Thinning And Shaping

Thinning takes select branches out of the inside of a canopy so wind and light move through it. Shaping evens out a canopy that grew heavy on one side. JCC Tree Service does thinning and shaping in Yuba City. Both jobs are about balance and weight, not about making a tree smaller.

A Canopy Stripped on the Inside Gets More Dangerous

Pulling all the small inner branches off a limb and leaving a tuft of leaves at the end is the fastest way to break that limb. The habit has a name in the trade: lion tailing. Inner leaves and small twigs feed the wood closest to the trunk and keep the limb tapered and strong. Strip them and every bit of wind load lands out at the tip, on the end of a long lever. The limb also loses the shade on its own bark, which can scald. Thinning done right removes whole branches spread through the canopy, evenly, and leaves the inner growth alone.

Shaping a Lopsided Tree Is About Weight, Not Looks

A tree that leans toward open light keeps growing that way after one trim, so shaping is a correction you repeat over time. One heavy side loads the root plate unevenly and puts tension on the union at the trunk. Shaping trims the long, heavy side back to living side branches and lets the short side catch up. It is slow. A tree that grew crooked for years does not come square in one visit, and anyone promising that is going to top it instead. Homeowners in Yuba City and the towns around us usually notice the lean after a wind event, when the heavy side is closer to the roof than it used to be.

Thinning Lets Wind Through a Solid Canopy

A dense canopy acts like a sail, and a sail catches everything the wind brings. That matters most on tall, round headed trees with one main trunk and a wide crown. Opening the canopy in a few places lets gusts pass instead of pushing. Light gets to the interior too, which keeps the inner twigs alive instead of shedding them. There is a limit. Take too much and the tree responds with a flush of weak upright shoots, and you are back in a year with a thicker canopy than before.

Trees That Should Not Be Thinned

A stressed tree with thin, small leaves and dieback in the top does not need more wood removed. Leaves are how it feeds itself, and thinning a struggling tree takes food away when it has none to spare. Same with a tree that was topped in the past, because the new growth is all it has. A tree that has been closed in by others for years is another one to go slow on, since bark that never saw direct sun can burn once it is exposed. In those cases the better answer is deadwood removal and time, which falls under regular tree pruning.
