"I would highly recommend Arborist of America for all your tree work needs! William Byrd, owner of Arborist of America, and his crew did an exceptional job in completely removing two 100 foot trees of mine and did it in timely manner with no damages to my or the neighboring properties. William is very professional and very knowledgeable in tree work and trees in itself. I would definitely hire Arborist of America again to carry out any tree work of mine."

"The crew were on time, their work was very organized and thorough. They also trimmed other trees that needed an arborist's expertise. Each crew member did their job efficiently. We had made arrangements for a neighbor to take the wood, so the crew chipped the trimmed branches. They did a good cleanup job. We were very pleased with their work."

"Grass Doctor did a superb job. They showed up on time, removed all the bushes and grapevine trellis very professionally and left the bedding raked and cleaned up. Overall a top notch job. I will be using them again for other projects."

"Pacific Time Trees did a great job removing 2 trees from our yard - one that had died and another that was overgrown in a tight location. Carlos and his crew chipped everything (even chipped an extra pile of trimmings we had!) and left the site clean. Both Cesar and Carlos were very responsive and good about communicating timing for everything. They got the job done quickly, and at a very reasonable price. We will definitely use them for any other tree projects we have!"

"I initially met with Francisco and he was very informative and helpful. He explained the process and I really enjoyed how much I learned from him. I was not home when the crew came to cut my trees but when I returned home I was really happy with what they had done. I would definitely recommend this company."

"We got a call back a couple of days after we called for an appointment, and left our address and the location of the tree so someone could take a look at it . They came over the next day while I wasn't home and called me with the results. They told me that the tree was indeed leaning at ground level, but if you look at it high up it was growing straight as an arrow. It had leaned over in it's youth, but righted itself properly. We had nothing to worry about, he said. He could remove it, and quoted a price, but he didn't think it was necessary. I appreciate his honesty and professionalism and wouldn't hesitate to hire him for tree work in the future."

"I called for an estimate and Douglas came out the same day to discuss the job.  He then scheduled the work for the next day.  He was very easy to talk to, and asked appropriate questions about the scope of work.  The crew showed up the next day, on time, and were all very pleasant and seemed to work exceptionally well together.  Everybody knew what to do and the all went about the work, despite sometimes driving rain that soaked them all.   They remained in good spirits ( i heard them laughing and joking) and worked steadily and productively the whole time they were here.  Everything I'd asked for was done, and the yard looked GREAT!
I would definitely hire them again, and plan on asking them to service my yard next spring for regular maintenance.  A very pleasant and hard-working team.....I felt lucky to have found them!

"Professional, knowledgeable and did a wonderful job. We had 2 large trees removed from our property that were both near our house and they did exactly what we wanted and cleaned up really well. We will absolutely use them again when we are ready to remove other trees from the property."

"I can't say enough good things about my experience with Willamette Valley Tree Service & More. Prior to the job, Rafael made a bid after spending considerable time examining our trees and bushes, which included three mature apple tres that had not had professional care for over six years. Rafael and his crew arrived right on time, and to a person they were professional, courteous and completely focused on the job. Rafael patiently answered all my questions , and explained the benefits our trees and bushes would gain from the trimming. I learned a lot from this experienced, compassionate professional, and will definitely hire Willamette Valley Tree Service & More again!"

Arborists questions, answered by experts

In the case that a tree is growing directly on your property line, the cost of maintaining the tree is shared and is the property of both owners in common. In this case, all decisions regarding the maintenance of the tree must be made jointly, and both parties must agree on a course of action. You will need to agree with your neighbor about the cutting of any roots before you carry it out, and your neighbor must also consult with you before doing any trimming. Coming to an agreement with your neighbor about any shared trees ahead of necessary trimming and maintenance will make this process much simpler.

No, you cannot throw branches from your neighbor’s tree back into their yard, nor can you discard leaves or other plant matter that originated from their yard back over there if it happens to land in your yard. You are responsible for cleaning up plant matter that made its way into your yard.

There are several methods to hollow out a tree stump, and the best one depends on your tools, experience, and priorities. Common methods include using a chisel and hammer, a chainsaw, or burning.

  • Chisel and Hammer: This is often considered the easiest approach for those with limited tools or experience, though it is the most time-consuming.

  • Chainsaw: Using a chainsaw is the fastest method, but it comes with significant safety risks, especially for inexperienced users.

  • Burning: This can be an effective method, but it is not recommended unless you can first drill holes into the stump. Without holes, the stump will be difficult to light and may not burn completely through.

A power drill with at least a ⅜-inch diameter bit can make the job quicker and easier, regardless of the primary method. While you can use a chisel or chainsaw without a drill, it will require more time and effort. Always wear protective goggles and thick gloves, as splinters are an inevitable risk.

Yes, cutting a tree's roots can cause it to fall, particularly if major support roots are severed. In extreme cases, trimming roots can affect the tree's structure and stability. Many crucial roots are located just below the soil's surface. If you make severe cuts to roots more than 2 inches in diameter, you risk impacting the tree's water flow and its ability to withstand severe winds or storms. Even cutting roots less than half an inch in diameter under or outside the tree's canopy can cut off its water supply, causing it to decline, die, and eventually topple.

No. Most of the time, suckers are only a sign that the tree is experiencing stress. However, they can also be the canary in the coal mine, letting you know that something else is stressing your tree. If you have lots of suckers on your tree, calling in an arborist or a tree care expert is always a good call to determine the cause and develop a solution that de-stresses your tree.
