The main benefits of crown thinning
Tree thinning results in higher levels of light passing through the canopy, in turn reducing shading.
Crown thinning also reduces the sail effect of the trees limbs allowing the wind to pass through the canopy, reducing limb frailer if carried out properly.
Thinning reduces overall weight and with the removal of dead, weak, crossing or duplicated branches produces a naturally healthier tree.
