Crown Thinning in Placerville

Has a tree in your Placerville yard turned too dense, too gloomy underneath, or too top heavy? Ring (530) 240-2208. A pro who works this area will stop by, study the canopy with you, and suggest what would help.

"Crown" simply means the leafy upper part. Thinning it takes out some branches, never all, so the tree carries less weight and lets sunshine through.

When a crown gets too much

You usually know it when you see it. Here's what folks tend to notice.

• Nothing grows under the tree anymore because it's so shady.
• Branches cross and rub against each other.
• One side is far heavier than the other.
• Long limbs sag lower every year.
• Wind roars through it and you hold your breath.
• Low branches block the walk, the car or the view.

Lots of these started out as a cute little sapling. Nobody told them to stop. I'd bet that describes half the shade trees in Placerville's older neighborhoods.

Thinning, raising and reduction

These terms get muddled constantly. Here's how the International Society of Arboriculture defines each one.

Cleaning

Wood that's dead, dying, diseased or barely hanging on gets taken out. Nearly any tree is better off for it.

Thinning

Selected branches go, which improves the framework and lets sun and air pass through. Good thinning lightens the load on heavy limbs while the tree keeps its own natural outline.

Raising

Lower limbs come off to give clearance for a house, vehicles, people on foot, or a view. Picture the branch you keep bonking your head on.

Reduction

Here the goal is a smaller tree, often to keep it off a wire. Each cut goes back to a side branch no less than a third the diameter of what's removed. The arborist group says this holds the tree's form and strength far better than topping.

How much should come off

Less than you'd think. The arborist brochure caps any one pass at a quarter of the crown, with older trees losing less.

Here's something many people don't know. Surprising but true: the brochure says thinning on a schedule, just because, doesn't automatically make a tree healthier. Leaves are its kitchen, so stripping lots of them is hard on it.

So every cut in a decent thinning has a purpose. The brochure's wording is blunt: don't remove a branch unless there's a reason.

Removing just one large limb may leave a wound too big to close over, the brochure warns. Pros often prefer several small cuts to one giant one for that reason.

Timing a thinning

For most trees, the arborist group says growth and wound closure peak when you prune ahead of spring's leaf flush. Hold off on heavy cuts in the weeks after that flush, particularly on a weak tree, since it just poured its energy into new leaves.

Then the local twists come in. Pines should wait outside the February to mid-October beetle season, per UC. Deciduous oaks get thinned in winter and evergreen oaks in summer, per the Master Gardener talk on county oaks. Our tree care calendar has the full list.

Topping is not thinning

Every so often someone wants the top "knocked down" to shorten a tree. Please don't. The arborist group labels topping perhaps the single most harmful pruning practice.

A topped tree sprouts a bunch of fast new shoots below each cut. Some species push out as much as 20 feet of new growth in one year, per the brochure. Those shoots hang on weakly and snap in wind or ice. Meanwhile bark that used to sit in shade gets baked, which can mean sunburn, splitting bark and dead branches.

If a tree has to be smaller, reduction is the way. If it's just too big for the spot, sometimes replacing it is kinder. The brochure says the same.

Thinning a crowded group of trees

This is a different job with a similar name. On a lot with lots of pines packed together, UC suggests thinning the stand. That means taking some whole trees out so the ones left stay stronger against bark beetles. If that's what you're after, tell us when you call so the right pro comes out.

What crown thinning costs for Placerville homes

Most guides lump thinning in with pruning. These are national numbers, so they're a rough guide only.

A broad crown on a hillside or above a roof eats up more time. Same with a tree nobody has touched in twenty years. Expect the figure after the pro has seen it, and before a single branch drops.

Why call us

We sketch the tree out for the pro ahead of time, so nobody pulls up expecting a dainty plum and finds a 60 foot pine. Want a second opinion on price? We'll go looking for another pro. Simple as that.
