Oak Tree Pruning in Placerville

Is there an oak on your Placerville lot that's due some care? Dial (530) 240-2208. We'll get a Placerville tree trimming company to come walk around it with you. Oak tree pruning in Placerville is slow, careful work. They'll tell you what it needs, and just as useful, what it can skip.

Oaks are the trees people here love and fret over the most. They're old and big, and one bad cut can haunt you for years.

Signs your Placerville oak could use pruning

Good news first. In a UC Master Gardener talk about our local oaks, they come across as tough, hardy and fine with drought. Left alone, most of them do great. Still, a few things deserve a closer look.

• Bare, dead limbs up in the crown that never leaf out in spring.
• One long limb stretched out over the roof, deck or driveway.
• Low branches you duck under every time you mow.
• Clumps of mistletoe spreading through the top.
• A cracked or hanging limb after a windy night.
• Mushrooms at the base, or pink and white froth oozing from the bark.

That last pair is worth explaining. The talk flags foamy bark canker as new to our area. It's a fungus spread by the western oak bark beetle, showing up locally on interior live oaks. Pinkish white foam leaks out of the bark, and the talk calls it likely fatal. Mushrooms near the base can point to root rot instead. Neither is a guessing game, so get a pro's eyes on it.

The summer limb drop problem for Placerville oaks

This one catches newcomers off guard. A big oak can let go of a whole limb on a still, scorching afternoon with no wind at all. The talk calls this summer branch drop.

Limbs that fail tend to be the horizontal ones, somewhere from 3 to 12 feet from the trunk. Here's the unsettling part. Per the talk, they may look perfectly healthy.

What can you do? The talk offers two ideas. Big horizontal limbs above a home, a path or a driveway are better removed. And skip the kind of pruning that makes a limb sprout a heavy mop of new growth.

Hidden rot adds to the risk. UC's wood decay notes say plenty of fallen branches seemed fine until someone checked inside. They also say losing just 10% of a limb's wood weight can cost it 70 to 90% of its strength.

Which oak is it, and when to prune

By the Master Gardener count, our county has 7 oak species that grow as trees and 3 that stay shrubs. Around Placerville you'll mostly meet five of them, listed in the table below.

The pruning rule is short. Winter for oaks that go bare, summer for oaks that stay green. Going bare in winter is all deciduous means.

From the UC Master Gardener talk "Oaks in El Dorado and Amador County," Fall 2020.

Downtown Placerville sits at about 1,867 feet, and the hills around town climb to nearly 4,000. So you're right at the low edge of black oak country. Drive up the hill a ways and you'll spot more of them. Each lobe on a black oak leaf ends in a tiny bristle, the easiest giveaway.

Blue oaks have a trick of their own. The talk says they can go dormant in summer. A wet late spring can also give them powdery mildew and turn them almost white. Nothing needs doing for that, the talk says. They usually leaf out again by the next spring.

What good oak pruning looks like

Good oak work is mostly restraint. The International Society of Arboriculture caps a single pruning at a quarter of the crown, 25%, with mature trees getting even less.

Most oak jobs mix a few kinds of cuts.

• Cleaning out the weak, diseased and dead wood.
• Selective thinning, which opens the crown to sun and breeze.
• Raising, where the bottom limbs come off to clear a roof or walkway.
• Reduction, shortening a long limb back to a smaller fork.

Every cut should sit just beyond the branch collar, that slightly swollen ring at the base of a branch. Heavy limbs come down in stages. The arborist brochure lays out an undercut 12 to 18 inches from the trunk, a second cut from above, and a last cut at the collar. Done that way, the bark doesn't rip.

Topping is a firm no. Per the arborist group, it can take off anywhere from 50 to 100 percent of the leaves a tree feeds on. For an old oak, that's an open door for rot and flimsy regrowth.

Placerville oaks and the county

A light trim is one thing. Taking an oak out is another. According to the Master Gardener talk, El Dorado County adopted its oak ordinance in 2017, and it goes further than state law. Unless an oak is a hazard tree, removing it can mean paying mitigation.

Best practice, the talk says, is getting in touch with the county before you remove any. Inside Placerville city limits, the city is the place to ask. This page is about keeping your oak, though, so most trims won't get anywhere near that.

What oak pruning costs for Placerville homes

Expect oaks to cost more than average to trim. Their wood is dense and their limbs reach a long way. These ranges are national, so use them as a yardstick.

If an arborist does the work, Fixr lists $85 to $120 an hour. A young blue oak out in a field lands near the low end. A huge valley oak over the house on a slope can top the chart.

Ask what the price includes. Hauling the branches? Chipping? Raking up? You'll have the number from the pro before any saw starts.

Looking after an oak between trims

That same Master Gardener talk sums up oak care as "mostly a collection of do nots." These are the big ones.

• Skip summer watering. Extra water in winter during a long dry spell is the one exception.
• Leave the fallen leaves. They're the tree's own mulch.
• No fertilizer and no weed killer around the trunk.
• Don't pile rocks or soil up against the trunk.
• Go easy with the string trimmer. Germs get in through those nicks.
