"From the first contact until the work was completed, Pacific Northwest Arborists was a professional, friendly company to do business with. Keith, the owner, came out to bid. I was impressed with how invested he was in saving our trees. Other companies we contacted were encouraging us to remove the trees. Keith offered realistic explanations and solutions to the various problems. Even to the point of saving a sapling shoot that was sprouting from the remaining birch stump in hopes that a new tree would result. The bid was very reasonable. The work performed and the cleanup following exceeded our expectations. I have already recommended Pacific Northwest Arborist to a neighbor and would not hesitate to use their services again."

"My experience with Green Sky Tree Services was excellent from start to finish. When I contacted them to get an initial bid, the receptionist took my info and said she would get back to me soon. I was expecting that to mean a couple days, but she called back within 15 minutes. The arborist, Juan, came out and looked at what I needed done, answered all my questions, and emailed me a bid the very next day. They were booked out about a month at the time, but he was able to fit me in within a couple weeks since it wasn't a large job. He and his crew showed up promptly the day of the job and did a meticulous job trimming one of my maple trees as well as an oak tree. He let me know when he was finished so I could take a look and make sure it was to my satisfaction. The cleanup by Juan and his crew was impeccable. They even went as far as taking care to cut up the large branches with hand saws instead of power saws as to be respectful of my neighbors since they came out early on a Saturday morning. I will definitely be contacting them for any future tree trimming needs."

"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."

"Aaron was very honest that his company could not meet my landscaping maintenance needs as I have a very full landscape.  He suggested a retired fellow who likes to garden who would work with me.  I appreciated his honesty and would recommend him to anyone."

"This company is very professional in their approach and their service is top notch. They pay close attention to detail in how they mow. Juan, the owner, makes sure his staff know exactly what needs to take place in order to produce high quality results. Their signature is in their mowing. You can see the diagonal lines after they do a mowing, and is done with precision. It makes the whole property look beautiful and gives the area a sense of peace. Grass doctor is also prompt. We have used them for over 5 years now and I would recommend their services to anyone, be it professional grounds, or private residence, they have something for all (and their yearly contract includes shrub trimming which saves us a ton of money by not having to hire out for this service. They have even done bark chipping of our playground, digging the old stuff out by hand before laying out the new bark chips. That was true service ! Everyone is warm and friendly and very easy to work with."

"I claimed a deal for four hours of yard clean-up, and I am very happy with the results. A three man crew did the work and left my yard looking in great shape. This is the third year that I've hired this company to do this work and I highly recommend them. I have requested a follow-up visit in February for rose-pruning."

"We hired Robert & his crew for a complete landscape make-over, front and back yards, and are so pleased we did! They exceeded our expectations with their high quality of work. The job foreman, Jorge, and his crew arrived promptly each day. Jorge is an EXCELLENT foreman! We felt like he went the extra mile with all the work he did. He is very conscientious with an excellent work ethic! The crew was very respectful of our property as well as our neighbors. We were very please and impressed on how well the premises was cleaned at the end of each day and especially the last day. Robert stopped by on a daily basis and stayed in contact throughout the length of the project. We were especially impressed when randomly stopped by a month after the completion of the project. He was following-up on the status of the plants after we had a lot of rain, frost and snow. Robert worked closely with us on all aspects of the project. He listened to our desires and suggestions and made sure they were incorporated. He is an enthusiastic professional who loves his work!"

Arborists questions, answered by experts

A dead tree should always be cut down, because it could fall and cause injuries or damage, and it can also attract insects like carpenter ants. A tree that’s diseased beyond repair should also be cut down, but it’s not always easy for a homeowner to tell. Signs of disease include dying branches, a hollow trunk, leaning, and discolored or missing leaves, but your best bet is to hire a local arborist who can evaluate the tree and tell you if it can be saved or should be cut down.

If a tree isn’t pruned, it can inhibit proper growth and fruit production, cause damage to both the tree and your property, and create entry points for pests and diseases. Pruning a tree enhances its stability, appearance, shape, and growth. Pruning trees regularly can also save you money long-term by avoiding overgrown or dangerous dying trees.

Sometimes, knowing when you need tree-trimming services is straightforward, and other times, you have to do some investigating. Some tell-tale signs that you should have your tree trimmed include:

  • A poorly-formed tree with unruly branches, which makes the tree appear odd-shaped. 

  • A tree with tall or large branches that interfere with power lines or your home’s exterior.

  • A tree that provides too much shade in the yard due to branch overgrowth.

Late winter is ideal, but if you’re pruning apple trees in the spring, prune them as early as possible in the season. You want to ensure your tree is just creeping out of dormancy and hasn’t started pushing out new growth. If you prune your tree too late into spring, you generally won’t see results until the following year.

That said, there’s no pruning season for unhealthy growth. Remove dead, dying, or diseased branches as soon as you notice them, regardless of the time of year.

Maple trees start the growing season by developing small groups of red flowers where the tree's fruit, the samaras, will appear in the coming weeks. Later in spring, the samaras, which many call whirlybirds or similar names, develop into single-winged seed carriers that spin when falling or drifting in the wind.
