What Is Tree Cabling And Bracing?
Cables are flexible steel, installed high up, and their job is to cap the distance between two stems. Braces are threaded rod, run right through a split, then tightened until the split is clamped.
Neither device heals anything. What they deliver is added safe service life for a tree already on the removal list.
Which Trees Around Burford Need Cabling?
Open-grown trees are the usual tree cabling and bracing candidates. A tree that grew up in a field with no competition spreads wide and often divides into two or three stems close to the ground.
Bark folded down inside that division makes the join unsound from day one, since bark will not bond to bark. Each season of added weight drives the flaw a fraction higher, and sooner or later a wind off the open fields discovers it.
Where Is A Cable Installed?
A cable goes high on the stems, about two thirds of the way out from the crotch toward the tips. Set there, it holds back the worst of the sway without piling load onto one spot.
The give is intentional. Trees lay down strengthening wood only where they flex, so the object is limiting the extremes, not stopping motion altogether.
Should The Crown Be Reduced As Well?
Nearly always. Cut the crown back at the same time and the steel has much less mass working against it, so tree cabling and bracing performs far better.
Left alone, hardware carries mass that a saw would have removed at lower cost. We generally suggest the pair, each itemised separately.
When Is Cabling The Wrong Answer?
Some trees gain nothing from it, and saying so is better than taking the job:
- Rot in the butt, because bracing the top ignores where the tree is actually failing - A fork opened so far that steel by itself no longer makes any difference - Any young tree, since a single well-placed cut fixes it for good at lower cost - A tree in overall decline, where tree removal is the sounder decision
Does Cabling Need To Be Inspected?
Yes, and you will rarely see it written into anybody else's quote. Corrosion works on the steel while the tree quietly swallows its anchors, until there is nothing left to look at from below.
Fifteen unchecked years is long enough for the steel to be doing nothing while the crown overhead keeps expanding on the assumption that it is held. That is why an inspection interval appears in writing on our quote.
