
We Will Not Top A Tree
Topping cuts the main limbs back to blunt stubs without any regard for where the next healthy branch actually is. It still gets offered around as a fast fix for a tall tree, and the result runs backward from what anyone intended.
The tree answers with a thicket of new shoots barely attached to the surface of each wound. Within a few seasons the regrowth outweighs what was there before while being far less securely attached, and the stubs underneath are already rotting from the inside. This crew turns down topping work, at any price.
