The removal of interior limbs, and in this case ALL interior limbs, has consequences. When side limbs are removed then the mechanism for energy dispersion and growth is removed from a particular area of a tree. These limbs will only have "primary" energy which promotes elongation. The energy for "secondary" growth, or "girth" is bypassed. In other words these limbs will grow longer, but not stronger.
If a picture is worth a thousand words then this video should be a very enlightening demonstration as to how we operate on site.
Here at White Oak Tree Service we are very cautious and are better safe than sorry which is why we put so much effort into proper rigging techniques to keep us and your property safe.
