"P&J does fantastic work. I am more than pleased. Joe is an arborist and has keen knowledge of trees, when and how they should be pruned and groomed or even removed. P&J removed three trees and many shrubs, pruning and shaping many other trees. Stump grinding was done to the removed trees. His crew of seven and himself showed up on time at 8am and they were done at 1130am. Amazing! They are licensed, bonded and insured."

"I was contacted by Eli just after I put a request for prices to do the above work. He made an appointment for the next morning. After I made the decision to hire him, he started the work on the following Monday. He removed two 60 ft. trees. He and his crew were extremely organized and efficient with their time. Trees were removed along with all debris. The cleanup of the both front and backyards were great. I would highly recommend him for work and plan on having him back to prune fruit trees at the proper time."

"The job went like clockwork. Aly was prompt in coming out when contacted to provide an estimate. While the cost for cutting and hauling this very large pine was not inexpensive, it was reasonable given the size of the job and was within the parameters of other quotes I received. I was impressed with the many positive client reviews I read about Aly's Tree Trimming and the fact that the company was bonded, a certified Arborist, and licensed. Aly was able to get his crew over immediately after PG&E had finished their job of cutting near the high voltage lines. Aly has a large crew and they worked quickly and efficiently. Alex the foreman, did a wonderful job working with our difficult neighbor in handling the issues of working on the neighbors property. They cleaned up every day and when a small tree on the neighbor's property was damaged, they replaced the tree with a similar specimen. The crew were very professional and courteous. They avoided any damage to the two properties (other than the tree mentioned above). I would definitely use Aly's Tree Trimming again and would highly recommend it to other clients who are seeking the highest professionalism, and courtesy."

Customers say: Quick response

"They contactly me promptly regarding the project and did an excellent job at a reasonable price. I would recommend them to anyone else for a similar project. My project necessitated the trimming of dead branches from 100' tall redwoods and the removal of smaller redwoods that had been damaged in a fire. They surveyed the site on a Friday and were able to complete the project on the following Monday."

"Oscar and his crew did an amazing job cleaning up my front and back yards, removing two problem trees which were planted too close to the house many years ago, out of control oleander bushes, an overgrown aloe patch and other assorted weeds and plants which had taken over the front and back yards. They worked quickly and efficiently, and left everything as nest as a pin. I could not ask for more and I would definitely hire them again in the future should the need arise. They even fixed a stump which was inadequately removed by a previous tree service company, and informed me of another incomplete stump removal, which I will have the other company come back and address. I would not believe what they were able to accomplish in 5 hours if I did not see it myself!"

Arborists FAQs, answered by experts

Yes, it is essential to confirm that any tree service company you hire is properly insured before they begin work. Tree removal, trimming, and pruning are dangerous jobs, and proper insurance protects you, your home, and the company from liability in case of accidents or damage. Look for a company that carries both general liability and workers’ compensation insurance, and do not hire one that cannot provide proof of coverage. When browsing for professionals, you can look for indicators like an “Angi Approved” badge, which signifies that the business meets standards like holding applicable licenses and passing a background check. Keep in mind that a license is a legal requirement to operate, while certifications are typically voluntary.

It is good to spray water on a Christmas tree to help keep the needles hydrated. Spraying a Christmas tree with water prevents dryness, stops needles from falling off, and reduces the risk of fire.

It is possible to cut down a tree on your property yourself, but it is generally not recommended unless specific conditions are met. You should only consider this project if the tree is small (e.g., under 4-5 inches in diameter and short enough that you don't need a ladder to reach the branches), and you are experienced in handling a chainsaw. The tree must also be located far from any power lines, fences, homes, or other structures. Even for small trees, the work can be dangerous, and it's always advisable to have a spotter to ensure the tree falls correctly and no branches fall on you.

For any tree that is large, requires a ladder to access, or is near electrical lines or structures, you should always hire a professional. Attempting to remove a large tree yourself is extremely dangerous, poses a risk of serious injury, and could result in significant damage to your property.

Before any tree removal, it's also important to check your local and state regulations to ensure the tree is not historic or otherwise protected by your city.

Tree roots are hearty and complex systems, so they don’t die immediately after the rest of the tree is removed. If you leave the root system in place, it takes anywhere from two to seven years for it to run out of nutrients. It is worth noting, however, that the roots stop growing and expanding after cutting down the rest of the tree.

Dutch elm disease can’t harm humans. In fact, according to Cal Fire, bark beetles aren’t even typically dangerous to trees unless that tree is already weakened. The problem comes when Dutch elm disease kills a tree. That tree is more at risk of falling and catching fire, which can pose a serious threat.
