"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."

"James the owner has it down! Easy communication, straight to the point. Robert who handled the tree stump removal and tree debris pickup was such a hardworking guy. Nonstop work, straight for 7 hours. Very personable as well. Appreciate people like him. Definitely recommend this team to others who need any type of yard work done on their property. I’m glad I choose them😊"

"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

Trimming your palm trees once or twice per year keeps them healthy and robust. Caring for palm trees includes cutting off brown leaves to prevent wildfires and pathway obstruction. However, you don’t want to over-trim the palm tree. Cutting too many branches off will weaken the tree and prevent future growth. And it’s essential to have a strong, healthy palm tree during hurricane season to prevent safety risks or property damage.

You can use herbicides to prevent roots from growing without killing the tree itself, however they must be used with caution. Systemic herbicides are absorbed by the root and can kill off problematic roots. However, herbicides can sometimes negatively impact nearby plants, so the solution is best used sparingly.

You don’t always need a permit to grind a stump, but you might need one depending on your location and the stump’s surroundings. Permits are often needed if the stump is part of a protected tree species, near public areas or utility lines, or close to environmentally sensitive zones like wetlands. Some cities also regulate noise and work hours. Always check local rules before grinding, and contact your city or county office if you're unsure.

The ideal time to prune a tree depends on the type of tree. Typically, late winter or early spring is a good time to prune but isn't always the case for "towering trees." It's best to trim when trees are dormant and before blooms appear but can vary depending on the tree type. It's always best to research the type of tree or ask a professional tree trimmer to determine when is the perfect time to prune your tree.

To maintain trees on a commercial property, perform regular pruning, monitor for diseases, and apply fertilization to promote healthy growth. It is also important to remove any hazardous branches to keep the trees healthy and prevent potential liability issues.
